Configuration wizard: Backup heater

INFORMATION
▪ For models with integrated backup heater (3V models),
most of the backup heater settings are fixed.
▪ For other models, the backup heater settings are only
applicable in case the optional external backup heater
kit is installed.
The backup heater is adapted to be connected to most common
European electricity grids. If the backup heater is available, the
voltage, configuration and capacity must be set on the user
interface.
The capacities for the different steps of the backup heater must be
set for the energy metering and/or power consumption control
feature to work properly. When measuring the resistance value of
each heater, you can set the exact heater capacity and this will lead
to more accurate energy data.
Backup heater type
▪ For models with integrated backup heater, this is fixed to 3V.
▪ For other models, this can be set to No heater, or External
heater (i.e. when the optional external backup heater kit is
installed).
# Code
[9.3.1] [E‑03] ▪ 0: No heater
▪ 1: External heater
▪ 2: 3V
Voltage
▪ For a 3V model, this is fixed to 230V, 1ph.
▪ The optional external backup heater can be set to 230V, 1ph or
400V, 3ph.
# Code
[9.3.2] [5‑0D] ▪ 0: 230V, 1ph
▪ 2: 400V, 3ph
Configuration
The backup heater can be configured in different ways. It can be
chosen to have a 1-step only backup heater or a backup heater with
2 steps. If 2 steps, the capacity of the second step depends on this
setting. It can also be chosen to have a higher capacity of the
second step in emergency.
▪ For a 3V model, this is fixed to Relay 1.
▪ The optional external backup heater can be set to the following:
# Code
[9.3.3] [4‑0A] ▪ 0: Relay 1
▪ 1: Relay 1 / Relay 1+2
▪ 2: Relay 1 / Relay 2
▪ 3: Relay 1 / Relay 2 Emergency Relay
1+2
INFORMATION
Settings [9.3.3] and [9.3.5] are linked. Changing one
setting influences the other. If you change one, check if the
other is still as expected.

Description
INFORMATION
During normal operation, the capacity of the second step of
the backup heater at nominal voltage is equal to
[6‑03]+[6‑04].
INFORMATION
If [4‑0A]=3 and emergency mode is active, the power
usage of the backup heater is maximal and equal to
2×[6‑03]+[6‑04].
Capacity step 1
# Code
[9.3.4] [6‑03] ▪ The capacity of the first step of the
backup heater at nominal voltage.
Additional capacity step 2
Restriction: Only applicable in case the external backup heater kit
is installed.
# Code
[9.3.5] [6‑04] ▪ The capacity difference between the
second and first step of the backup
heater at nominal voltage. Nominal
value depends on backup heater
configuration.

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
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
[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
