Outline
In order to ensure the dependability of the compressor, the compressor must be stopped according
to the conditions of the temperature of the outdoor air and outdoor heat exchanger.
Detail
Operation stops depending on the outdoor air temperature
Compressor operation turns OFF under the conditions that the system is in cooling operation and
outdoor air temperature is below 10.4°F(–12°C).
NOTE: See Page 42 for low-ambient cooling operation setting.
3.10 Defrost Control
Outline
Defrosting is carried out by the cooling cycle (reverse cycle). The defrosting time or outdoor heat
exchanger temperature must be more than its fixed value when finishing.
Detail
Conditions for Starting Defrost
Certain conditions must exist when starting the defrost operation. The heat exchanger must be in
heating operation, 6 minutes should elapse after the compressor is started, and more than 38
minutes of accumulated time should pass after the start of operation or ending of the last defrosting
operation.
Conditions for Canceling Defrost
The judgment must be made with heat exchanger temperature.
(39.2~64.4°F / 4~18°C)
