Unit Controller Operation
Dynamic Set Point Ranges and Defaults
Some settings have different ranges of adjustment based
on other parameters and unit configuration. The condenser
settings that follow are applicable to four configuration groups:
1 - Models 30 to 70
2 - Models 75 to 241 with no fan VFDs or one VFD per circuit
3 - Models from 75 to 161 with 2 fan VFDs per circuit
4 - Models 170 to 241 with 2 fan VFDs per circuit
Special Set Point Operation
EXV settings are only visible if the unit is configured with
electronic expansion valves. The EXV position set point is not
changeable unless the unit switch is off.
EXV Position set point on each circuit follows the actual EXV
position while EXV Control = Auto. When EXV Control =
Manual, the position set point will be changeable.
