ClimaDry Sequence Of Operation There are five operational inputs for single stage units A heat pump equipped with ClimaDry can operate and seven operational inputs for two stage units: in three modes; cooling, cooling with reheat, and -Fan Only heating. The cooling/heating modes are like any other -1st Stage Cooling ClimateMaster WSHP. The reversing valve (“O” signal) -2nd Stage Cooling is energized in cooling, along with the compressor -1st Stage Heating contactor(s) and blower relay. In the h

Flushing/Purging Units with ClimaDry Units equipped with ClimaDry must be flushed/purged Under extreme circumstances this procedure may be with a flush cart. Detailed general flushing /purging required multiple times to purge all air from the circuit. instruction can be found in the Flow Controller III IOM. After completing the flushing/purging procedure, restore The unit must be powered (but not operating) during the red wire to the ACC1 ‘N.O.’ terminal on the DXM for flushing/purging.
