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.’.
Inuence
‘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 dierence 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.
