Menu 3.1.1.1.x - Absolute / Relative temperature
Definition Used to select supply air or room temperature in relation to either absolute or rela-
tive temperature.
Absolute - Specify start temperature for heating coil or cooling unit.
Relative - Permitted temperature changes relative to the heating coil or cooling
unit start temperature. See how the temperature variation follows when the set
point is altered (diagram below, dotted lines).
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.
