5 Construction and function
5.1 Survey and functional description
"Regumat F-130"
The fixed value control set allows the flow temperature
control and limitation in combined radiator/surface
heating systems. Flow temperature is controlled with
the help of a three-way mixing valve in combination
with a temperature controller with immersion sensor.
Control range: 20-50°C
"Regumat F-180"
Function identical to "Regumat F-130" but pump
length 180 mm and with pump ball valve at the pump
inlet.
The pump ball valve serves the isolation when repla-
cing the pump.
"Regumat FR-180"
Function identical to "Regumat F-130" but with pump
length 180 mm and bronze pump body to avoid the
risk of corrosion in case of system related penetration
of oxygen. For open vented systems.

5.3 Installation advice
WARNING
Before starting work, please make sure that the
pipework all components have cooled down to
ambient temperature and have been drained.
Before starting work, please ensure that all
electric components (controllers, pumps etc.)
are disconnected from power supply
The station is supplied pre-assembled.
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 with
a torque of 45Nm.
Check connections for leaks.
The connection box of the pump must be in 9 o'clock
position.

5.4 Check valve
The check valve prevents a gravity circulation of the
heating water when the pump is switched off.

Illustr. 5.1 Check valve
The check valve is closed in operating position; pas-
sage is only possible in flow direction.
When putting the system into operation and during
maintenance work (filling and flushing), the check valve
must be opened.
If the check valve is opened, flow is possible in both
directions.
During heating operation, the check valve must be set
to operating position.
6 Installation and assembly
6.1 Installation
The pipework has to be flushed thoroughly before in-
stalling the fixed value control set. It can be installed
in any position (horizontal, inclined or vertical, in as-
cending or descending sections) provided that the di-
rection of flow conforms to the arrow on the fixed
value control set.
Warning advice under paragraph 2 (safety notes)
must be observed
PRECAUTION
– Do not use any lubricant or oil when installing
the valve as these may destroy the seals. If
necessary, all dirt particles and lubricant or
oil residues must be removed from the pipe-
work by flushing the latter.
– When choosing the operating fluid, the latest
technical development has to be considered
(e.g. VDI 2035).
– Please protect against external forces (e.g.
impacts, vibrations etc.).
After installation, check all installation points for leaks.
