Configuration Wizard: Backup Heater; Configuration Wizard: Main Zone - Daikin EGSAH10UDA9W Installation Manual

6 Configuration
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.
INFORMATION
Mixing station. If your system layout contains 2 LWT
zones, you need to install a mixing station in front of the
main LWT zone.
# Code
[4.4] [7‑02] ▪ 0: Single zone
Only one leaving water temperature
zone:
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 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.

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.
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
(1)
[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~
(1) If the value [4-07] is set lower, then the lowest value will be
used in all operation modes.
6.2.5

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
