CAUTION
Prior to resetting the safety
temperature cut-out before
resuming operation, it is vital
to identify the possible causes
for it having been triggered.
The thermostat (TR) controls
operation of the fan.
The temperature monitor (TW)
limits the heating output during
operation via the forced air oil
burner.
The safety temperature cut-out
(STB) interrupts the heating
function in the case of extreme
overheating or failure or defect of
the TW.
The red warning lamp
„Overheating“ on the switch cabi-
net lights up.
Resetting the STB is performed
using the „Overheating“ reset
button on the switch cabinet and
is only possible after the device has
cooled down.
The fan motor is controlled by a
thermal overload relay. In the case
of overload of the motor,
operation is interrupted by the
relay and the red warning lamp
“Fan” lights up on the
switch
cabinet .
Resetting is performed using the
"fan" reset button on the
switch
cabinet .
All electrical components are
additionally protected by circuit
breakers.
Resetting can only be performed
after opening the
switch cabinet .
Prior to opening the switch
cabinet, it is vital that the device
is disconnected from the mains
power supply.
Dependent upon the heating
requirement, the operation
described is repeated auto-
matically.
After the device is switched off by
the operating switch or a room
thermostat, the inlet air fan
continues to run for a while to cool
the combustion chamber and heat
exchanger and then turns off auto-
matically. This process may repeat
itself several times.
Monitoring operation
of the device
All functions of the device are
monitored safely and fully auto-
matically by the thermostat of the
three fold combination
controller and the automatic
burner unit (component of the
forced air oil burner).
In the event of irregularities or
extinguishing of the flame, the
device is switched off by the auto-
matic burner unit.
The warning light of the automatic
unit and the red warning lamp
“Burner” light up on the switch
cabinet.
Restarting can only be performed
by means of manually resetting
the automatic burner unit using
the reset button “Burner” on the
switch cabinet.
Suitable locations for
operating the device
As a directly fuelled warm air gen-
erator, the device provides
immediate heat.
It is exclusively used for commer-
cial heating and ventilating
purposes.
The devices are used to heat or
control the temperature of sites
such as e.g.
�
Warehouses
�
Exhibition rooms
�
Fair halls
�
Lightweight construction
buildings
�
Marquees
�
Large building sites
Sequence of functions
When the device is switched on,
the forced air oil burner starts
automatically. This is confirmed by
the green operation lamp
“Heating” on the switch cabinet
lighting up.
When in operation using a room
thermostat, the forced air oil
burner only starts up when heat is
required.
The combustion chamber with
heat exchanger is heated up to the
target temperature of the
temperature monitor (80 to 85
°C).
The thermostat (target
temperature 35 to 40 °C) auto-
matically switches on the inlet air
fan prior to this.
This is confirmed by the green
operation lamp “Fan” on the
switch cabinet lighting up.
Hot air is blown out.
