Outline of specifications
(1) In heating operation, the upper limit of the fan tap is set by
one with higher temperature of TC2 sensor and TCJ sensor.
• When B zone has continued for 6 minutes, the operation
shifts to C zone.
• In defrost time, the control point is set to +6°C.
(1) In cooling operation, the air conditioner operates as de-
scribed below based upon temp. detected by TC1, TC2 and
TCJ sensors.
To prevent the heat exchanger from freezing, the operation
stops.
• When “J” zone is detected for 5 minutes, the forced
thermo is OFF.
• In “K” zone, the timer count is interrupted, and held.
• When “

mode until it reaches the “
IIIII
” zone.
It is reset when the following conditions are satisfied.
Reset conditions
1) TC1 > 12°C and TC2 > 12°C and TCJ > 12°C
2) 20 minutes passed after stop.
(2) In 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 forced
thermo is 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 TC2 > 12°C and TCJ > 12°C
2) 20 minutes passed after stop.
