Safety equipment
The units have the following
control or safety equipment:
Temperature controller (TR)
The temperature controller
controls the switching on and off
of the recirculating fan. The switch
point is set via the "Scale 21 -
60°" controller in the switching
cabinet.
Target value ca. 35 - 40 °C.
Temperature monitor (TW)
The temperature monitor limits
the unit or outlet temperature
in heating mode via the burner.
The switch point is set via
the "Scale 34 - 110°" controller
in the switching cabinet.
Target value ca. 80 - 85 °C.
Safety temperature limiter (STB)
The unit is permanently
switched off by the safety
temperature limiter (STB) in
the event of the unit overheating
or a temperature monitor
malfunction.
Manual resetting is required.
Automatic burner
The unit is permanently
switched off by the automatic
burner through the optical
flame monitoring in the event
of irregularities in the combustion,
the flame extinguishing, fuel
deficiencies etc.
Manual resetting is required.
Regulating device
The temperature sensor
of the controller is self-monitoring.
The probes are cold-resistant
to -25 °C.
At temperatures below -25 °C
the controller current flow will be
interrupted - if the temperature
rises above -25 °C the current flow
will be released again.
In the event of the probe or
the capillary tube being damaged,
as well as if an overtemperature
of ca. 220 °C is reached, the fill
medium will be emptied and
the safety device is permanently
triggered.
Resetting is no longer possible.
The controller is no longer fully
functional and must be replaced.
Safety temperature limiter (STB)
The heating function is
permanently interrupted by
the safety temperature limiter
(STB) in the event of the units
overheating or malfunctioning.
Manually resetting of the STB
can only be implemented after
the units have cooled down.
The resetting of the STB is
implemented by actuating
the reset button 2.

ATTEnTiOn
If the safety temperature
limiter has been tripped then
the cause of the malfunction
should be identified and
rectified before resetting it.
nOTE
In order to prevent a renewed
exceedance of the triggering
temperature the operating
conditions of the unit should
be checked before resetting
the STB.
nOTE
Only
"REMKO original
replacement parts"
must be
used when replacing safety
devices.
ATTEnTiOn
Safety devices may be neither
bypassed nor disabled.
1. Unscrew protective cap [1].
2. Carefully press in the reset
button [2] with a suitable tool.
3. Screw the protective cap [1]
back on again.
■
Ensure that the device is fitted
properly
■
The capillary tubes must
not be kinked or bent in
the immediate vicinity
of the soldering points
■
The capillary tubes must not
be damaged or kinked during
installation
■
The probes must only be fitted
at the fastening points provided
by the factory
■
The probes must always be
free of dust and dirt in order
to be sure of their correct
functioning
