Siemens Modular Heating Controller RMH760B CE1P3133en
Building Technologies 9 Heating circuit control 2017-09-29
The RMH760B has no Comfort setpoint "Cooling". The impact on the Comfort setpoint
"Cooling" as described above is only possible in connection with a room control
combination. For more detailed information, refer to subsection 9.10.3 "Room control
combination".
The setpoint shift is limited by the setpoints for Protection mode. Also refer to the graph
above.
The Precomfort setpoints
are shifted also:
Hence, the current Precomfort setpoint "Heating" is calculated as follows:
Precomfort setpoint "Heating" + ("Remote setpoint" minus Comfort setpoint "Heating")
And the current Precomfort setpoint "Cooling" is calculated as follows:
Precomfort setpoint "Cooling" + ("Remote setpoint" minus Comfort setpoint "Heating")
The note above in paragraph "Comfort " also applies analogously to the Precomfort
setpoint.
The Economy setpoints
are shifted only if, otherwise, the Precomfort setpoints would
lie outside the Economy setpoints. Also refer to the graph above.
The input is to be activated via "Extra configuration":

The range set here must accord with the scale of the remote setpoint adjuster. The
factory settings are matched to the BSG21.1 remote setpoint adjuster and must not be
changed with this type of setpoint adjuster.
• It is not recommended to use a QAA25 room temperature setpoint adjuster since its
characteristic is not linear so that setpoint deviations of maximum 1 K would occur.
Compensation is not possible
• DC 0…10 V setpoint adjusters cannot be connected. The input is ready
preconfigured for 0…1,000 Ω
• The adjusted setpoint represents the Comfort setpoint. At the same time, the
Precomfort setpoint is displaced parallel so that the difference between the 2
setpoints will be maintained
9.4.4 Room temperature setpoint adjuster, relative
For room temperature setpoint readjustments in the Comfort and Precomfort modes, a
remote setpoint adjuster (e.g. QAA27 with room temperature sensor) can be configured.
The input is to be activated via "Extra configuration":
Main menu > Commissioning > Extra configuration > Heating circuit 1 (or 2 or 3) > Inputs >
Room setpoint adjuster rel Assign terminal
There are no settings required.
