DRCU 2, etc.: Room sensor on the other digital remote control units
Boiler CU: Room sensor on the boiler control unit. Optimally an analogue room control unit should be
placed next to it, because the sensor of the boilerCU can only be used if the boiler CU is
plugged into the wall socket.
Outdoor sensor: Specification of the outdoor sensor assignment to the selected heating circuit
Boiler: Outdoor sensor is connected on the boiler I/O module (plug-in connector 35)
HCM 1: Outdoor sensor is connected on the heating circuit expansion module 1 (terminal 23)
HCM 2, etc.: Outdoor sensor is connected to the additional heating circuit expansion modules
Function: Specifies whether the selected heating circuit is used. If “No” is specified then the sensors
do not need to be connected for the heating circuit and the other settings in this menu are
irrelevant.
Group no: A group is assigned to each heating circuit. The group number is the same as the number of
the heating circuit expansion module to which the shared supply pump for the entire group
is connected.
4.2.10.3 DHWC
Function: Specifies how the selected DHWC is used.
Yes
If a DHWC is present.
No: A DHWC sensor does not need to be installed.
Priority: If the DHWC will be charged with priority at request – all heating circuits in the same group
are switched off.
Group no. Same as point 4.2.10.2
4.2.10.4 Buffer
Function: Specifies how the selected DHWC is used.
No:
If a buffer is not present.
VAR1: Buffer as load-balancing buffer (buffer switched in bypass): The buffer is always charged
from the boiler if the consumers require less heat than is offered by the boiler. The consumers
are supplied by the buffer or by the boiler, depending on which one first provides the required
temperature level.
VAR“: Buffer as central heat accumulator and distributor (buffer switched directly). First the buffer
is heated up to target temperature, before the heat consumers obtain a release.
