Misleading But Good Operations - Toshiba RAS-10SK-E x2 Service Manual

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. Operation of air-conditioner
1 When the power plug or the power cord
of the indoor unit is inserted, the OPERA-
TION lamp on the setting indication part
flashes.
2 Fan speed remains unchanged in the dry
mode.
3 Room temperature is in the range under
which the compressor is turned off, but
the compressor will not stop.
4 The compressor will not switch on or off
even when the thermo control is oper-
ated in the dry operation.
5 Compressor does not work though room
temperature is in the range of turning the
compressor on.
6 During automatic operation, the opera-
tion mode changes.
7 When the power is turned on, the opera-
tion starts automatically.
Table 9-1-1
The OPERATION lamp flashes, indicating that power is turned
on. If this happens, push the START/STOP button once to cause
the lamp to stop flashing. A power outage also causes the lamp
to flash.
Fan speed is automatically controlled in the dry mode.
The compressor will not stop while the compressor on hold timer
(3-minutes timer) is actuated.
In the dry mode, the compressor goes on and off at regular inter-
vals, independent of the thermo control.
Compressor does not work while the compressor restart delay
(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 contin-
ues for 15 min. according to the room temperature. And after
selection of the dry operation, the condition of the room tempera-
ture 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.
