Setting the room thermostat
1. Select the desired temperature level via the infinitely
variable rotary switch of the room thermostat (6).
ð
The heating switches off automatically upon reaching
the set temperature. If the temperature falls below the
set temperature, the heating switches back on.
To find the ideal thermostat setting, please proceed as follows:
1. Set the rotary switch of the room thermostat (6) to the
highest level.
ð
As soon as the desired temperature has been reached,
slowly turn the rotary switch of the room thermostat
back until the power level flip switch (5 and 7) is no
longer illuminated.
ð
The device now automatically maintains the desired
temperature level.
Automatic temperature control via the room thermostat
•
Upon reaching the maximum operating temperature of the
heating medium in performance level 3 the device reduces
its performance to level 2.
•
When falling below the maximum operating temperature of
the heating medium in performance level 3, the heating
will automatically switch back over to level 3.
•
When the device is set to performance level 1 or
performance level 2, the operating temperature of the
heating medium will not be controlled automatically. Upon
reaching the preselected room temperature, the device
switches off completely.
Frost monitor function
The device is equipped with a frost monitor function that
prevents the room temperature from falling below the frost
protection temperature. Please proceed as follows to activate
the frost monitor function:
1. Set the power level flip switch (7) to position
I
.
ð
The power level flip switch (7) is illuminated.
2. Turn the infinitely variable rotary switch of the room
thermostat (6) to the
-
position.
ð
In this position, the room thermostat switches on the
heating automatically if the room temperature drops
below the frost protection temperature.

Errors and faults
Warning of electrical voltage
Tasks which require the device to be opened must
only be carried out by authorised specialist
companies or by Trotec.
The device has been checked for proper functioning several
times during production. If malfunctions occur nonetheless,
check the device according to the following list.
The device makes noises after switch-on:
•
The heating medium oil expands due to heating. This is
what causes the noise. It is a perfectly normal process. No
measures are required.
The device does not start:
•
Check the power connection.
•
Check the power cable and mains plug for damages.
•
Check the on-site fusing.
•
Check the room temperature. The room thermostat may
have switched off, because the desired room temperature
has been reached.
•
Check whether the device is standing upright and on level
ground. The tilt protection may have been tripped owing to
the fact that the device was knocked over. Always put up
the device in an upright position on a suitable, sufficiently
dimensioned surface.
•
The room thermostat might be defective. Have a defective
room thermostat replaced by a specialist electrical
company.
•
Check whether the overheating protection has tripped (see
chapter Safety).
•
Wait for 10 minutes before restarting the device. If the
device is not starting, have the electrics checked by a
specialist company or by Trotec.
