The setpoint increase is used to define by what amount the temperature request (to the
boiler or the primary controller) shall be raised against the flow temperature setpoint.
For detailed information, refer to chapter 15 "Communication".

9.10.2 Acquisition of the room temperature
The room temperature is required for the optimization functions and for influencing the
flow temperature setpoint.
The input is to be activated via "Extra configuration":
Main menu > Commissioning > Extra configuration > Heating circuit 1 (or 2 or 3) > Inputs >
Room sensor Assign terminal
A heating circuit can handle a maximum of 2 room temperatures. In that case, it is of no
importance whether the room temperature is acquired locally or via the KNX bus.
The average will be generated from the 2 actual values.
The type of room temperature sensor can be selected:
Example with input terminal RMH760.X4:
Main menu > Commissioning > Settings > … or
Main menu > Settings > Inputs > RMH760.X4 > Type
The following choices are available:
• LG-Ni 1000
• 2 × LG-Ni 1000
• T1
• Pt1000
• DC 0…10 V
A maximum of 2 LG-Ni 1000 sensors can be connected to the same terminal. This
cannot automatically be identified by the controller. For this reason, in that case,
2 × LG-Ni 1000 sensors must be selected when parameterizing the terminal inputs.
