H/L PC -A<br />
Represents the status of Universal Input 9. The high<br />
pressure cutout and low pressure cutout for circuit A,<br />
are wired in series. When tripped, the high pressure<br />
cutout requires manual reset, press the red button on<br />
the switch to reset. The low pressure cutout is<br />
automatically reset when the pressure is above the<br />
mechanical limit of the switch. The pressure cutout<br />
switches are located in the <strong>com</strong>pressor section of the<br />
unit.<br />

Reheat Pct<br />
The capacity (in percentage) being delivered by the<br />
hot gas reheat valves and coil if installed. Hot gas<br />
reheat is controlled by dehumidification logic and in<br />
cooling mode to maintain the supply air temperature<br />
at setpoint.<br />

CWVLV Action<br />
Used to change the operation of the modulating<br />
cooling output that controls the chilled water valve (if<br />
applicable). In Direct Action the output delivers<br />
0VDC at 0% and 10VDC at 100% cooling capacity.<br />
In Reverse Action the output delivers 10VDC at 0%<br />
and 0VDC at 100% cooling capacity.<br />
