Information on the safety devices
The safety devices are equipped with a sensor monitor-
ing feature and are resistant to cold down to -20°C . Be-
low -20°C, it switches off; when the temperature ri ses
above this temperature, it switches on again.
When the sensor or capillary tube is damaged or when
an excess temperature of approximately 220°C is
reached, the filling medium is emptied and the safety de-
vice switches off. The controller is no longer operable
and must be replaced.
If it is necessary to replace the STB, only the original
REMKO spare part should be used.
◊
Make sure to install and mount the device carefully.
◊
Do not bend the capillary tubes in the direct vicinity
of solder points.
◊
When installing the capillary tubes, be careful not to
damage or bend them too sharply.
◊
The sensors may only be mounted in the mounting
strap.
◊
The sensors must always be free of dust and dirt.
Installation Regulations
When the equipment is in use, the safety guidelines of
the employers' liability insurance associations, the re-
spective country construction ordinances, and the burn-
ing appliance regulations basically apply.
◊
Avoid underpressure or overpressure in mounting
rooms since these states always lead to combus-
tion-technical problems.
◊
Make sure the fresh air supply has been adapted to
the respective fan output (see model plate).
The forced-air oil burner must be equipped with a
separate combustion air supply if necessary.
Installation in closed, well-ventilated rooms without
a chimney connection
◊
The equipment may only be operated when the mini-
mum amount of air required for combustion accord-
ing to § 38 Sect. 4 (page 5) is supplied.
◊
A safe exhaust of the waste gases is to be ensured
to exclude an inadmissible pollution of the room air.
Fresh air is supplied from below.
Waste gases are expelled upwards.
Outdoor installation
◊
Due to the operation of the equipment, no dangers
or unreasonable nuisances may arise.
◊
The equipment operator must guarantee that unau-
thorised persons cannot manipulate the equipment
or the energy supply.
◊
Because rain and snow can be pulled in through the
supply air fan, a suitable protective covering should be
used.
Heating rooms
◊
The equipment may be used for room heating only
with a room thermostat (accessory).
◊
The supply of the fresh air required for proper com-
bustion must be guaranteed.
Safety distances
◊
To guarantee safe equipment operation and mainte-
nance, a safety distance of 1.5 metres around the
device must be observed.
◊
The floor and ceiling must be fire-resistant.
Electrical connection
◊
The equipment is operated at 1~ 230 V/50 Hz.
◊
The electrical connection of the equipment must be
performed at a certain supply point with an earth-
leakage circuit breaker according to VDE 0100 § 55.
◊
Suitable cable extensions may be used only when
unrolled.
Safety Devices
The equipment has the following safety or monitoring
devices:
◊
Temperature control thermostat (TR)
◊
Temperature monitor (TW)
◊
Safety temperature limiter (STB)
Temperature control thermostat (TR)
The temperature control thermostat switches the circu-
lating fan on and off. The switching point is set in the
switch box using the "Scale 21 – 60" controller.
Setpoint approx. 35 – 40°C.
Temperature monitor (TW)
In heating mode, the temperature monitor limits both
the temperature of the unit and of the air being blown
out. The switching point is set in the switch box using
the "Scale 34 – 110" controller.
Setpoint approx. 80 – 85 °C.
Safety temperature limiter (STB)
The STB controls the temperature monitor. The switching
point has a permanent setting.
The burner is prevented from being restarted if the STB
is activated.
After the cover next to the control panel is removed, the
reset button must be pressed from the outside.
After the STB has been reset, the cover must be re-
mounted.
Before an STB reset, check the operating conditions
to ensure that the STB temperature is not exceeded
again.
