25.2. Freezing prevention control

 1. Operation

During cooling mode operation, after 9 minutes have passed since the compressor turned on, the outdoor units stops operating
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 unit. (The remote control unit 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.
(If the outdoor unit stops even though the temperature is 15°C or higher, restart prevention control will activated and the outdoor
unit will not start again for 3 minutes.)
(The 9-minute countdown is cleared while the compressor is stopped.)

(The above illustration shows the operation when there are no conditions for turning the outdoor unit off other than freezing
prevention.)
