Menu 3.1.1.1.x - Cooling relative start
Definition
This value determines when cooling must start in relation to the relative tempera-
ture. Low value = narrow temperature regulation range, leading to a comfortable
indoor climate. High value = wider temperature regulation range, which provides
cooling energy savings. Lower and upper limit is shown in the display.
Example
If the required room temperature is 21°C, and Cooling Rel. start in the indoor air
quality level menu is set to 3 K, the cooling unit will begin to operate on a warm
day when the temperature exceeds 21°C + 3 K = 24°C.
Menu 3.1.1.1.x - Heating relative start
Definition
This value determines when the heating coil must start in relation to the relative
temperature. Low value = narrow temperature regulation range, leading to a com-
fortable indoor climate. High value = wider temperature regulation range, which
saves energy because of lower heating requirements. Lower and upper limit is
shown in the display.
Example
If the required room temperature is 21°C, and Heating Rel. start in the indoor air
quality level menu is set to -3 K, the heating coil will begin to operate on a cold
day when the temperature falls below 21°C - 3 K = 18°C.
Menu 3.1.1.1.x - Cooling absolute start
Definition
This value determines when cooling must start in relation to the absolute tempera-
ture. Lower and upper limits are shown in the display.
