Water Pump
The water pump will on if compressor is on during cooling cycle. The pump will remain on for at least 5 minutes after the
compressor is off.
During mode change from cooling to non-cooling mode, the pump will on for minimum 5 minutes. During defrost cycle,
the pump will on and will on for another 5 minutes once the defrost cycle is terminated.
Water level Switch
This normally close switch is to detect faults in water pump system. It will confirm for 30 seconds for switch open and 60
seconds for switch close.
Once switch is confirmed open, it will force compressor to cut off. If the switch is closed within 5 minutes, the compressor
is allowed to cut in. If the switch does not close for more than 5 minutes, the system will warn user regarding the fault,
the compressor is not allowed to cut in. If the switch is confirmed opened twice within 30 minutes, the system assumes
there are faults.
