Configuration Wizard: Backup Heater; Configuration Wizard: Main Zone - Daikin Altherma 3 WS Installation Manual

6 Configuration
# Code
[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
a Additional LWT zone: Highest
temperature
b Main LWT zone: Lowest temperature
c Mixing station
NOTICE
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.
NOTICE
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.

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 and maximum capacity must be set on the user interface.
Backup heater type
The backup heater is adapted to be connected to most common
European electricity grids. The type of backup heater can be viewed
but not changed.

Description
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
[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
(a)
[9.3.5] [4-07] 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.

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
▪ 0: Underfloor heating
[2.7] [2‑0C]
▪ 1: Fancoil unit

The setting of the emitter type has an influence on the space heating
setpoint range and the target delta T in heating as follows:
