Functions of the heating circuit
6.1
Outdoor temperature-dependent advance heating
Only selectable for systems Anl 1 to 3 with Co5 -> Fb13 = ON.
The controller switches the heating on before the time-of-use starts in normal operation depend-
ing on the outdoor temperature. The
Advance heating time is based on an outdoor temperature
of –12 °C. The advance heating time is shortened in case of higher outdoor temperatures.

6.2
Optimization using a room sensor
Only selectable for systems Anl 1 to 3 with Co5 -> Fb13 = ON.
Both the functions described should only be used if the room in which the room sensor is located
(reference room) has a heating characteristic that is similar to the rest of the building.
No thermostat valves should be mounted on the radiators in the reference room.
There are two types of optimization depending on the activation conditions:
4
Outdoor temperature-dependent advance heating, room temperature-dependent deacti-
vation
The controller activates the heating depending on the outdoor temperature before the
time-of-use starts in normal operation. The
Advance heating time is based on an outdoor
temperature of –12 °C. The advance heating time is shorter when the outdoor temperature is
higher (see section 6.1).
4
Room temperature-dependent advance heating and deactivation
The controller calculates the required advance heating time (max. 6 hours) adapted to the
building characteristics, resulting in the
Day set point (rated room temperature) being
reached in the reference room when the time-of-use starts. The heating is heated with the
maximum flow temperature during the advance heating phase. As soon as the
Day set point
is reached, outdoor temperature-dependent control starts.
The controller deactivates the heating in both types of optimization depending on the room sen-
sors up to two hours before the time-of-use finishes.
The controller chooses the deactivation time such in a way that the room temperature does not
drop significantly below the desired temperature until the time-of-use ends.
