Compressor Run/Off Timing in Different Cooling Modes
a) Low Cool Mode
– In this mode, cooling is in intermittent operation. Cooling is active for 10 minutes and stops for 3
minutes in every 13 minutes timing interval. Compressors are alternated in a way that at least one compressor in the
unit is running for 10 minutes for every 13 minutes interval. There will be off timing of 3 minutes after each cooling
operation of 10 minutes.
b) Medium Cool Mode
– Cooling operation is continuous in this mode. Each compressor will have run timing of 10
minutes and off timing of 3 minutes. Both compressors will operate at the same time in the first 2 minutes and the last
5 minutes in each 13 minutes interval. There will then be 2 compressors running for a total of 7 minutes in each cooling
operation of 13 minutes.
c) High Cool Mode
– In this mode, cooling operation is also continuous. One compressor will always be active while the
other compressor will operate intermittently – running for 13 minutes and off timing of 5 minutes in each 18 minutes
interval. Both compressors will then be in continuous operation for a total of 13 minutes in each 18 minutes interval.
The control is having a compressor run time equalization function. After each cooling cycle, the compressor with the least
run time will operate as the lead compressor.
