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.
