Room influence
(750, 1050, 1350) The flow temperature is calculated using the heating curve as a factor of the out-
side temperature. This type of control assumes that the heating curve is set cor-
rectly, since the control does not take any room temperature into consideration in
this setting.
Note: However, if there is a RGTF or RGB room unit is connected and the setting
"room influence" is set between 1 and 99%, the deviation of the room tempera-
ture compared to the set point is recorded and taken into consideration in the
temperature control. In this way existing external heat can be considered and a
constant room temperature is possible. The influence of the deviation can be set
in percentage. The better the leading room is (correct room temperature, correct
installation location, etc.), the higher the value can be set and the room tempera-
ture is taken into consideration even more.
Caution! Open radiator valves!
Should there be radiator valves in the leading room (assembly location of the
room sensor), these have to be fully opened.
- Setting for weather compensation with room influence: 1% - 99%
- Setting for pure weather compensation: - - - %
- Setting for pure room compensation: 100%
Room temp limitation
(760, 1060, 1360) The heating circuit pump will be switched on or off, depending on the room tem-
perature due to the switching difference set here. The switch-off point of the
pump is set as difference to the set room set point. The switch-on point of the
point is located 0.25°C below the set room set point. This function is only possible
with the RGT/ RGTF or RGB room unit and active room influence.
A room sensor must be connected. This function only applies to pumped heating
circuits.
