1. General information

1.1. Information regarding installation and ope-
rating instructions
Keep installation and operating instructions
safe. They must be handed over to the new
owner, if ownership changes. The instructions
must always be available for the specialist tra-
desman as servicing and repair reference.
The installation and operating instructions serve
the installer to install the pump group professio-
nally, to put it into operation and to service it.
Read installation and operating instructions in their
entirety before work commences.

1.2. Symbol explanation

Safety guidelines are displayed by symbols. These
guidelines are to be observed to prevent accidents,
damage to property and malfunctions.
DANGER
Imminent danger to life and limb
Attention
Potential dangerous situation for
product, system or hygiene

MAINTENANCE ADVICE

The advice must be followed for a
successful maintenance of the
pump group.

2. Safety notes

The pump group must be installed by a specialist
company with due consideration of valid standards
and rules.
Oventrop GmbH & Co. KG does not accept liability
for damages and malfunctions caused by nonob-
servance of these instructions.
The circulation station is equipped with thermo-
meters for potable water temperature control.
The potable water temperatures must be
monitored Excess temperatures may
lead to leakages in the pipework caused
by mechanical tensions or to a break-
down especially where plastic pipes are
used.

The electrical connection must be car-
ried out by a qualified tradesman
The regulations of the local energy
supplier must be observed
The NIN (CENELEC) regulations are to
be observed
3. Application
The circulation station is installed between the hot
water storage cylinder and the circulation system.
The required circulation temperature is set at the
thermostatic mixing valve. Back-flow of the circu-
lation water during hot water consumption is
prevented by the integrated non-return check val-
ves.
In order to avoid damage to the pipe-
work, pumps and valves caused by calcificati-
on, the fitting of water treatment equipment is
recommended if the water is very calciferous.
Especially in hot water systems, this may lead
to malfunctions or breakdown of the valves.
The national guidelines must be observed.
4. Function
The circulation station "Regucirc M" serves the
operation and temperature control of a potable
water circulation system. Temperature control is
carried out by a high quality thermostatic mixing
valve made of bronze. The station is equipped with
an energy-saving high-efficiency pump Biral AX
20-4 BLUE which can be operated on different
characteristic lines according to the customers'
requirements. According to the demands, the high-
efficiency pump is automatically adjusted to the
optimum output together with a small return-flow
channel. If a high quantity of hot water is with-
drawn, then the circulation volume flow is fed via
the storage cylinder and the pump is adjusted to
full throttle. A hot water supply to all parts of the
system is thus guaranteed. If no hot water is drawn
off the circulation system, the plant is warmed up
to the temperature, set at the thermostatic mixing
valve. Then the thermostatic mixing valve closes
the hot water and opens the cold water supply.
The circulation volume flow delivered by the high-
efficiency pump can now pass via the bypass ca-
pillaries. The power consumption of the high-effi-
ciency pump is reduced due to the high hydronic
pipe resistance of the capillaries.
If the cold water supply is interrupted, the hot water
supply is automatically shut off by the thermostatic
mixing valve with integrated fail-safe function and
any risk of scalding is avoided.
