3.2 Functional description
The return temperature from the fresh water station
to the storage cylinder can vary considerably de-
pending on the operating status. When drawing off
hot potable water, very low return temperatures may
be reached. Whereas considerably higher return tem-
peratures can be expected during circulation opera-
tion without hot potable water consumption.
The temperature of the water in the upper section
of the storage cylinder section is higher than in the
lower section. This temperature layering is necessary
forefcientoperationofthestoragecylinder.
The aim of return temperature layering is to disturb
the temperature layering in the storage cylinder as lit-
tle as possible. The returning water should ideally be
layered in the section of the storage cylinder where
the stored water has the same temperature.
The valve for return temperature layering with ac-
tuator DN 25 ensures the temperature-controlled
layering of the returning water in the lower or central
storage cylinder section. Temperature sensors in the
storage cylinder and in the fresh water station pro-
vide the controller of the fresh water station with the
necessary data for calculating the appropriate valve
position.
The controller of the fresh water station takes over
the control of the actuator according to the required
layering position.

your fresh water station!!
5.1 Installation of the valve for return
layering
NOTICE
Malfunctions and damage to the actuator
due to a wrong installation position
The actuator can be damaged and its function
be impaired if it is installed in a vertical down-
ward position.
fDo not install the valve for return layering
with actuator DN 25 in a vertical downward
position.
Illust. 5: Installation position
WARNING
Risk of injury from pressurised uids
Fluids escaping under pressure may lead to
injuries.
fOnly carry out installation work when the
system is depressurised.
fWhenretrottinganexistinginstallation:
Drain the system or close the supply
pipes of the section of the system and
depressurise it.
fWear safety gloves.
CAUTION
Risk of scalding due to hot uids
If the installation has been in operation, there
is a risk of scalding due to the unintentional
discharge of hot water or water steam.
fAllow the system to cool down.
fWear safety goggles.
CAUTION
Risk of burns due to hot components
Any unprotected contact with hot compo-
nents may lead to burns.
fWear safety gloves.
Ensure that the product remains easily acces-
sible.
NOTICE
Risk of damage to property due to foreign
bodies (e.g. shavings, dirt), sealants and
lubricants
Valves can be damaged and their function be
impaired by foreign bodies, greasing agents
or oil.
fDo not use any greasing agents or oil
during installation.
fFlush any dirt particles or grease or oil
residues out of the pipework before in-
stalling the product.
fConsider the latest technical status (e.g.
VDI 2035) when choosing the operating
uid.
NOTICE
Risk of damage due to pressure surges
Suddenllingofthestationwithwatermay
lead to damage, for instance to the sensors
or sealing points.
fAlways open and close the ball valves
slowly.
1. Completely disconnect your fresh water station
from the power supply.
2. Slowly close the isolating ball valve for storage
cylinder circuit return.
3. Slowly close the isolating ball valve for storage
cylinder circuit supply.
4. Drain the water from the storage cylinder circuit at
the lower connection of the storage cylinder.
