Set optimisation
(not for weather-
dependent control)
The optimisation function allows you to
achieve a certain room temperature at a
desired switching point The display shows how
many minutes earlier the heating has to be
started. This time applies per K of temperature
difference between actual temperature and the
desired setpoint temperature.
Example
:
In the bathroom at 06.00 a change is pro-
grammed from reduction (17 °C) to comfort
temperature (23 °C).
Without the optimisation function, the room
thermostat stops heating request for bathroom
at 06.00. Depending on the size of the room
and heating system used, the bathroom reach-
es the desired 23 °C at 06.30, for example.
With a set optimisation of 5 min/K, the
thermostat requests the heating requirement
earlier as follows:
•
Setpoint temperature at 06.00 --> 23 °C
•
Actual temperature --> 17 °C
•
i. e. Delta T = 6 K
•
6 K * 5 min/K = 30 min
The controller starts the heating 30 mins
earlier and reaches the setpoint temperature
at 06.00.
The optimisation value depends on spatial and
heating factors.
