1. In heating operation, the upper limit of the fan tap is set according to the lower of
whichever is the higher between TC2 sensor and TCJ sensor temperatures, on
the one hand, and TC1 sensor temperature, on the other.
• If the fan continuously operates in zone B for 6 minutes, it automatically moves
into zone C.
• During defrosting, the control point is shifted by +6°C.

1. During cooling, the air conditioner is operated in the manner described below
according to the temperature readings of the TC1, TC2 and TCJ sensors.
• If zone J operation is detected for 5 minutes, the air conditioner is forced into
thermo OFF.
• In zone K, the timer is put on pause, with the current timer count retained.
• If zone I operation is detected, the timer count is cleared, and the air conditioner
returns to normal operation.
• If continuous zone J operation forces the air conditioner into thermo OFF, the
indoor fan is operated in breeze mode until it moves into zone I.
The control is terminated under the following conditions:
Termination conditions
