Device description

The oil-filled radiators TRH 20 E / TRH 22 E serve to generate
warm air in interior spaces.

The device comes with 3heating levels of up to 2,000W and an
infinitely variable thermostat.

The heat electrically generated by the heating elements within
the device is absorbed by the heating medium oil. The heating
medium oil offers the advantages of quick heat-up and long­term heat storage capacity. On these grounds the heating
medium oil can guarantee a continuous heat emission. The
radiator's 9ribs increase the heat radiating surface and so
enhance its effectiveness.

The device is further equipped with an overheating protection
and a tilt protection.

The device TRH 22 E is further provided with a turbo function.
Accordingly a turbo blower with additional PTC heating element
ensures the quick and effective initial room heating.

Switching the device on

Once you have completely installed the device as described in
the Start-up chapter, you can switch it on.

Info

The device will not be switched on until the room
temperature falls below the temperature set at the
room thermostat.

Setting the heating level

1. Set the rotary switch for heating level selection(9) to the
desired heating level.

Setting the room thermostat

1. Select the desired temperature via the stepless rotary
switch(8) of the room thermostat.

ð When the room thermostat is switched on the operating

control lamp(10) will be illuminated.

ð After approx. 10min the device will have reached the

set heat output.

To find the ideal thermostat setting, please proceed as follows:

• Set the thermostat control to maximum.

• As soon as the desired temperature has been reached,
slowly turn the thermostat control back until the operating
control lamp(10) goes out.

• The device now automatically maintains the desired
temperature level.

The room thermostat controls the room temperature
automatically:

• Upon reaching the set value in heating level2 and 3 the
device reduces its heating performance to 800W (level1).

• When falling below the set value, the heating will
automatically switch back over to 1,200W (level2)
or2,000W (level3).

When the device is set to heating level1, the room temperature
will not be controlled automatically.

Frost monitor function:

1. Set the heating level to level1.

2. Turn the rotary switch for the room thermostat(8) to a
position just above -. In this position, the room thermostat
switches on the heating automatically if the room
temperature drops below the frost protection temperature.

oil-filled radiator TRH 20 E / TRH 22 E

Switching on the turbo blower (TRH22E only)

1. Set the flip switch for the blower(7) to I.

ð The lamp at the flip switch will be illuminated.
ð The blower will start to run when the device produces

heat.

ð The blower will turn off when the room thermostat

switches off the heating.

Shutdown

Warning of electrical voltage

Do not touch the mains plug with wet or damp hands.

• Set both rotary switches(8, 9) to position 0 or -.

• Hold onto the mains plug while pulling the power cable out
of the mains socket.

• Allow the device to cool down completely.

• Clean the device according to the Maintenance chapter.

• Store the device according to the Storage chapter.

Errors and faults

Warning of electrical voltage

Tasks which require the housing 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.

The device is switched on, but the heating is not operating:

• Check the room temperature. The room thermostat may
have switched off, because the desired room temperature
has been reached.

• Check whether the overheating protection has tripped, see
chapter Safety.

• The heating resistor might have blown. Have a defective
heating resistor replaced by a specialist electrical
company.

• The room thermostat might be defective. Have a defective
room thermostat replaced by a specialist electrical
company.

The blower is not running (TRH 22 E only):

• Check whether the device is switched on.

• Check the power connection.

• Check the power cable and mains plug for damages.

• Check the room temperature. When the room thermostat
switches off, the blower turns off as well.

• The fan motor might be defective. Have a defective fan
motor replaced by a specialist electrical company.

The air current is reduced (TRH 22 E only):

• Check the air inlet and outlet. Make sure that air inlet and
outlet are not obstructed. Remove any dirt. Observe the
minimum distance from walls or other objects according to
the technical data.

Note

Wait for at least 3 minutes after maintenance and
repair work. Only then switch the device back on.

Your device still does not operate correctly after these
checks?
