Behavior in the event of an emergency

1. Switch the device off.
2. In an emergency, disconnect the device from the mains feed-in: Hold onto the mains plug while pulling the power cable out of the mains socket.
3. Do not reconnect a defective device to the mains.

Overheating protection
The device is provided with a safety thermostat which is activated by overheating the device (when exceeding the operating temperature).
Investigate the cause of overheating.
If the safety thermostat does not switch in the event of overheating, the overheating protection will be tripped. In that case, the device switches off completely. If so, please contact customer service to have the overheating protection replaced.

Tilt protection
The device comes equipped with tilt protection. The tilt protection is a safety device intended to minimize the risk of fire in case the device is tipped over inadvertently. The device will be switched off when knocked over (or if its upright position is changed in any other manner).
The tilt protection switches the device off when it is inclined out of its vertical position. The device can again be used as usual only a few seconds after placing it back in a vertical position and on solid ground.

Information about the device
Device description
The oil-filled radiator is used to generate warm air for interior spaces.
The device comes with 3 performance levels and an infinitely variable thermostat with the following maximum power values.

• TRH 20 E: 2,000 watts
• TRH 21 E: 2,500 watts
• TRH 22 E: 2,400 watts (performance with fan)
• TRH 23 E: 2,900 watts (performance with fan)
• TRH 24 E: 2,200 watts

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 long-term heat storage capacity. On these grounds, the heating medium oil can guarantee a continuous heat emission. The radiator’s 9 or 11 ribs increase the heat radiating surface and so enhance its effectiveness.
The devices are further equipped with overheating protection and tilt protection.
The device TRH 22 E / TRH 23 E comes with an additional turbo function. Accordingly, a turbo blower with an additional PTC heating element ensures quick and effective initial room heating.

   ⇒ When the room thermostat is switched on the operating control lamp (10) will be illuminated.
   ⇒ After approx. 8 to 10 min the device will have reached the set power.

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

1. Set the rotary switch of the room thermostat (8) to the highest level.
2. As soon as the desired temperature has been reached, slowly turn the rotary switch of the room thermostat back until the operating control lamp (10) goes out.
   ⇒ The device now automatically maintains the desired temperature level.

Automatic temperature control via the room thermostat (TRH 20 E / TRH 21 E / TRH 22 E and TRH 23 E):

• Upon reaching the operating temperature of the heating medium in performance levels 2 and 3 the device reduces its power to level 1.
• When falling below the operating temperature of the heating medium, the heating will automatically switch back over to level 2 or level 3.
• When the device is set to performance level 1, the operating temperature of the heating medium will not be controlled automatically. Upon reaching the preselected room temperature, the device switches off completely.

Automatic temperature control via the room thermostat (TRH 24 E):

• Select the desired temperature via the infinitely variable rotary switch of the room thermostat (8). The heating switches off automatically upon reaching the set temperature. If the temperature falls below the set temperature. the heating switches back on.
• Upon reaching the operating temperature of the heating medium in level 3 the device reduces its power to level 2.
• When falling below the operating temperature of the heating medium, 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
