OPERATION

Unit Cooling Mode

Once the indoor ambient temperature rises past the cool demand threshold (Cool Set Point + 1.5 ˚F) (see gure below), and the

compressor is not locked out, the cooling cycle begins. As shown in the gure below, the fan is started 5 seconds prior to the

compressor. Once the indoor ambient temperature has been lowered to the cool set point (Cool Set Point minus .25 ˚F), the cooling

cycle starts to terminate by shutting off the compressor. After a 30 seconds delay, the fan is shut off. (See gure below for graphic

details)
