The “Function Selection” function regulates the controller for heating

and cooling and compares the current room temperature against the

set value. If the current value is lower than the target value for the

energy level “Comfort” heating, the heating controller is activated.

If the current room temperature is higher than the set value for the

energy level “Comfort” cooling, the cooling controller is activated.

Simultaneous heating and cooling is not possible.

Ventilation

In summer, natural cooling at night helps reduce energy

consumption: The night cooling program switches on the room

ventilation system and ventilates the ofﬁ ces using cool external air.

This removes heat from the building at night so that less energy is

required to cool the room the following day. For electrically operated

windows, these can also be used for automatic night cooling in

summer.

Load optimisation

Communication between systems for automation of energy

centres and systems for the generation and distribution of heating

and cooling water enables needs-based adjustment of the ﬂ ow

temperatures. This allows transfer losses to be minimised and the

overall effectiveness of the systems to be increased.

Air quality regulation

Depending on the measured air quality, the volume ﬂ ow

controller is used to introduce more or less fresh air into the room.

If the air quality is good, air intake is reduced to a minimum volume

ﬂ ow. The central air conditioning unit for ventilation automatically

adjusts the level of ventilation based on the data communicated

between the room automation system and the primary systems. This

reduces the energy consumption of the fans by up to 45 %. In the

event of zero occupancy, the volume ﬂ ow is reduced to a minimum.
