6. The heang element is intended to work in a liquid agent environment. It is advised
not to turn the device on in dry condions for longer than 5 seconds.
Do not touch metal parts – burning risk. Always make sure that the wire does not
touch the heang element that is hot.
7. The device must not be connected while being installed. Unplug the device or discon-
nect the power wire from electrical circuit. Put the casing on the body of the heang
element unit before plugging the device. It is necessary to secure the control panel
with the right tool in order for the device to work as required [4].
8. Do not open the casing.
9. Heang element’s electric output cannot exceed 100% heang output of the radiator
for the following parameters: 75/65/20°C.
10. Pressure inside the radiator must not exceed the pressure value recommended
by the radiator’s manufacturer or the pressure of 10 atmospheres for the heang
element. Exceeding of recommended pressures may result in the radiator or heang
element damage and cause possible threat for health, life and property.
11. An air pillow of the correct parameters should always be allowed for inside an
electric radiator (see → Installaon).
12. In case of a dual fuel radiator (connected to the central heang system) one of the
valves should be le open prior to turning the heang element on and during its
operaon in order for the excess water created due to its heat expansiveness to be
pushed out. Leaving both valves closed will result in excessive pressure growth which
may lead to damaging of the heang element or radiator (see → Dual fuel radiator/
Installaon)
13. The device is intended for home use.
14. The device is not intended for use by children, persons with limited mental capacity
or those who do not have sucient knowledge or experience required for handling
this type of equipment. In such cases, control or training by persons responsible for
safety of the above menoned is required.

Heang element unit heats the radiator that it is installed in. The device has
a user-friendly temperature regulaon system allowing the device to work with only a
half or full of its heang output.
Buon is used to turn the device on / o.
When turned o and then back on again, the device will heat with the same heang
output as before it was turned o.
Buon is used to set the ECONOMICAL mode – this is indicated by a yellow diode
in the top le corner (the device will start operang by turning itself on and o every 7
seconds).
Buon is used to set the COMFORT mode (the device will operate with its full
output connuously) – this is indicated by a red diode in the boom right corner.
Built-in temperature sensor protects the device from overheang, liming the tempera-
ture of the radiator to maximum of 60°C.
Construcon of the heang element unit as well as physical characteriscs of the heang
agent cause that the boom pipes (especially the two at the very boom of the radiator)
may have a lower temperature than the remaining parts of the radiator – this is a normal
phenomenon.

a short period of me in order to heat up the radiator to the set temperature. Aer
that, it turns itself on and o periodically, using only as much energy as it is required
to maintain the set temperature of the radiator for current external condions.

TIMER Mode is acvated by pressing the buon (yellow diode turns on).
1. TIMER Mode can be used to TURN OFF the device:
Press buon while the device is on – the device will turn o aer 2 hours.
2. TIMER Mode can also be used to TURN the device ON:

the radiator inuence the way in which the heat is distributed – the temperature of the
boom pipes of the radiator (especially the two located at the very boom of the radia-
tor) may be lower than the temperature of the remaining parts of the radiator – this
is a normal phenomenon.
Turning the device on does not mean that it uses the same maximum power for the whole
me it is on. On turning the device on, it operates with the nominal power for a short
period of me in order to heat up the radiator to the set temperature. Aer that it turns
itself on and o periodically, using only as much energy as it is required to maintain the
set temperature of the radiator for current external condions.

When the device is o and temperature around the temperature sensor drops down
below 6°C, the device will switch on automacally. This is to prevent the heang agent
inside the radiator from freezing. Display panel will show AF code.
DRYER MODE
Dryer mode allows to turn the device on for a certain length of me, ie. in order dry
a towel. 
