4.7 Safety devices
Heat dissipation
– This function of the boiler control is a safety
device that prevents overheating of the boiler.
– Functioning: If the boiler temperature exceeds the
set
Heat dissipation maximum boiler temperature ,
all pumps relating to the energy consumer units
(e.g. heating circuit, DHW tank, buffer tank, etc.)
will be switched on and the heating circuit mixer
opened. In this way, energy is drained from the
boiler and it may be possible to prevent other
safety devices tripping.
–
If the boiler temperature falls below the set Heat
dissipation maximum boiler temperature minus
1°C again, the pumps and mixers will be operated
in standard mode again.
[1] The parameter can be found in the
Service menu | System
parameters button | General settings button.
Overtemperature reset (OTR)
– The safety temperature limiter (STL) is a safety
device that prevents overheating of the boiler.
– Functioning: The STL stops the heating process
at a boiler temperature ~95°C (exclusively elec-
trical function; fuel and air supply are interrupted).
–
After tripping, the STL must be manually released
again by unscrewing the black sealing cap
1 and
pressing the button as soon as the boiler tem-
perature falls below 60°C.
–
If the safety overtemperature reset trips, this is
indicated in the boiler control display.

Safety valve (to protect against excess pres-
sure in the system)
–
The safety valve 1 is a safety device for protecting
against overpressure in the water circuit of the
heating system.
– Functioning: The valve opens when the system
pressure exceeds 3 bar. Water/steam are dischar-
ged into an open drain via a discharge line, which
avoids consequential damage to the heating sys-
tem. The valve is closed during normal operation.
– For normative specification see EN 12828.

i
The safety valve (or a boiler safety group) is
not included in the boiler. On-site installation
required.
EMERGENCY OFF switch
–
The EMERGENCY OFF switch is a manually ope-
rated safety device. The burner and the fuel sup-
ply to the boiler are stopped. Circulation pumps
remain in operation to dissipate heat and cool the
boiler.
–
The switch must be installed outside the boiler
room in a safe place that is easy to access.
