INFORMATION
The auto emergency setting can be set in the menu
structure of the user interface only.
INFORMATION
If [4‑03]=1 or 3, then
Emergency
=
Manual
is not applicable
for the booster heater.
INFORMATION
If a heat pump failure occurs and Emergency is set to
Manual
, the room frost protection function, the underfloor
heating screed dryout function, and the water pipe
antifreeze function will remain active even if the user does
NOT confirm emergency operation.
Number of zones
The system can supply leaving water to up to 2 water temperature
zones. During configuration, the number of water zones must be set.
# Code Description
[4.4] [7‑02] ▪ 0: Single zone
Only one leaving water temperature
zone:
a
a Main LWT zone
[4.4] [7‑02] ▪ 1: Dual zone
Two leaving water temperature zones.
The main leaving water temperature
zone consists of the higher load heat
emitters and a mixing station to
achieve the desired leaving water
temperature. In heating:
a
b
c
a Additional LWT zone: Highest
temperature
b Main LWT zone: Lowest temperature
c Mixing station
CAUTION
NOT configuring the system in the following way can cause
damage to the heat emitters. If there are 2 zones, it is
important that in heating:
▪ the zone with the lowest water temperature is
configured as the main zone, and
▪ the zone with the highest water temperature is
configured as the additional zone.
CAUTION
If there are 2 zones and the emitter types are wrongly
configured, water of high temperature can be sent towards
a low temperature emitter (underfloor heating). To avoid
this:
▪ Install an aquastat/thermostatic valve to avoid too high
temperatures towards a low temperature emitter.
▪ Make sure you set the emitter types for the main zone
[2.7] and for the additional zone [3.7] correctly in
accordance with the connected emitter.
NOTICE
An overpressure bypass valve can be integrated in the
system. Keep in mind that this valve might not be shown
on the illustrations.
5.2.4 Configuration wizard: Backup heater
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.
Voltage
▪ For a 3V model, this is fixed to 230V, 1ph .
▪ For a
6V
model, this can be set to:
▪ 230V, 1ph
▪ 230V, 3ph
▪ For a
9W
model, this is fixed to
400V, 3ph
.
# Code Description
[9.3.2] [5‑0D] ▪ 0: 230V, 1ph
▪ 1:
230V, 3ph
▪ 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.
# Code Description
[9.3.3] [4‑0A] ▪ 0: Relay 1
▪ 1: Relay 1 / Relay 1+2
(a)
▪ 2: Relay 1 / Relay 2
(a)
▪ 3: Relay 1 / Relay 2 Emergency Relay
1+2
(a)
(a) Not available for 3V models.
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.
INFORMATION
During normal operation, the capacity of the second step of
the backup heater at nominal voltage is equal to
[6‑03]+[6‑04].
