Installation and Operating Instructions
Design Convector Heater MFP100-200W
4.1 Temperature Setback Using a Pilot Wire
To set back the temperature adjusted on the thermostat (by
5° C) the black pilot wire circuit is controlled by an external
electrical contact with any phase , e.g. a timer. Any ancillary
appliances connected via the pilot wire are controlled in the
same way. .

4.2 Automatic Turning On and Off
If a programming cassette (accessory) is used for automatic
switching on and off, any additional appliances which are
connected to the black pilot wire will be controlled in the same
manner..

5. Heating Operation
The heater controls are
located behind a hinged
cover on the right side of
the heater top. .
The heater is switched on and off by means of the power
switch. The right indicator light (B) is illuminated when the
appliance is switched on. .
5.1 Thermostat
The heater is fitted with an electronic thermostat by means of
which the room temperature can be controlled by choosing a
suitable setting. The setting corresponds to a room
temperature of approx. 6 °C (frost protection setting). To
increase the temperature, move the slide switch to the right.
The left indicator light (A) is illuminated when the heater is in
the heating mode.
Note - If you do not switch on your heater may have a cause,
that the slider of the thermostat is set at a lower temperature
than the current room temperature
Attention!
Depending on room size, heat demand and thermostat setting,
rooms can be heated over a silent heating. This may cause a
danger to persons who are not able to leave the room in case
of excessive temperature.
5.2 Limiting theThermostat Setting Range
The setting range of the thermostat can be defined by means
of the two limiting pins (A) provided on the heater rear panel.
One pin each is provided for limiting the upper and lower
value.
The pins can be removed by moving them back and forth, e.g.
by means of flat nose pliers, and be inserted into the holes in
the thermostat.
6. Overheat Protection
7. The heater is equipped with an overheat protection for your
safety. If the air circulation is impeded, the heater is switched
off by the overheat protection. Once the heater has cooled
sufficiently, it will automatically switch on again
In the event that the overheat protection trips repeatedly, the
cause of overheating must be determined, e.g. air grille is
covered or obstructed.
For maximum heat output it is essential that you keep the air
inlet and outlet openings free of dust. Clean the heater with a
vacuum cleaner before the start of the heating season!
8. Malfunctions
If there is no heat output from the unit, please check that the
heater is switched on and that the thermostat is set to the
desired temperature. Subsequently check the circuit breaker
on the main service panel, or the fuse, to ensure that they have
not tripped or blown.
