COOLING STATUS IS DISPLAYED, ALONG WITH COMPRESSOR OPERATION. (IF EQUIPPED)

This screen appears if a cooling option is provided.

Chilled Water: The Cooling Control % is directly proportional to the 0-10 VDC

output signal.

0% Cooling = 0 VDC

100% Cooling = 10 VDC

The cooling control output can be configured to DIRECT / REVERSE acting,

along with the minimum and maximum output voltages by entering the

MANUFACTURER menu.

Packaged DX Cooling: The Cooling Control displays internal cooling ramp as a

percent. Compressor operation is displayed when engaged.

• D = Digital Scroll Compressor Operation

• 1 = First Staged Compressor Operation

• 2 = Second Staged Compressor Operation

Heat Pump Cooling: The Cooling Control displays internal cooling ramp as a

percent. Compressor operation is displayed when engaged.

• 1 = First Staged Compressor Operation

• 2 = Second Staged Compressor Operation

HEAT AND REHEAT OPERATION IS DISPLAYED. (IF EQUIPPED)

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.

• 1 = First Staged Compressor Operation

• 2 = Second Staged Compressor Operation

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
