CXM Control Start-up Operation

The control will not operate until all inputs and safety

controls are checked for normal conditions. The

compressor will have a 5 minute anti-short cycle delay

at power-up. The ﬁrst time after power-up that there is a

call for compressor, the compressor will follow a 5 to 80

second random start delay. After the random start delay

and anti-short cycle delay, the compressor relay will

be energized. On all subsequent compressor calls, the

random start delay is omitted.
