Voltage
Depending on how the backup heater is connected to the grid and
what voltage is supplied, the correct value needs to be set. In either
configuration, the backup heater will operate in steps of 1 kW.
# Code Description
[9.3.2] [5‑0D] ▪ 0: 230V, 1ph
▪ 2: 400V, 3ph
Maximum capacity
During normal operation the maximum capacity is:
▪ 3 kW for a 230 V, 1N~ unit
▪ 6 kW for a 400 V, 3N~ unit
The maximum capacity of the backup heater can be limited. The set
value depends on the used voltage (see table below) and is then the
maximum capacity during emergency operation.
# Code Description
[9.3.5] [4-07]
(a)
0~6 kW when voltage is set to 230 V,
1N~
0~9 kW when voltage is set to 400 V,
3N~
(a)
If the value [4-07] is set lower, then the lowest value will be used
in all operation modes.
7.2.5 Configuration wizard: Main zone
The most important settings for the main leaving water zone can be
set here.
Emitter type
Heating up or cooling down the main zone can take longer. This
depends on:
▪ The water volume of the system
▪ The heater emitter type of the main zone
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 Maximum 55°C
1: Fancoil unit Maximum 65°C
2:
Radiator
Maximum 65°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:

▪ 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.
# Code Description
[2.1] N/A ▪ 0: No
▪ 1:
