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
+10.8°F[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.

• 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
