Samson TROVIS 5500 - Optimization

EB 5573-1 EN 81
Functions of the heating circuit
With an activated room sensor, the measured room temperature is displayed when the re-
mote operation is connected and activated. Nevertheless, it is not used for control when ei-
ther the optimization, adaptation or ash adaptation function is activated.

6.9 Optimization
This function requires the use of a room sensor. Depending on the building characteristics,
the controller determines and adapts the required advance heating time (maximum 8 hours)
to ensure that the desired 'Day set point' (rated room temperature) has been reached in the
reference room when the time-of-use starts. During the advance heating period, the controller
heats with the max. ow temperature. This temperature is built up in steps of 10°C. As soon
as the 'Day set point' has been reached, weather-compensated control is activated.
Depending on the room sensor, the controller switches off the heating system up to one hour
before the time-of-use ends. The controller chooses the deactivation time such that the room
temperature does not drop signicantly below the desired value until the time-of-use ends.
During the advance heating period and the premature deactivation of the heating system, the
or icon blink on the display.
Outside the times-of-use, the controller monitors the 'Night set point' (reduced room tempera-
ture). When the temperature falls below the night set point, the controller heats with the max.
ow temperature until the measured room temperature exceeds the adjusted value by 1°C.
