lectronic control for towel radiators
'SMART 43 ' is an electronic control for
towel radiators.
There are ten different types of available
resistances:from100Wto1000W.
Operational modes:
Continuous-Heating,Stand-by,
Boost,Timer12,Timer24.
• “Continuous-Heating”: the electronic
control activates the heating element and
remains active until the user decides to set
the device in “Stand-by” mode. The maximum
temperature of work is 43°C
• “Boost” mode: the thermostat feeds the
heating element at the maximal power for
two hours. At the end of the two hours, the
control goes back into the “Stand-by”
mode. The tem
p
erature of work is 43°C
• “Timer12”and“Timer 24” mode: the
electronic control activates the “Boost”
function for two hours. At the end of the two
hours the control enters into “Stand-by”
mode for either 10 or 22 hours (the user
has the possibility to preset it), after which
the thermostat repeats the function “Boost”
for two hours. This sequence is repeated

Warning
Risk of electric shock
Disconnect the power supply before proceeding with
the installation
Preserve with care the present instruction sheet and read carefully before
usin
g
the device.
• The present device has been designed for exclusive use on a towel
radiator.
• The thermostat is designed for heating the liquid contained inside a towel
radiator in combination with a heating element. Any other use is forbidden.
• Before using, carefully ensure that the line voltage is the same as that
specified for the thermostat (see technical specifications).
• Only use heating elements compatible with the type of used towel
radiator
• Disconnect the power supply before cleaning or before performing
• In case of damage of the power supply cable shut down the device and do not
tamper with it. The damaged power supply cables can be replaced exclusively
by the manufacturer or by an authorized service center. Failure to comply with
the above rules could lead to compromised system safety and void the
warranty.
• Store and transport the heating element exclusively in the protecting
packaging.
• Replacement of the heating element can be done exclusively by the
product manufacturer.

Installation Guide
To be used by the installer only
• Disconnect the device from power supply before proceeding with installation or maintenance.
• Protect the device with a 30mA RCD circuit breake
r
1) Insert the heating element in the threaded opening located on the bottom part of the radiator.
2) Securely fasten the electric resistance to the body of the towel radiator with a 22mm wrench.
3) The special sheath ensures a secure mountingand eventually allows a slight supplemental torsion to
perfectly align the thermostat with the radiator.
4) Tilt the radiator as in fig. 3, making sure that the opening on top of the radiator is located on the highest
side. WARNING. Donot lean the radiator on the electronic control!
5) Fill the radiator with the specific liquid.
6) Put the radiator back in vertical position and check the internal level of the liquid (fig. 4).
7) Ensure a proper fastening of the heating element in the radiator.
8) Connect the device to mains and start heating (the top opening of the radiator must remain open!).
9) Set the maximal temperature and check the level of the internal liquid.
- Due to thermal expansion the liquid could brim over the radiator.
- Remove the exceeding liquid (be careful to avoid burns!) in order to keep the thermostat dry and avoid
the liquid reaching the border.
10) When the level of the liquid stops growing wait for addition
a
5 minutes then stop heating.
11) If necessary, top up the radiator before the liquid cools do
w
(keep the temperature of the internal liquid checked all the
time).
12) Close the top opening of the radiator with the appropriate
cap.
13) Hook the radiator to the wall.
14) Connect the device to the mains. For models having no
plug it is necessary to install a suitable omnipolar
disconnection switch ensuring complete disconnection in
case of category III overvoltage (that means a switch with
at least 3 mm of space between open contacts).
