Direct Room Temperature Compensation

With direct room temperature compensation (in case of no heating curve adaptation) the mixed water temperature setpoint will be adjusted by the deviation of the room temperature multiplied by the direct room temperature compensation factor, as defined by the parameter RMT-01. See next figure.

One K of room temperature setpoint deviation will cause RMT-01 room temperature compensation of mixed water temperature setpoint. The parameter HCA-04 has to be set to the value "0" (room influenced, no adaption).

Fig. 4.   Room temperature compensation

For radiator or under-floor heating a moderate influence of the room temperature compensation of the mixed water temperature setpoint is sufficient e.g. 4 K.

In case of rooms with many people inside, a lot of un-controllable heating energy is emitted (60 - 120 W / individual). A pure outside air compensated mixed water temperature setpoint does not lead to a good comfort. The same happens in case of rooms with a lot of electronic equipment heating up the room.

In this case the room compensation factor has to be significantly higher e.g. 10 K.
