Timer Operation - Mitsubishi Electric SRK19CIS Technical Manual

4.6 TIMER operation

( 1 ) Comfortable TIMER setting (ON TIMER)
If the TIMER is set at ON when the operation select switch is set at the cooling, or the cooling in auto mode operation is selected, the
comfortable TIMER starts and determines the starting time of next operation based on the initial value of 15 minutes and the relationship
between the room temperature at the setting time (temperature of room temperature sensor) and the setting temperature. (Max. 60
minutes)
Operation mode
3 < Room temp. – Setting temp.
At cooling
Notes (1) At 5 minutes before the ON TIMER time, operation starts regardless of the temperature of the room temperature sensor (Th1).
(2) This function does not actuate when the operation select switch is set at the dry as well as the dry in the auto mode.
However, the operation of item (1) above is performed during the dry in the auto mode.
(3) During the comfortable TIMER operation, both the RUN light and TIMER light illuminate and the TIMER light goes off after expiration of the TIMER, ON setting
time.

If the difference (= Room temperature – Setting tempera-
ture) is 4ºC, the correction value is found to be +5 min-
utes from the table shown above so that the starting time
of next operation is determined as follows:
15 min. earlier + 5 min. = 20 min. earlier
