This screen only appears if a heating operation was provided with the unit.

When the Heating Control is in the MANUAL mode, use the arrow buttons to vary

the heating 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).

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. The furnace is subject to

minimum On/Off times and Heating Lockouts.

0% = 0 VDC – OFF

1% = 0 VDC – MINIMUM TURNDOWN ENABLED

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