The relationship between the main room temperature, the main set temperature,
and the operation mode is described below, with examples.
(Two examples are given, as the operation differs for temperature differences 2
°
C
and below and 3
°
C
and above.)
The controls are implemented when the control conditions are satisfied, every 5
minutes from the time the power is turned on.
< Implementation conditions when the temperature difference is 2
°
C
or lower.>
