This item also displays the time and date.Spare InputSet the function of the Spare Input Terminal (SL):IgnoreInput (SI) should be wired to a flow switch inserted in the flow of the of the primary system pump. Input(SI) indicates the primary system pump is operating. If output (SO) is set to System Backup Pump,system pump output (SO) is energized and System Pump Feedback is de-energized the SystemBackup Pump output (SO) is energized.When the Fuel Valve Energized input (SC) is not energized and input (SI) is energized the modulationrate is set to the “Low Fire Spd” setpoint. When input (SI) is not energized the modulation rate is set to“Fan Purge Spd” setpoint. When the fuel valve energized input (CS) is energized input (SI) is ignored.Specifies whether high and low cas pressure switches are connected to input (GP).Enables Fuel Limit Hold and alarm messages. (No)Spare OutputSets the function of the Spare Output Terminal (SO):Never close output (SO).Closes SO relay with a call for heat, Opens SO relay 2 minutes after call for heat has been deactivated.Closes when System Pump output is activated but the System Pump Feedback indicates the PrimarySystem Pump is not operating.Close when any alarm is active.54
