Comfortable Timer Setting; Sleep Timer Operation - Mitsubishi Heavy Industries SRK20ZD-S1 Technical Manual

(6) Comfortable timer setting

If the timer is set at ON when the operation select switch is set at the cooling or heating, or the cooling or heating 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
3 < Setting temp. – Room temp.
At heating
Notes (1) At 5 minutes before the timer ON time, operation starts regardless of the temperature of the room temperature sensor (Th1).
(2) This function does not operate when in the Dry or Auto Dry and FAN mode.
However, the operation in item (1) does operate in the Auto Dry and FAN 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.
