Avoid excessive heating or cooling. Notice that it may take some time for the room temperature to reach the set temperature. Consider using the timer setting options.■Prevent direct sunlight from entering a room during cooling operation by using curtains or blinds.■Ventilate the room regularly. Using the unit for long periods of time requires attentive ventilation of the room.■Keep doors and windows closed when the unit is in operation. If the doors and windows remain open, air will flow out anddecrease the effect of cooling and heating.■Never place objects near the air inlet and the air outlet of the unit. It may reduce the effectiveness or cause the unit to stop.■Turn off the main power supply switch when not using the fan coil unit for long periods of time. Electricity is consumed so long as the switch is on. Turn off the main power supply switch in order to save energy.■Fully use the function of air flow direction adjustment if available. As cold air gathers on the floor and warm air gathers against the ceiling, it is recommended to set the air flow direction during cooling operation parallel to the ceiling and to set it downwards during heating operation. Be sure that you do not direct air flow on to the inhabitants of the room.Sealing member of air discharge outlet KDBHQ55C140Blocking parts to close one or more air outlets of the fan coil unit.Long-lifereplacement filter KAFP551K160High quality filter.Fresh air intake kit KDDQ55C140Kit which can be connected to the ventilation system inorder to supply freshair to the fan coil unit.Remote temperature sensor KRCS01-4Replacement sensor to measure temperature remotely from a location other than that in which the controller is installed.Schedule timer DST301BA51Controller with schedule timing functionality.2-way valve (ON/OFF type)EKMV2C09B7Electronic 2-way valve to control the water supply (+EKRP1C11).3-way valve (ON/OFF type)EKMV3C09B7Electronic 3-way valve to control the water supply (+EKRP1C11).Valve control PCB EKRP1C11Mandatory electronic circuit when 2-way or 3-way valve is used.Optional PCB for Modbus connection EKFCMBCB7Electronic circuit with Modbus interfaceconnections.Wiring adaptor for electrical appendices KRP4A(A)53KRP2A52Electronic circuit with additionalconnections forexternal input/outputsignals.FWCFan coil units4PW65029-1A – 05.2011User manual4 Clean your fan coil unit4Clean your fan coil unitTo clean the outside of your fan coil unit:1Switch off the fan coil unit.2Clean the outside of the fan coil unit with a soft cloth.Never clean your fan coil unit with:■any aggressive chemical solvent,■water hotter than 50°C.For maintenance of your fan coil unit, contact your installer or service company.5Solve problems with your fan coil unitWhen your fan coil unit does not function well, you can try to solve any problem with the corrective actions in this chapter.If the problem persists or is not addressed in this chapter, contact your installer or service company.Your fan coil unit does not functionIf your fan coil unit does not function:Your fan coil unit does not cool or heat wellIf your fan coil unit does not cool or heat well:Your fan coil unit leaks waterShut down the unit and contact your installer or service company.6Dispose of your fan coil unitYour fan coil unit was designed to be environment friendly.

This fan coil model thermostat is capable of supporting fan coil heat/cool, or heat only and cool only systems. A variety of fea-tures are provided including battery operation, separate heating and cooling set points, auto changeover, keypad lockout, and backlighting.OPERATIONThermostat Button Identification — The follow-ing buttons are located on the thermostat display. See Fig. 1 for button locations.•FAN (1) — Selects whether the fan operates at low speed (F1), medium speed (F2), high speed (F3), or auto (only when needed for heating and cooling when in unoccupied mode)•MODE (2) — Selects whether thermostat is set for heat-ing, cooling, emergency heat, auto (heat and cool as needed), or off•UP (3) — Increases the temperature or adjusts the screen selection up when setting advanced features•DOWN (4) — Decreases the temperature or adjusts the screen selection down when setting advanced featuresThe follow-ing on-screen indicators can be displayed on the thermostat dis-play. See Fig. 2 for location of indicators.•Fan mode - on (F1, F2 and F3) or auto (1)•Current temperature (2)•Mode (3)•Fahrenheit or Celsius units (4)•Keypad is locked (no padlock means unlocked) (5)•Battery strength indicator (6)•Auxiliary heat (not used with this thermostat) (7)•Current set point (8)•Second stage is active (cooling or heating if available)(9)Comfort™ ProNon-Programmable Fan CoilCommercial ThermostatSetting Heating and Cooling Temperatures —The thermostat is installed with the heating set at 68 F and the cooling set at 78 F. Perform the following procedure to change the temperature setting:1.To change the heating temperature, press the mode but-ton on the left until the screen displays “heat”.2.Press the up or down button located on the right side ofthe display until the desired temperature is reached.3.To change the cooling temperature, press the mode but-ton on the left until the screen displays “cool”.4.Press the up or down button located on the right side ofthe display until the desired temperature is reached. Turning Heating and Cooling System Of f —To use the thermostat to turn the heating and cooling system off, press the mode button until the display shows “off” in the upper left corner.Advanced Programming — The user can customize two different features on the thermostat, the Fahrenheit or Cel-sius display and the backlighting of the thermostat. FAHRENHEIT OR CELSIUS DISPLAY — The thermostat is preset to display the temperature in degrees Fahrenheit. The user can change the display to Celsius if desired. To change the display, perform the following procedure:1.Press and hold the mode button for about three seconds.The screen will display a flashing “U1”. Press the mode button and the letter F will flash.2.Press the up or down button on the right to change itfrom F (Fahrenheit) or C (Celsius).3.Press the fan button on the left to exit this screen. BACKLIGHTING — The thermostat can be set to have the backlighting either off or on. To change the backlighting selec-tion, perform the following procedure:1.Press and hold the mode button for about three seconds.The screen will display “U1”and the letter F or C in the center.2.Press the up button once. The display will show a flash-ing “U2”.3.Press the mode button again and the On or Off will flash.4.Press the up or down button located on the right side ofthe display to change it from Off to On or On to Off.5.Press the fan button on the left to exit this screen. Using the Fan — For three-speed fan coils, there are three continuous fan speeds. Pressing the fan button cycles through the following selections, fan low speed (F1), fan medi-um speed (F2) and fan high speed (F3) or fan auto. The fan will operate continuously when in F1, F2 or F3. When the fan is in auto, the fan only runs when the equipment is running. NOTE: If the thermostat is set up as a two-pipe auto fan coil system (2A) with electric heat, it has only two relays to drive the fan speeds so the available fan speeds are either low or high. The display will show “F1” for low fan speed and “F3”for high fan speed. For fan coil applications of either two-pipe cool only or two-pipe auto fan coil systems (2C and 2A), the fan speed is high when the electric heat is energized regardless of the user setting.Auto Changeover — The thermostat displays one of five modes: heat, cool, Em heat, heat cool (auto mode) and off. When the mode selection is in auto mode, the system is allowed to switch from heating to cooling or from cooling to heating to maintain the temperature set points.Unlocking the Keypad — The thermostat is locked when the padlock symbol is shown on the thermostat display.A locked thermostat will inhibit a user from making adjust-ments.The method by which the thermostat is unlocked is config-ured by the installer. Three unlocking options are available:1.The user must simultaneously depress the up and downbuttons for 5 seconds.2.If a set of dashes are displayed, then a four-digit pass codemust be entered by the user.3.The user must simultaneously depress the up and downbuttons for 5 seconds, and then enter a four-digit passcode.Using Emergency Heat — Emergency heat is used when the heat system cannot keep up with demand. If Emer-gency Heat has been configured by the installer, it is used if the primary heat source fails. There is no Emergency Heat option if the thermostat is configured as a four-pipe system. To set the thermostat to use emergency heat, press the mode button until display shows Em Heat in the upper left corner of the display.Power Outage — If the building loses electricity, the thermostat will not need to be reprogrammed. The settings are retained in memory.TROUBLESHOOTINGThere are system error messages that may appear on the thermostat screen. See text below for possible system error messages and their meaning.Space Temperature Sensor Failure — If the space sensor reads less than –50 F or greater than 150 F for 60 consecutive seconds, the sensor is considered failed.If the space temperature sensor fails, the Y1 for all fan coil units and W for fan coil units with Emergency Heat mode set to On, will turn off. The space temperature display shows "- -"and the fan will continue to run.If the space temperature is the average of both the local and remote sensors and one of the sensors fails, the thermostat con-trols the valid sensor only. The display alternates every 10 sec-onds between "- -" for the invalid sensor and the reading from the valid sensor.Fan Error — If the thermostat is in the unoccupied mode, fan auto cannot be changed to continuous fan mode (or F1, F2, F3). An E7 error message will be displayed in the space tem-perature digits for three seconds, but the fan selection will not be changed.Battery Icon — The battery icon appears on the display only when the batteries start to lose power. Replace the batter-ies when one bar is displayed inside the battery shell. If the thermostat is battery powered and the icon is just a silhouette with no black bars, the thermostat will slowly lose functions until it does not work at all.Changing Batteries — The thermostat can be powered by the HV AC equipment or by battery power. If there is no lighting until the user touches a button, it is battery powered.When the thermostat uses electricity, the batteries (if installed) take over if the electricity goes out.When powered by batteries, the thermostat's two AA batter-ies should last about one year. When the batteries have lost about one-third of their power, a battery icon shows up on the display in the upper right corner with two black bars. If two-thirds of battery power is lost, the battery icon will display one black bar. As the batteries get weaker, the icon goes down to one bar and then none. When the battery icon is less than full, backlight function will be lost. When the batteries are com-pletely dead, the thermostat will be unusable.It is recommended that the batteries be replaced at the one bar level with two AA alkaline batteries. Batteries are located in the back of the thermostat, so the thermostat will have to be removed from the wall.2To replace the batteries, perform the following procedure: 1.Locate the latch at the top of the thermostat. The latch islocated at the center of the top rim.2.Press the latch down. This will disconnect the thermostatfrom the top of the wall plate.NOTE: The HV AC equipment will shut down.3.Remove the thermostat from the wall bracket completelyby moving it slightly toward you and lifting it up and off the lip on the lower edge of the wall bracket.4.Set the thermostat face down on a flat surface. The batter-ies are located in the lower right corner.5.Remove and recycle the old batteries.6.Install new batteries.7.Replace the thermostat on the wall bracket by lining upthe two slots on the bottom edge of the back of the ther-mostat with the two lips on the wall bracket.8.The HV AC equipment will start back up based on theprevious configuration settings.3Copyright 2011 Carrier CorporationManufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

Refer to the Terminal Designations section for complete information on LTEC wiring designations for 550-534 through 550-537 controllers.Document No. 550-598 Installation InstructionsRev. 1, May, 2002Siemens Building Technologies, Inc. Page 3 of 107.For input type selection, (digital, voltage, or current) see the jumper and connection information in Table 2.NOTE: Each DO provides a normally open (NO) and24 Vac hot (H) terminal. Terminate both connections of a 24 Vac load directly to the controller board. Floating control actuators require 2 DOs and use 3 wire connections.The 24 Vac Common is switched through theTriac when the associated DO is energized. CAUTION:The controllers Digital Outputs (DOs) control 24 Vac only. The maximum rating is 12 VA for each DO. Use an interposing 24Vac relay for any of the following:• VA requirements higher than the maximum• 110 or 220 Vac or higher • Control load requires DC power • Separate transformers used to power the load•Need for dry contacts8. Plug the room temperature sensor (RTS) cable intothe ‘RTS’ port on the left side of the controller. See Figure 3. 9. Remove one of the controller neuron ID labels (twopart label located at the top of the controller board). Record this number as directed in a floor planlayout, job log or place the self-adhesive label on the outside of the controller case or inside the RTS cover. NOTE: This number is unique to the controllerelectronics.Power WiringEach Controller requires a source of 24 Vac, 60 Hz Class II power supply. The base rating of the controller and the sum of the sensor, actuators and relay connected dictates the VA rating.Bus Trunk WiringBus wiring must be accomplished using approved cables only. These include unshielded and shielded (wherespecified) two conductor 22 AWG Level IV cable.WARNING:Use the recommended LonWorks cable: 22 AWG shielded or unshielded, Level IV per NEMA standards (not equivalent to EIA/TIA Level 4 cable). Connect Air brand cable, 22/1 pair, stranded, unshielded, blue plenumjacketed, Level IV, Part Number W221P-2001 or an approved equal for bus wiring. Bus wiring is NOT polarity sensitive.The LTEC Controllers use the FTT-10 transceiver that allows free topology wiring. This includes T-taps, stars, branches, loops as well as standard daisy chain. In all cases, max bus wire length, including each sensor cable, cannot exceed 500 meters (1640 feet). For bus lengths that exceed 500 meters, (1640 feet) a two-port or three-port repeater can be used (Part number 587-450 and 587-455 respectively). This will allow three separate bus lengths of 500 meters. See the LonTalk Two and Three Port Repeater installation instructions, (P/N: 550-310) for additional information and limitations.Each bus segment (1 without repeater, 3 with repeater) requires a pair of terminating resistors (Part number 587-649 – packs of 100) that can be located togetheranywhere on the segment, at the field panel or repeater. The installation is now complete.Document No. 550-598 Installation Instructions Rev. 1, May, 2002Page 4 of 10 Siemens Building Technologies, Inc.Terminal DesignationsFigure 4 shows the LTEC wiring designations and internal jumper locations for both controllers.NOTE: All inputs and outputs physical connections arepre-configured per application number selected.The wiring diagrams (Figure 5 through Figure 9) are shown using the full pointcontrollers (shaded terminals).

The location of physical inputs must match a specific application wiring diagram; see Figure 5 through Figure 9.Output PortsLTECs have configurable, flexible output ports. Wiring diagrams (Figure 5 through Figure 9) indicate how these outputs are used in each application.NOTE: Each application has pre-assigned outputconfigurations. Some models have only the first six Digital outputs and no Analog outputs, while other have all eight Digital outputs and two Analog outputs.Replacing a ControllerNOTE: Replacement of a LTEC requires you to record,re-enter, and/or update the initial point values from the old controller before replacing it. LTEC Network Connections (data sharing between controllers; Connections tab in Network Management Tool) (NMT) do not need to be recorded if using NMT’s Replace feature. NMT will re-apply the Connections after the Replace . However, if the old controller is to be deleted in NMT, then all connections will need to be recorded first so they can be re-entered after the new controller is added.Document No. 550-598 Installation Instructions Rev. 1, May, 2002 Page 6 of 10 Siemens Building Technologies, Inc.1. To record Initial Values, before disconnecting the old controller, do one of the following:•If the controller is communicating with the field panel, update the controller initial values at the field panel.•If the controller does not communicate with the field panel, but does communicate with theNMT, record the appropriate configuration points on Table 3 at the end of these instructions. •If the old controller is not communicating at all, record all data available in the Point Definition Report, or from the last valid initial values uploaded from the controller.2. Disconnect power to the controller (remove the power connector, terminal block J1).3. Disconnect all input and output removable terminal blocks and insure they do not short out.4. Remove the RTS and network (RJ11) connectors.5.Remove the controller board by pressing the internal tabs and lifting the board out (or the complete controller, by removing the mounting screws).6.Install the new controller board (or base and board). 7. Install jumpers.•Ensure jumpers for AI/DI 3 and AI/DI 4 areconfigured to match the removed controller. (See Table 2)•Ensure AI/DI 1, AI/DI 2 and AI/DI 5, external jumpers, remain in place or are reinstalled. 8.Remove one of the Neuron ID labels (two part label located at the top of the controller board). Record this number as directed; on a floor plan layout, job log or inside the RTS cover.NOTE: This number is unique to the controllerelectronics. It is imperative that the old neuron label be removed or covered.9. Reconnect input and output terminal blocks. 10. Reconnect RTS and network (RJ-11) connectors. 11. Reconnect power to controller, terminal block J1. 12. Connect NMT to the LTEC or L model MEC. 13. Run NMT and use Replace to replace the oldcontroller with new one. NOTE: If the replacement controller was previouslyused elsewhere (not in factory packaging) the factory defaults must be re-established as follows:Using NMT, select the controller, selectApplication Configuration and apply the Set to Defaults command. 14. Apply the appropriate Configuration Template. 15. Restore initial values as follows:•MMI: If a field panel update was performed, the LTECs initial values will be loaded automatically.•NMT: If a field panel update was NOTperformed, set the initial values previously recorded in Table 3.16. NMT: Verify LTEC Connections are correct, updateas needed.17. Save the peak database (.pkd file) to flash/file asneeded. Replacement installation is complete.Disposal As an aid to environmentally responsibledisposal, the larger plastic components bear a recycle symbol. The controller should not be disposed of with domestic waste. The printed circuit board and plastic components should be disposed of separately in accordance with local regulations.Document No. 550-598 Installation InstructionsRev. 1, May, 2002Siemens Building Technologies, Inc.Page 7 of 10LTEC FC Application Wiring DiagramsNot available on reduced point controller boards.L O N 8050W D R 1Aux Htg.CoilOnly available on Unit Vent Controller.Figure 5.
