Factory Setting
Control Mode
42.0.0
Sets the external modulation control of a Building Management
System, providing a varying 0-10V input signal to terminals 0-10V IN.
0-10V / Temp – the boiler setpoint temperature is modulated
proportionally to the 0-10V input signal.
0-10V / Power – the boiler power level is modulated proportionally to
the 0-10V input signal.
Disabled
Max
Temperature
42.0.1
Sets the maximum boiler temperature, corresponding to an input
signal equal to the Max Control Signal, when Control Mode is
configured to 0-10V / Temp. (Range = MinTemperature-190°F)
180°F
Min
Temperature
42.0.2
Sets the minimum boiler temperature, corresponding to an input
signal equal to the Min Control Signal, when Control Mode is
configured to 0-10V / Temp. (Range = 68°F-MaxTemperature)
68°F
Control Signal
to Start Heat
Demand
42.1.0
Sets the minimum input control signal required to start a heat
demand. (Range = ControlSignaltoStopHeatDemand-
MinControlSignal)
1.0V
Control Signal
to Stop Heat
Demand
42.1.1
Sets the input control signal threshold where the heat demand is
stopped. (Range = 0-ControlSignaltoStartHeatDemand)
0.5V
Max Control
Signal
42.1.2
Sets the control signal that correlates to the Max Temperature if
Control Mode = 0-10V / Temp or max burner power if Control Mode =
0-10V / Power. (Range = MinControlSignal-10.0V)
9.5V
Min Control
Signal
42.1.3
Sets the control signal that correlates to the Min Temperature if
Control Mode = 0-10V / Temp or min burner power if Control Mode =
0-10V / Power. (Range = ControlSignaltoStartHeatDemand-
MaxControlSignal)
2.0V
