ORS regulation
ORS regulation refers to Outdoor air temperature-Related Supply
air temperature regulation. This means that the temperature of
the supply air is regulated in relation to the temperature of the
outdoor air.
An individually adjusted curve regulates the ratio between the
supply air and the outdoor air temperature. The curve has four
adjustable breakpoints.

ORE regulation
ORE regulation refers to Outdoor air temperature-Related Extract
air temperature regulation. This means that the extract air tem-
perature is regulated in relation to the outdoor air temperature.
An individually adjusted curve regulates the ratio between the
extract air and the outdoor air temperature. The curve has four
adjustable breakpoints.

X = Outdoor air temperature °C
Example:
If the outdoor air temperature is under -30 °C (X1), the supply
air temperature set point will constantly be 18 °C (Y1).
If the outdoor air temperature is between -30 °C (X1) and -10
°C (X2), the supply air temperature set point is regulated from
18 °C (Y1) up to 20 °C (Y2) as shown in the curve.
If the outdoor temperature is between -10 °C (X2) and +10 °C
(X3) the supply air set point will constantly be 20 °C (Y3).
If the outdoor air temperature is between +10 °C (X3) and +30
°C (X4), the supply air temperature set point is regulated from
20 °C (Y3) down to 18 °C (Y4) as shown in the curve.
If the outdoor air temperature is over 30 °C (X4), the supply air
temperature set point will constantly be 18 °C (Y4).
