Wall mounting - See pictures on page 2-3
Mark out the distance between the brackets as shown in the table and in the draw-
ing below. Mark positions for the screw holes and secure the brackets to the wall
using suitable fastenings. Make sure that the brackets are even in depth, in case the
wall is not. Pull the spring retainer up to its upper position, hook the radiator onto
the lower part of the brackets and then press the top of the radiator towards the
brackets, whereupon the spring will be heard to click into position automatically.
A1
The distance between the radiator and the wall is 50 mm for all models.
* These models have an additional bracket in the centre.
** The bracket on this model is asymmetrically positioned, in order
to provide space for the thermostat.
*** The wall outlet box does not fit between the wall brackets for
this model. It is to be placed on the wall above the thermostat
instead. Instead of 120mm from the floor (as in the drawing) it
has to be placed at 335mm from the floor in this case.
A2
The vertical radiators are supplied with safety chains, which are fitted between the
radiator brackets and the wall brackets. Radiators with a height of 1,500 mm, or
higher, are provided with brackets in the middle.The radiators are mounted and fit-
ted by lifting up all the brackets to the mounting position (this is simplified by using
the enclosed hook) and then pressing the radiator to the brackets, whereby the
spring locks click into place. Check that all the brackets have hooked on.
B
For vertical SET-radiators, towel bars (HDH) are available as a compliment. One
HDH 300 respectively HDH 400 (corresponding to the radiator´s width) consists
of two bars with a fixed distance of 27cm.

Slave connection
The SET radiator can control another radiator in what is known as a master/slave
radiator installation.The total output that the master radiator can regulate is 2300
W. Slave radiators are connected as per the wiring diagram on the terminal box lid.
The master radiator's thermostat regulates the heat generated by the connected
radiators.
Model with plug and cord
If the model designation ends with a P, the radiator is delivered with a plug and is
to be connected to an existing socket. The plug fits both earthed and unearthed
sockets. It is not possible to use centrally controlled temperature reduction and slave
connections in this version.
All SET electric radiators are double-insulated, which means that
no earth connection is required.
Insulation class II IP klass 32
For use in dry areas as well as bathrooms, wet rooms.
Cleaning Cleaning Cleaning
Use ordinary liquid cleaners to clean the radiators. Do not use abrasive cleaners, as Use ordinary liquid cleaners to clean the radiators. Do not use abrasive cleaners, as
this will dull the surface finish. Marks such as oil etc. can easily be removed by using
a solvent such as acetone etc.
Remove any scratches in the surface layer by carefully polishing the surface with fine
abrasive paper.
Some notes on the material.
SET consists of finely ground granite cast into a binder.

Temperature control
The thermostat knob (2) provides a control range of 5-30°C. The elec-
tronic thermostat senses the room temperature at intervals of about 50
seconds. The green LED (1) above the thermostat knob lights when the
radiator is working.
Temperature setback
Switches S2, S3 and S4 control the thermostat's timer functions. Before
programming, they are to be set into right hand position. There are differ-
ent options:
1.Temperature setback of 4°C for 5 hours after S3 has been set at
(e. g. Monday morning). The setback is automatically repeated in 5 days at
the same time every day (here Monday to Friday). After 2 days without any
setback, the cycle starts again.
2.Temperature setback of 4°C for 7 hours after S4 has been set at 2.Temperature setback of 4°C for 7 hours after S4 has been set at
The setback is continually repeated at the same time every day, 7 days a
week (e. g. night setback).
3. Setback programs 5 and 7 hours can be combined overlapping up to 12
hours in 5 days. Example:The 5h-setback (S3) is set on Monday morning at hours in 5 days. Example:The 5h-setback (S3) is set on Monday morning at
8.00. At 10.00, S4 is set at 8.00. At 10.00, S4 is set at
the temperature by 4°C between 8.00 and 17.00 in 5 days. On Saturday
and Sunday, the temperature is being reduced between 10.00 and 17.00, if and Sunday, the temperature is being reduced between 10.00 and 17.00, if and Sunday, the temperature is being reduced between 10.00 and 17.00, if and Sunday, the temperature is being reduced between 10.00 and 17.00, if and Sunday, the temperature is being reduced between 10.00 and 17.00, if

is switched back into right hand position, the program is reactivated. To
rense all programs, switch off the radiator with S1 for at least 30 min. To
change the starting time for one program, set the program switch (S3 or change the starting time for one program, set the program switch (S3 or
S4) onto S4) onto at the new chosen time. Prior timer programs on this switch at the new chosen time. Prior timer programs on this switch
are thus taken away.
The thermostat keeps timer programs under a power cut of less than 30
min. After a longer power cut, the radiator starts with a new setback after
the power cut and has to be reprogramed. Lost timer program is shown
by the LED (3) under the thermostat knob flashing quickly.

Frost protection

With the thermostat knob in lowest temperature position, you achieve
frost protection (about +7°C). Regardless of the timer settings, the radiator
will not allow the room temperature to drop below this value.
Maximum surface temperature
If the maximum surface temperature shall be reduced to 60°C, remove the
shorting link (4) on the PCB (5) inside the thermostat box (see picture C).
With the link removed, it has to be taken into account that the radiator
delivers only about half of its original output.This limitation overrides room
temperature control: if the surface temperature rises above the respective
maximum permissible temperature, room temperature control is locked
out until the surface temperature has dropped to 5°C below the set value.
Control then reverts to normal room temperature mode.
Overheating protection
The SET radiator is also provided with an overheating protection which
operates if the radiator should be accidentally covered etc. The power
supply is interrupted and the radiator cools down. To reset the overheat-
ing cutout, turn the main On/Off switch off for about 5 minutes. Turn the
switch on again, and the radiator will work normally.
D Adjustement of the grade scale
In case the grade scale does not accord to the room temperature, take
off the thermostat knob (2). Adjust the scale by taking off and turning the
inner part of the knob into correct position. Reassemble and put back the
knob.
Pilot wire: external control of temperature setback
Pilot wire: 230V AC phase. The temperature is reduced by ca. 4°C of the
chosen temperature. If the temperature already has been reduced by the
normal timer control on the radiator, it will be reduced by a further 4°C,
although not below the frost protection limit.When the pilot wire mode is
in operation, the LED beneath the thermostat knob flashes slowly.
NB: the radiator must be installed by an
authorised electrician only.
The radiator must not be mounted below an electrical socket outlet.
If the radiator is installed in a bathroom or shower room,
it must be installed so that it is not possible to reach the switch or
thermostat from the bath or shower.
