Maintenance
B: Reference room temperature control
Used if your heating system is not equipped with thermostats and you select the room
with room temperature sensor as a temperature reference for the rest of the rooms.
Set a positive value for the ‘Gain - min.’ and a negative value for the ‘Gain - max.’.
Inuence
‘Gain - min.’ (min. limitation)
Desired room temperature
Actual room temperature
‘Gain - max.’ (max. limitation)
The room temperature sensor in the reference room measures the actual room
temperature.
If a dierence occours between the actual and the desired room temperature, the
desired ow temperature can be corrected. The correction is based on the settings in the
lines 3182 and 3183. This correction of the desired ow temperature will normally give a
correct room temperature. See also line 3015.
Example B1
The actual room temperature is 2 degrees too low.
The ‘Gain - max.’ is set to -3.5.
The ‘Gain - min.’ is set to 2.0.
The ‘Slope’ is 1.8.
Result:
The desired ow temperature is changed by 2 x 2.0 x 1.8 = 7.2 degrees.
Example B2
The actual room temperature is 2 degrees too high.
The ‘Gain - max.’ is set to -3.5.
The ‘Gain - min.’ is set to 2.0.
The ‘Slope’ is 1.8.
Result:
The desired ow temperature is changed by 2 x (-3.5) x 1.8 = -12.6 degrees.
