EXERCISINGIf the boiler pump has not operated at least once every 70 hours, the control turns on the output for 10 seconds.This minimizes the possibility of the pump seizing during a long period of inactivity.When either m ode 1 or 2 is selected, the water tem perature is controlled based on a fixed setpoint.The setpoint temperature is set using the BOIL T ARGET item in the Adjust menu.HEAT DEMAND(Dem 1)A heat demand is required whenever heat is required for the setpoint load.A heat demand is generated when a voltage between 24 and 120 V (ac) is applied across the CD (common demand) and the Ht D (heat demand).Once voltage is applied, the control turns on the Dem 1 segment in the display.The control closes the pump contacts, which starts the boil-er pump and the control turns on the boiler pump segment in the display.If the operating sensor is 1/2 of the differential below the BOIL T ARGET, the control then closes the Stage 1 contact.The boiler target temperature is set using the BOIL T ARGET item in the Adjust menu.If the operating sensor reaches 1/2 of the differential above the BOIL T ARGET setting, the boiler burner is shut off.The pump contact remains closed until the heat demand is removed and Pump DL Y setting expires.8Model SF-10 Control Instructions ManualModel SF-10 Control Instructions Manual910Model SF-10 Control Instructions ManualWhen mode 7 is selected, the control allows for an external control to operate the boiler through an analog direct drive input signal provided by a boiler sequencing control such as a tekmar Boiler Control 265.When in mode 7, the external heat demand (CD and Ht D) and the DHW demand (CD and DHW D are disabled.DIRECT DRIVE INPUT SIGNALAn external boiler sequencer provides a positive 0-10 V (dc) input signal to the control +V(in) input (pin 10).The negative V (dc) signal is applied to the Com/- input.The boiler burner remains off while the direct drive input signal range is between 0 to 0.5 V (dc).The Stage 1 contact remains on as long as the direct drive input signal is over 0.5 V (dc).PUMP OPERATIONThe pump contact close as soon as the direct drive input signal reaches 0.5 V (dc).Once the direct drive inputsignal falls below 0.5 V (dc), the pump continues to operate until the Pump DL Y purge expires, then the pump shuts off.BOILER MAXIMUM TEMPERATUREThe external boiler sequencer is able to operate the boiler tem perature.However, the BOIL MAX setting lim its the highest temperature at the boiler outlet sensor.Should the boiler outlet temperature exceed the BOIL MAX setting, the Stage contact is opened to shut off the burner.The burner remains off for the minimum off time and the boiler outlet temperature falls 2°F (1°C)below the BOIL MAX setting.When modes 1, 2, 3, 4, 5, or 6 are selected, the control is able to override the heat demand operation and respond to heat an indirect domestic hot water (DHW) tank.DHW DEMAND (Dem 2)A DHW demand is required whenever the indirect DHW tank requires heating.A DHW demand is generated when a voltage between 24 and 120 V (ac) is applied across the CD (com m on dem and) and the DHW D (DHW dem and).Once voltage is applied, the control turns on the Dem 2 segment in the display.The control closes the DHW pump contacts, which starts the DHW pump and the control turns on the DHW pump segment in the display.BOILER TARGET DURING DHW OPERATIONThe boiler target temperature is at least as hot as the DHW BOIL T ARGET setting.If a heat demand is present during a DHW demand, the boiler target is the higher of the two temperatures.DHW OPERATION WITH PRIMARY / SECONDARY PIPINGWhen the boiler is piped in primary /secondary to the boiler and MODE is set to 2, 4, or 6, the control operates the boiler pump together with the DHW pump.ΩIt is often desirable to have priority for the DHW tank.is achieved by lim5.•When DHW MODE is set to 1 there is no DHW priority.•When DHW MODE is set to 2 there is DHW priority.DHW FULL & CONDITIONAL PRIORITYThe control provides full DHW priority when BOIL MIN is set to OFF.This is intended for use with condensing boilers. The control provides conditional DHW priority when BOIL MIN is not set to OFF.Should the DHW and the heat demand Array space heating occurs.to the OUT STthe OUT STDHW POST PURGEAfter the DHW Demand is removed, the control performs a purge on the boiler.In MODE 1, 3, or 5 (parallel piping), the control shuts off the burner and continues to operate the DHW pump.In MODE 2, 4, or 6 (primary / secondary piping), the control shuts off the burner and continues to operate the DHW pump while the boiler pump is turned on.This purges the residual heat from the boiler into the DHW tank.The control continues this purge for a maximum of two minutes or until the boiler supply water temperature drops 20°F (11°C) below the boiler target temperature during the DHW operation.The con-trol also stops the purge if the operating sensor temperature is close to the current boiler target temperature.DHW MIXING PURGEAfter DHW priority, the space heating zones m ay have cooled off considerably after being off for a period of tim e; meanwhile, the boiler is hot.To avoid thermally shocking the boiler after DHW priority, the control shuts off the burner, but continues to operate the DHW pump while restarting the boiler pump.This allows some of the DHW tank return water to mix with the cool return water from the zones and temper the boiler return water.12Model SF-10 Control Instructions ManualPowered Input Connections24 V(ac) PowerConnect the 24 V(ac) power supply to the C and R pins.This connec-tion provides power to the microprocessor and display of the control.Aswell, this connection provides power to the Alarm pin from the R pin.Heat DemandT o generate a heat demand, a voltage between 24 V (ac) and 120 V(ac) must be applied across the CD (common demand) and the Ht D(heat demand) pins.DHW DemandT o generate a DHW demand, a voltage between 24 V (ac) and 120 V(ac) must be applied across the CD (common demand) and the DHWD(DHW demand) pins.Caution:The same power supply must be used for both the heatdemand and DHW demand circuits since they share the CD (com-mon demand) pin.Output ConnectionsBoiler Pump ContactThe Pump pins are an isolated output in the control.There is no poweravailable on these pins from the control.This output is to be used as aswitch to either make or break power to the boiler pump.Since this isan isolated contact, it may switch a voltage between 24 V (ac) and 120V(ac).Model SF-10 Control Instructions Manual13Note:Note:An14Model SF-10 Control Instructions ManualExternal InputThe control can accept an external input signal from an external control.If an external input signal is required, connect the positive 0-10 V (dc) wire to the +V(in) pin and connect the negative 0-10 V (dc) wire to the Com/-.R 2216Model SF-10 Control Instructions ManualApply power to the control. the brochure.Model SF-10 Control Instructions Manual17MODE1 and 2 – Setpoint & DHW Operation MODE1 SETPOINT & DHW OPERATION – PARALLEL PIPINGModel SF-10 Control Instructions Manual 19MODE1 and 2 – Setpoint & DHW Operation20Model SF-10 Control Instructions ManualMODE3 and 4 – Outdoor Reset & DHW Operation MODE 3 – OUTDOOR RESET AND DHW OPERATION WITH PARALLEL PIPINGThe control receives a heat demand provided from zone valve end switches or a switching relay end switch.The control22Model SF-10 Control Instructions ManualModel SF-10 Control Instructions Manual2324Model SF-10 Control Instructions ManualMODE5 and 6 – External Target TemperatureMODE 5 – EXTERNAL TARGET TEMPERATURE INPUT & DHW OPERATION-PARALLEL PIPING The control receives a heat demand provided via an external analog input signal from an EMS, BMS or tekmar tN4 system control.The external analog input signal is interpreted as a setpoint target temperature.The control turns on the boiler pump and operates the boiler to maintain the setpoint boiler target temperature at the boiler outlet sensor.The control receives a26Model SF-10 Control Instructions ManualModel SF-10 Control Instructions Manual2728Model SF-10 Control Instructions ManualMODE7 – External Direct Drive Operation MODE 7 – EXTERNAL DRIVE OPERATIONRELOAD FACTORY DEFAULTSTo reload FACTORY DEFAULT SETTINGS, press and hold the outside buttons (Item and Down) while powering the control up.This will reload the FACTORY DEFAULTS.30Model SF-10 Control Instructions ManualModel SF-10 Control Instructions Manual31SLANT/FIN CORPORATION,Greenvale,N.Y.11548 • Phone:(516) 484-2600 FAX:(516) 484-5921•Canada:Slant/Fin LTD/LTEE,Mississauga, Ontario。

温控器接线图POWER UP PROCEDURE启动程序Verify all electrical connections have been properly made before applying power to the instrument.If the instrument is being powered for the first time, it may be desirable to disconnect the controller output connections. The instrument will be into control following the power up sequence and the output(s) may turn ON. During power up, a self-test procedure is initiated during which all LED segments in the two front panel displays appear and all LED indicators are ON. When the self-test procedure is complete, the instrument reverts to normal operation如果仪器首次被驱动的,它可能要断开控制器输出连接。
