9-1-3. Misleading but Good Operations
(Program Controlled Operation)
The microcomputer performs the operations listed in
Table 9-1-1 to control the air conditioner. If a claim is
made on the operation, check whether it corresponds
to the contents in the Table 9-1-1. If it does, it is an
indispensable operation for the control and mainte-
nance of the air conditioner: it is not a failure of the
unit.
No.

In the dry mode, the compressor goes on and off at regular
intervals, independent of the thermo control.

(3-min.) timer is active. The same is true after power is turned
on, as the time is still active.
After selection of the cooling and dry operation, the operation
mode is selected again when the compressor off mode continues
for 15 min. according to the room temperature. And after selection
of the dry operation, the condition of the room temperature which
is Room temp. ≥Set temp.+1 and which is Room temp.<Set
temp.–4 continues for 15 min., the operation mode is selected
again.
When the auto restart controlling is selected, the operation is
performed automatically in the previous operation mode after
the power supply has been turned on.
