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”:

(or

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 Konnex 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.
If the controller is connected to the bus, the room temperature can be transmitted and
received via bus. In addition to the room zone, the controller must have a valid device
address set.
With default address 255, there will be no communication via bus.
If the room temperature is acquired directly at the device, it will be transmitted in the
heating circuit’s room zone (geographical zone (apartm.)) via bus so that it will become
available to all devices on the bus.
The room temperature can also be acquired by bus-compatible room sensors or room
units (e.g. QAW740) and be sent directly via bus. The associated room zone (geo-
graphical zone (apartm.)) is to be set at the sensor or room unit.
