Reverse acting output (Q1 only) is set to direct action (cooling).Analog changeoverWhen the X2 input exceeds the setpoint, summer operation is selected. Reverse acting output (Q1only) is set to direct action (cooling).A contact between terminals D1 and M can be used to implement setpoint changeover for day/night operation.When the contact is open, the setpoints for day operation are selected.When the contact is closed, the setpoints for night operation are selected.During the night mode, the following auxiliary func-tions are disabled: remote setpoint, abso-lute/Relative limiter, setpoint compensation andmaximum priority.Cascade control Maximum PrioritySetpoint compensationWinter/Summer operationDay/night setpoint6/11Mechanical design The RWD32 & the RWD82 universal controllers are as per DIN 43 880 Gr. 1 require-ments.A protective housing is used to protect the controller when mounted outside a control panel, such as on ducts, walls and in plant rooms.

It provides you with a printout of the controller settings. This tool allows controller programming prior to installation.FunctionsController TypeThe RWD62U is a stand-alone universal controller, which performs both primary and auxiliary control functions. The respective mode is defined by entering thecorresponding configuration and setting parameters via the push buttons on the controller or the software tool.Main FunctionsThe RWD62U controller can be programmed as follows: • One sequence: Y1 or Y2 Reverse or direct acting • Two sequences: Y1 and Y2 Reverse and direct acting or Y1 and Y2 Reverse and reverse acting orY1 and Y2Direct and direct actingNOTE: Direct Acting – As air temperature increases, the control output increases.Reverse Acting – As air temperature increases, the control output decreases.T H 0599R 3= TEMPERATURE SENSOR = AIR DAMPER ACTUATOR = HEATING COIL = COOLING COIL= HEATING OR COOLING COIL (TWO-PIPE)= FAN OR PUMP = TIME CLOCK= REMOTE SET POINT UNIT = OUTSIDE AIR SENSOR++--Figure 1.

Two Direct Acting Cool or Two Reverse Acting Cool Sequences(Application 50 to 59).Universal Input X1 The primary input for a Siemens Ni 1000 temperature sensor, a Pt 1000 temperaturesensor, or a 0 to 10 Vdc active input.Universal Input X2The secondary input for a Siemens Ni 1000 temperature sensor, a Pt 1000temperature sensor, an active/passive remote setpoint transmitter, or a 0 to 10 Vdc active input.Digital Input D1 Selects the day/night changeover. Changeover occurs via potential-free dry contacts between D1 and M. Typically, a time clock controls D1 input.Analog Outputs Each output (Y1, Y2) can be configured for either reverse or direct acting. Themodulating voltage output (Y…) controls the devices requiring a 0 to 10 Vdc signal.ExampleT H 0791R 1Figure 7.

Page 5Technical InstructionsRWD62U Universal ControllerDocument Number 155-737 January 14, 2005P+I Limiter Function NOTE: In the followingillustrations, the heating and cooling outputs are D.A. Outputs can be reversed.T H 0794R 1Figure 9. P+I Limiter Function.The limiter function with P+I control enables absolute (or relative) maximum or minimum limitation of the supply air temperature (X2).When the value drops below or exceeds the limiter setpoint, the limiter function controls and takes priority over the main setpoint.Remote SetpointNOTE: You cannot selectthe remote setpoint auxiliary function in Night mode.T H 0793R 1Figure 10. Remote Setpoint.A remote setpoint transmitter (QAA25U), connected to X2 and configured accordingly, enables setpoint adjustment.Active measurement from 0 to 10 Vdc corresponding adjustable range from –100 to 8000 unitsPassive measurement from 0 to 1000 Ω corresponding adjustable range from –100 to 8000 units Cascade ControlT H 0794R 1Figure 11. X2 Supply Air TemperatureSensor.You can select the P+I/P+I room/supply air temperature cascade control. In this case, the virtual P+I room temperature controller determines the setpoint within the limiter setpoints for the P+I supply air temperature controller.Maximum PriorityNOTE: You cannot selectthe maximum priority auxiliary function in Night mode.T H 0795R 1Figure 12. Maximum Priority,Cooling.If the value (0 to 10V) of the input X2 is greater than the calculated output of the cooling sequence, the output will use the X2 input value as output value. This is active even when the controller is working with the heating sequence. Setpoint CompensationT H 0796R 1Figure 13. Setpoint Compensation.The temperature setpoint X1 is shifted by the temperature as measured at sensor X2.Configuration of the RWD62U defines the influence on setpoint X1. The example shows the room airtemperature setpoint as shifted by the outside temperature.Page 6Siemens Building Technologies, Inc.RWD62U Universal Controller Technical Instructions Document Number 155-737January 14, 2005Winter/Summer OperationT H 079Summer Setpoint Winter SetpointFigure 14. Winter/Summer Operation.A digital switch or analog input between terminals X2 and M will implement winter/summer changeover.When adjusting setpoints, the heating setpoint must be less than the cooling setpoint.Digital changeoverWhen the contact is closed, summer operation is selected. Reverse actingoutput (Y1 only) is set to direct action (cooling).Analog changeoverSummer operation is selected when the X2 input exceeds the setpoint Reverse acting output (Y1 only) is set to direct action (cooling).Day/Night SetpointT H 0798R 1Figure 15. Day/Night Setpoint.A contact between terminals D1 and M can be used to implement setpoint changeover for day/night operation.When the contact is open, the setpoints for day operation are selected.When the contact is closed, the setpoints for night operation are selected. During the night mode, the following auxiliary functions are disabled: remote setpoint, absolute/relative limiter, setpoint compensation and maximum priority.Mechanical DesignProtective Housing ARG62.21 • This UL-approved plastic housing protects the controller when mounted outside a control panel, such as on ducts, walls and in mechanical rooms. This housing also prevents inadvertent contact with voltage supplying parts such as the connecting terminals. • The RWD62U clips into the housing.• The cable entries are located at the top and the bottom of the ARG62.21 housing. • The front has an opening for the LCD display and the programming buttons.TerminalsPlug-in screw terminalsSiemens Building Technologies, Inc.Page 7Technical Instructions RWD62U Universal Controller Document Number 155-737January 14, 2005Operating and Display Elements The RWD62U is operated by the buttons on the controller front.Additional tools are not necessary. The controller can also be programmed via the software tool, which plugs into the nine-pin port.Function ButtonsFigure 16.

A On a DIN rail at least 4.7 inches (120 mm) long B Wall-mounted with two #6 screws CFront-mounted using standard hardware: • One DIN rail 5.9 inches (150 mm) long • Two hexagonal blocks 1.97 inches (50 mm) • Washers and screws DIn the ARG62.21 protective housingT H 0741R 1A B C DFigure 17. Mounting Options.Electrical Installation NotesCAUTION:• Standard cables can be used for the controller. However, when mounting in an environment greatly exposed to Electrical Magnetic Interface (EMI), use only shielded cables. • The RWD62U is designed for 24 Vac operating voltage. • Use safety insulating transformers with double insulation; they must be designed for 100% duty. • When using several transformers in one system, the connection terminals G0 (ground) must be galvanically connected. • Supplying voltages above 24 Vac to low voltage connections may damage or destroy the controller or any other connected devices. • Connections to voltages exceeding 24 Vac endanger personal safety. • The ARG62.21 Protective Housing does not provide grounding between conduit connections. Use grounding bushings and jumper wires or equivalent.Commissioning NotesA commissioning booklet is included with the RWD62U controller. Observe the following:• The controller must be configured for application-specific operation using the standard application number. • Application-specific fine tuning can be performed if required (see the commissioning booklet ).• Power supply to the controller and the connected devices must be guaranteed. • Values and settings entered remain available even on power failure.Siemens Building Technologies, Inc.Page 9Technical InstructionsRWD62U Universal ControllerDocument Number 155-737 January 14, 2005Wiring DiagramsT H 0800R 1D1 Digital input G, G0 24 Vac supply M Ground (G0) for signal inputs and universal inputs and analog outputs X1 Signal input (main input: Siemens Ni 1000, Pt 1000 and 0 to10 Vdc) X2 Signal input (aux.
