5 Construction and function

5.1 Summary and functional description
The product group is available with and without circu-
lation pump.
The individual components of the model without pump
are supplied loosely connected. After installation of
the pump, the connections have to be tightened.
The connection box of the pump must be in 9 o'clock
position.
On delivery, the supply pipe is on the right hand side.
But the supply and the return can be changed on site
(see 6.1). The mixing valve does not have to be
changed.
The "Regumat S" allows the isolation of the heating
circuit. It consists of an isolation device with thermo-
meters in the handles and a distance piece for length
compensation in the supply pipe. The check valve in-
tegrated in the return pipe avoids 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 tempera-
ture and has a bypass with manual presetting. A ma-
nually set return flow share can be added to the supply
pipe via this bypass in order to reduce the flow tem-
perature of a surface heating e.g.
The "Regumat M4" has the same design and function
as the "Regumat S". It is additionally equipped with a
bronze four-way mixing valve and an actuator. The
four-way mixing valve serves to regulate the flow
temperature. The return temperature of the boiler is
increased at the same time. The bypass with manual
presetting integrated in the mixing valve serves to
regulate the flow temperature in systems with a high
boiler temperature and a low flow temperature (e.g.
surface heating systems). This bypass constantly adds
return water to the supply pipe.
5.2 Check valve
The product group is supplied pre-assembled. During
heating operation, the slot for opening the check valve
must be in horizontal position.

Operating position: Check valve closed, passage only
in flow direction.

When putting the system into operation and during

maintenance work (filling and flushing), the check valve
must be opened.
Isolation function inactive: Check valve opened, flow
is possible in both directions.
During heating operation, the check valve must be set
to operating position.
