Central ventilation units AIR1 XH
The room temperature can be adapted when the outside temperature rises. For example, a slightly higher room tem-
perature may be acceptable at higher outside temperatures, or a slightly lower room temperature in cooler weather
conditions. This function is used to conserve energy.
The room temperature setpoint is compensated for depending on the outdoor temperature using a control curve with
8 points.
