5 Construction and function

5.1 Summary and functional description
The "Regumat" with heat meter connection set is
available as standard model or with three-way mixing
valve.
The "Regumat S" allows the isolation of the heating
circuit. It consists of an isolation device with thermo-
meters integrated in the handles and two distance
pieces for length compensation in the supply and
return pipe. The check valve integrated in the return
pipe prevents gravity circulation.
The "Regumat M3" has the same design and function
as the "Regumat S". It is additionally equipped with a
three-way mixing valve and an actuator. The three-way
mixing valve serves to regulate the flow temperature
and has a bypass with manual presetting. A manually
set return flow share can be added to the supply pipe
via this bypass in order to reduce the flow temperature
of a surface heating for instance.
The boiler connection set is supplied without pump
and heat meter. The components are supplied loosely
connected. All connections have to be tightened after
installation of the pump and heat meter.
The connection box of the pump must be in 9 o'clock
position.
On delivery, the supply is on the right hand side, but
the supply and return can be changed on site (see
6.1). The mixing valve does not have to be changed.
The product groups are suitable for standard high-
efficiency pumps (length 180 mm) and heat meters
(installation length 110 or 130 mm) which are not
supplied with the "Regumat".
Energy consumption of the heating system can be
measured by installing a heat meter into the boiler
connection system.
The heat meter is installed in the return pipe (on
delivery on the left hand side). The temperature sensor
has to be installed on the supply side of the isolating
device. The insertion block has to be adapted to the
respective heat meter (see 5.6).
An adaptation to the pump which is installed in the
supply pipe (on delivery on the right hand side), is not
necessary.
NOTICE
When the circulation pump is switched off, a low
gravity circulation depending on the circulation
pressure is still possible within the heating system
despite the check valve as the latter is not tight
sealing.
