Operations
Low Pressure Protection
With the compressor running, if the low pressure switch opens for 1 minute, the compressor will stop.
If this condition occurs 3 times in an hour, the compressor will lock out and a low pressure error code will be displayed at the
indoor unit.
If the compressor is not running and the switch opens for 30 seconds, a low pressure error code will be displayed.
The low pressure switch does not stop compressor operation or signal an error code during the following conditions:
The rst 8 minutes of run time when the compressor starts a new cycle
During defrost
When the ambient temperature is below 32°F/0°C
Following the termination of an oil return cycle
When any of the above 4 conditions are present, low pressure protection is provided by the coil temperature sensors in both
heating (Te) and cooling (Tc2) modes.
