Chart Summary and Explanations

Discharge temperature is sensed by TH8 (discharge gas sensor).

When the temperature rises above 203°F (24, 36 Type) the electronic refrigerant control
valve opens at 50 steps/30 seconds until the temperature falls below 200°F (24, 36 Type) .

During HEATING operation, when the temperature rises above 221°F (24, 36 Type), the
control circuit stops the outdoor fan motor until the temperature falls below 194°F (24, 36
Type). Please note that this control does not function during COOLING operation.

For both COOLING and HEATING modes, if the temperature reaches 239°F (24, 36 Type)
the operation shuts down and alarm P3 appears on the remote controller.

The outdoor fan speed is controlled on discharge temp. at heating mode.
