Samson Trovis 5100 - Manual (Page 47)

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 5.7).
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, weather-compensated 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 that the room temperature does not drop significantly below the desired temperature until
the time-of-use ends.
During the advance heating period and the premature deactivation of the heating system, the
icons
or blink on the display. Outside the times-of-use, the controller monitors the Night
set point (reduced room temperature). When the temperature falls below the night set point, the
controller heats with the max. flow temperature until the measured room temperature exceeds
the adjusted value by 1 °C.
Note!
Direct sunshine can cause the room temperature to increase and thus result in the premature de-
activation of the heating system.
When the room temperature decreases while the heating system is temporarily outside its
times-of-use, this can prematurely cause the controller to heat up to the adjusted Room set point.
