7.3.3 Outdoor compensation
If no outdoor sensor is installed, this function will not be available,
and the P No. is not shown. The supply air or room temperature set-
point can be compensated directly by the outdoor temperature. The
compensation, which may be positive or negative, states in °C how
much the supply air or room/return air temperature setpoint is to be
shifted.
There are two curves, one for the summer and one for the winter com-
pensation, see the figure below.
The outdoor compensation is not active on delivery. It is activated by
setting the desired compensation values in the list, P 50 for winter
compensation and P 53 for summer compensation.
The summer compensation starts when the outdoor temperature is
greater than “Start summer compensation”. The maximum com-
pensation is achieved when the outdoor temperature is greater
than or equal to “Stop summer compensation”.
