Unit Controls
These messages only appear and are programmable
when EEV is selected as the expansion valve type in the
Service Mode. EEV must only be selected when an EEV
is installed. Superheat is programmable between 10°F
- 15°F. A setpoint of 12°F - 15°F is recommended.
* The minimum discharge pressure allowed is 160 PSIG. The fan differential Off Pressure will be lowered to prevent going below 160
PSIG based on where the fan control On Pressure is programmed.
