Preparation
3.1
Preparing installation site
NOTICE
This unit is designed for operation on 2 temperature zones:
▪ underfloor heating in the
main zone
(water
temperature 35°C), this is the zone with the
lowest
water temperature
,
▪ radiators in the
additional zone
(water temperature
45°C), this is the zone with the
highest water
temperature
.
3.1.1
Installation site requirements of the
indoor unit
▪ Mind the following spacing installation guidelines:
>500
>10
>10
(mm)
▪ The indoor unit is designed for indoor installation only and for
ambient temperatures ranging from 5~35°C.
NOTICE
When the temperature in multiple rooms is controlled by 1
thermostat, do NOT place a thermostatic valve on the
emitter in the room where the thermostat is installed.
3.2
Preparing water piping
NOTICE
In case of plastic pipes, make sure they are fully oxygen
diffusion tight according to DIN 4726. The diffusion of
oxygen into the piping can lead to excessive corrosion.
3.2.1
To check the water volume and flow rate
Minimum water volume
Check that the total water volume in the installation is minimum
10 litre for 08 and 20 litre for EHVZ16, the internal water
volume of the indoor unit NOT included. Do
NOT
split up the
minimum water volume over the 2 temperature zones.
It is sufficient to foresee the minimum water volume on the main
zone. In case of underfloor heating, this is easily done by 1 floor
heating loop that never will be closed by a (remotely) controlled
valve.
It is NOT required to foresee the minimum water volume on the
additional zone.
