Heater Control displays the proportional percentage of the heater analog

output.

Electric Heater: The Heater Control % is proportional to the 0-10 VDC signal

being sent to the SCR controller, located in the electric heater control center.

0% Heating = 0 VDC - 0 kW output

100% Heating = 10 VDC - Max kW output

Hot Water: The Heater Control % is proportional to the 0-10 VDC signal being

sent to the heating control valve (BY OTHERS). The heating control output

can be configured to DIRECT / REVERSE acting, along with the minimum and

maximum output voltages by entering the MANUFACTURER menu.

0% Heating = 0 VDC

100% Heating = 10 VDC

Indirect Gas: The Heater Control % is proportional to the 0-10 VDC signal

being sent to the indirect gas furnace controller, located in the indirect gas

control center. The first stage is on at 1% Heater Control. The furnace will then

modulate proportionally from minimum to maximum capacity.

0% = 0 VDC – OFF

1% = 0 VDC – MINIMUM TURNDOWN ENABLED

1 - 100% = 0 - 10 VDC = FURNACE MODULATION

Heat Pump Heating: The Heater Control % displays internal heating ramp as a

percent. Compressor operation is displayed when engaged.

Hot Gas Reheat:

If hot gas reheat is staged control:

“Staged reheat is: ON/OFF” will indicate operation.

If hot gas reheat is modulating bypass damper control:

0% = OFF

1% - 100% = 4 - 10 VDC = AIRFLOW DAMPER MODULATION

If hot gas reheat is modulating valve control:

0% = OFF

1% - 100% = 0 - 10 VDC = HOT GAS REHEAT VALVE MODULATION
