▪ No DHW
No tank installed.
▪ EKHWS/E
Tank with booster heater installed at
the side of the tank.
▪ EKHWP/HYC
Tank with optional booster heater
installed at the top of the tank.
Emergency
When the heat pump fails to operate, the backup heater and/or
booster heater can serve as an emergency heater and either
automatically or non-automatically take over the heat load.
▪ When auto emergency is set to Automatic and a heat pump failure
occurs:
▪ For EHVH/X: The backup heater will automatically take over the
heat load and domestic hot water production
▪ For EHBH/X: The backup heater will automatically take over the
heat load, and the booster heater in the optional tank will
automatically take over the domestic hot water production.
▪ When auto emergency is set to Manual and a heat pump failure
occurs, the domestic hot water and space heating operation will
stop and need to be recovered manually. The user interface will
then ask you to confirm whether the backup heater and/or booster
heater can take over the heat load or not.
We recommend to set Emergency to Automatic if the house is
unattended for longer periods.

▪ 0: Manual
▪ 1: Automatic
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.

▪ 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
▪ a: Additional LWT zone: Highest
temperature
▪ b:
Main
LWT
zone:
Lowest
temperature
CAUTION
If there are 2 zones, it is important that 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. Not configuring the
system in this way could cause damage to the heat
emitters.
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.

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.
▪ A 6V model can be set to 230V, 1ph or 230V, 3ph.
▪ For a 9W model, it is fixed to 400V, 3ph.
