The setting Emitter type can compensate for a slow or a quick
heating/cooling system during the heat up/cool down cycle. In room
thermostat control, Emitter type influences the maximum
modulation of the desired leaving water temperature, and the
possibility for usage of the automatic cooling/heating changeover
based on the indoor ambient temperature.
It is important to set Emitter type correctly and in accordance with
your system layout. The target delta T for the main zone depends on
it.
# Code Description
[2.7] [2‑0C] ▪ 0: Underfloor heating
▪ 1: Fancoil unit
▪ 2: Radiator
The setting of the emitter type has an influence on the space heating
setpoint range and the target delta T in heating as follows:
Description Space heating setpoint range
0: Underfloor heating Maximum55°C
1: Fancoil unit Maximum65°C
2: Radiator Maximum65°C
Control
Define how the operation of the unit is controlled.
Control In this control...
Leaving water Unit operation is decided based on the leaving
water temperature regardless the actual room
temperature and/or heating or cooling demand
of the room.
External room
thermostat
Unit operation is decided by the external
thermostat or equivalent (e.g. heat pump
convector).
Room thermostat Unit operation is decided based on the ambient
temperature of the dedicated Human Comfort
Interface (BRC1HHDA used as room
thermostat).
# Code Description
[2.9] [C‑07] ▪ 0: Leaving water
▪ 1: External room thermostat
▪ 2: Room thermostat
Setpoint mode
Define the setpoint mode:
▪ Fixed: the desired leaving water temperature does not depend on
the outdoor ambient temperature.
▪ In WD heating, fixed cooling mode, the desired leaving water
temperature:
▪ depends on the outdoor ambient temperature for heating
▪ does NOT depend on the outdoor ambient temperature for
cooling
▪ In Weather dependent mode, the desired leaving water
temperature depends on the outdoor ambient temperature.
# Code Description
[2.4] N/A Setpoint mode
▪ Fixed
▪ WD heating, fixed cooling
▪ Weather dependent
When weather dependent operation is active, low outdoor
temperatures will result in warmer water and vice versa. During
weather dependent operation, the user can shift the water
temperature up or down by a maximum of 10°C.
Schedule
Indicates if the desired leaving water temperature is according to a
schedule. Influence of the LWT setpoint mode [2.4] is as follows:
▪ In Fixed LWT setpoint mode, the scheduled actions consist of
desired leaving water temperatures, either preset or custom.
▪ In Weather dependent LWT setpoint mode, the scheduled
actions consist of desired shift actions, either preset or custom.

Control
The control type is displayed here, but cannot be adjusted. It is
determined by the control type of the main zone. For more info about
the functionality, see "6.2.5Configuration wizard: Main zone"[430].
# Code Description
[3.9] N/A ▪ 0: Leaving water if the control type
of the main zone is Leaving water.
▪ 1: External room thermostat if the
control type of the main zone is
External room thermostat or Room
thermostat.
Schedule
Indicates if the desired leaving water temperature is according to a
schedule. Also see "6.2.5Configuration wizard: Main zone"[430].
# Code Description
[3.1] N/A ▪ 0: No
▪ 1: Yes
6.2.7 Configuration wizard: Tank
Heat up mode
The domestic hot water can be prepared in 3 different ways. They
differ from each other by the way the desired tank temperature is set
and how the unit acts upon it.
# Code Description
[5.6] [6-0D] Heat up mode
▪ 0: Reheat only: Only reheat
operation is allowed.
▪ 1: Schedule + reheat: The domestic
hot water tank is heated according to a
schedule and between the scheduled
heat up cycles, reheat operation is
allowed.
▪ 2: Schedule only: The domestic hot
water tank can ONLY be heated
according to a schedule.
