Outline of specifications
1. In all cooling operation, the air conditioner operates
as described below based upon temp. detected by
TC1, TC2 and TCJ sensors.
• When “J” zone is detected for 5 minutes, the
thermostat is forcedly off.
• In “K” zone, the timer count is interrupted, and held.
• When “
I ” zone is detected, the timer is cleared
and the operation returns to the normal operation.
• If “J” zone continues, operation of the indoor fan in
LOW mode continues until it reaches the “
I ” zone.
It is reset when the following conditions are satisfied.
Reset conditions
1) TC1 ≥ 12˚C and TCJ ≥ 12˚C
2) 20 minutes passed after stop.

TC1: Temperature of indoor
heat exchanger sensor
2. In all cooling operation, the air conditioner operates
as described below based upon temp. detected by
TCJ sensors.
• When “M” zone is detected for 45 minutes, the
thermostat is forcedly off.
• In “N” zone, the timer count is interrupted and held.
• When shifting to “M” zone again, the timer count
restarts and continues.
• If “L ” zone is detected, the timer is cleared and the
operation returns to normal operation.
Reset conditions
1) TC1 ≥ 12˚C and TCJ ≥ 12˚C

1. In heating operation, the lowest temperature between
TC1 sensor and the highest temperature between
TC2 and TCJ sensor is set as the upper bound of the
fan speed mode control.
• When B zone has been continuing for 6 minutes,
the operation shifts to C zone.
• For the defrosting operation, the control point is
set to +6˚C.
