Indoor Coil Overheat Protection - GE AZ45E07EA Series Technical Service Manual

Indoor Coil Overheat Protection

Heat Pump Operation
The Overheat Protection is only on the AZ6500 series.
The Overheat Protection system protects the Zoneline from overworking when the outdoor temperature is
too high for heat pump operation. The temperature of the indoor coil is monitored and if it rises above 131°F,
the control stops the outdoor fan. The Zoneline will resume normal operation when the coil temperature is
less than 122°F.
