Room T limit (room temperature limitation) 3000
This section is only relevant if you have installed a room temperature sensor or room
panel / remote control.
The controller adjusts the desired ow temperature to eliminate the dierence between
the desired and the actual room temperature.
There are two basic principles for control of the room temperature.
A: Max. room temperature limitation
Use this limitation if your heating system is fully equipped with thermostats and you also
want to obtain a max. limitation of the room temperature. The controller will allow for
free heat gains, i.e. solar radiation or heat from a re place, etc.
Inuence
‘Gain - min.’ (min. limitation)
Desired room temperature
Actual room temperature
‘Gain - max.’ (max. limitation)
The ‘Gain - max.’ determines how much the room temperature should inuence the
desired ow temperature.
If the ‘Gain’ is too high and / or the ‘Intgr. time’ too low, there is a risk of unstable control.
Example A1
The actual room temperature is 2 degrees too high.
The ‘Gain - max.’ is set to -4.0.
The ‘Gain - min.’ is set to 0.0.
The ‘Slope’ is 1.8.
Result:
The desired ow temperature is changed by 2 x -4.0 x 1.8 = -14.4 degrees.
