Heating circuit with room sensor
Settings - heating circuit with room sensor
In addition to the basic settings, you can set these
parameters for each heating circuit installed with
a room sensor.
Explanation of [Disregard room temperature]
If the room sensor is in an unsuitable position for
measuring the actual room temperature - next to a
stove, for example - the room sensor can operate at a
constant temperature.
If you set the parameters to [Yes], a room
temperature of 21 °C is used as the basis.
Explanation of [Child safety]
This locks the buttons on the room sensor. If this
function is set to [Yes], neither the temperature nor the
operating condition can be changed any more on the
room sensor.
Explanation of [Calibration value]
If there is a difference between the actual room
temperature and the temperature displayed on the
room sensor, use this parameter to adjust this
difference. After this calibration, the room sensor will
display the corrected room temperature.
A positive (+) or a negative (-) value can be
entered as the corrective value. This value is
added to the currently measured room temperature.
Example:
Measured room temperature = 24 °C
[Calibration value] = -2 °C
=> Displayed temperature on room sensor 22 °C
Explanation of [Background lighting]
This sets the brightness of the background lighting for
the room sensor display. The setting 0% turns the
background lighting off.
Explanation of [Humidity indicator]
This determines whether the currently measured air
humidity in the room is displayed on the room sensor
or not.
Explanation of [Room effect]
Optional: only for room sensor
The flow temperature is calculated on the basis of the
heating curve and the outside temperature. If the room
temperature falls by 1°C, the target flow temperature is
increased by this set value. If the room temperature
rises by 1°C, the target flow temperature is decreased
by the set value.
For underfloor and wall heating with a design
temperature of 30 °C, set the room influence to 1
°C; with a design temperature of 40 °C, set it to 2 °C.
Explanation of [Switch-on diff. room] and [Switch-
off diff. room]
Optional: only for room sensor
These parameters specify the allowed deviation of the
set room temperature for switching the heating circuit
on and off.
Example:
Room temperature setting = 21 °C
[Switch-on diff. room] = 0.5 °C
[Switch-off diff. room] = 2 °C
=> The heating circuit will be switched off as soon as
the room temperature reaches 23 °C (=21 + 2 °C). If
the room temperature falls to 21.5 °C (=21+0.5 °C),
heat is supplied to the heating circuit again.
