2. In all cooling operation, the air conditioner operates
as described below based upon temp. detected by
TC2 and 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.

operation returns to normal operation.
( ) value:
When the power supply is
turned on, the forced
thermostat becomes OFF if
the temperature is less than
this indicated temperature.
1.
In heating operation, the higher temperature of TC2
sensor
and TCJ sensor is compared with temperature
of TC1 sensor
and then the lower temperature is
used
to
set the upper limit of the fan tap.
• When B zone has continued for 6 minutes, the
operation
shifts to C zone.
• In defrost time, the control point is
set to
+10.8 ˚F
[+6˚C]
