Weather-dependent operation
The unit operates 'weather dependent' if the desired leaving water or tank
temperature is determined automatically by the outdoor temperature. It therefore
is connected to a temperature sensor on the North wall of the building. If the
outdoor temperature drops or rises, the unit compensates instantly. Thus, the unit
does not have to wait for feedback by the thermostat to increase or decrease the
temperature of the leaving water or tank. Because it reacts more quickly, it
prevents high rises and drops of the indoor temperature and water temperature at
tap points.
Advantage
Weather-dependent operation reduces energy consumption.

Weather-dependent curve

To be able to compensate for differences in temperature, the unit relies on its
weather-dependent curve. This curve defines how much the temperature of the
tank or leaving water must be at different outdoor temperatures. Because the
slope of the curve depends on local circumstances such as climate and the
insulation of the house, the curve can be adjusted by an installer or user.
Availability
The weather-dependent curve is available for:
▪ Main zone - Heating
▪ Main zone - Cooling
▪ Additional zone - Heating
▪ Additional zone - Cooling
▪ Tank
