26.2. Freezing prevention control
1. Operation
During cooling mode operation, after 9 minutes have passed since the compressor turned on, the outdoor unit will stop its
operation when the temperature detected by the indoor unit pipe temperature sensor is 2°C or lower.
The indoor unit continues operating at the fan speed set by the remote control. (The remote control display does not change.)
2. Cancelling
This control is cancelled when the temperature detected by the indoor unit pipe temperature sensor is 15°C or higher, however
3 minutes waiting of prevention control is necessary.
(The 9 minutes countdown is cleared while the compressor is stopped.)
(The above illustration only shows the operation stops due to freezing prevention control of the indoor pipe temperature sensor.)
