1.1.24 Cooling Monitoring Function
Monitoring function is activated while cooling and program dry operation are suspended.
TOF: Compressor recycling guard timer (3-minute timer)
TM1: 5-minute timer
TM2: 4-minute timer
<A> At cooling: Temperature set by wireless remote controller
<B> Temperature set by wireless remote controller + 1 deg. (Cooling operation)
Even if the suction temperature remains in the differential range, a compressor is cycled ON
and OFF.
DETAIL: When the suction temperature rises again to <A> (point b) after the suction
temperature is dropped to <A> and the compressor turns OFF (point a) the 5-minute timer
starts.
After that, when the suction temperature is within the differential range, even after a lapse of 5
minutes, the compressor is forced to turn ON (point c).
When the suction temperature is still in the differential range, after another 4 minutes of
compressor ON, the compressor is forced to turn OFF (point d).
The 5 and 4-minute timers are effective only within the differential temperature range, and when
the air suction temperature is reached to <B> or <A> while the timers are counting, timers are
reset and the compressor is turned ON or OFF.
(Note, however, that function of placing the compressor in a 3-minute compressor recycling
guard timer is provided at point e.)
While the compressor is OFF, the indoor fan operation is controlled by tap A during cooling
mode.
In the program dry mode, the indoor fan starts operating five seconds after the compression
starts, and it stops operating when the compressor shuts down.
