2-6 Condensing Temperature Control (Cooling)
Condensing temperature is controlled by the outdoor heat exchanger coil temperature as
sensed by sensor C2.
Chart Explanations and notes
This chart shows how the outdoor fan speed and the electronic refrigerant control valve
react to coil temperature to control condensing temperature.
Sensor C2 is located in the middle of the outdoor unit heat exchange coil.
When C2 rises above 140°F the electronic refrigerant control valve opens at 50 steps/30
seconds, and the outdoor fan speed is forced to change to high (H) until C2 falls below
131°F.
