“SMART”
Electronic control for towel radiators
SMART is an electronic thermostat for the automatic control of electric towel
radiators. By means of an internal sensor, it is capable of keeping the temperature
of the towel radiator to a desired value.
Ten different electric resistances are available in a range between 100W and
1000W.
Operative modes: Comfort, Standby/Antifreeze and 2hr Boost
with 12 or 24hr Auto Boost.
“Comfort” mode: The thermostat keeps the internal
temperature at the value set by the user.
“Standby/Antifreeze” mode: In this mode, the device is on
standby. However, as soon as the measured temperature falls
below 10°C, the control system activates the heating element, in
order to prevent the internal liquid from freezing.
“Boost” mode: In “Boost” mode, the heating element is
activated for a period of 2 hours independently of the configured
temperature. The temperature is however automatically
controlled in order not to exceed 65°C. At the end of the 2 hours
period, the device returns to “Comfort” mode.
“Auto Boost” mode: The control system enters into “Boost”
mode for 2 hours. After that, it returns to “Comfort” mode for
10, or 22 hours (period configurable by the user) and then it
enters again into “Boost” mode for 2 hours.
This sequence is repeated endlessly.
SMART is compliant with the following standards:
-Eco-design Directive for Energy-using Products,
2005/32/EC (<0,5W).
-EN 60335-1:2012 -EN 60335-2-30:2011 -EN 60335-2-43:2005

WARNING
RISK OF ELECTRIC SHOCK!
Disconnect power supply before proceeding with installation.
Preserve with care the present instruction sheet and read carefully
before using 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 device (see technical specifications).
•Only use heating elements compatible with the type of used
towel radiator.
•Disconnect power supply before cleaning or before performing
maintenance of the product.
•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 installer only
•Disconnect the device from power supply before proceeding with installation.
•Protect the device with a 30mA RCD circuit breaker.
1) Turn the rail upside down and remove the blank from desirable side.
2) Insert the heating element into the threaded opening.
3) Securely fasten the element to the body of the towel rail with a 22mm wrench. DO NOT
TIGHTEN USING THE ELEMENT HEAD.
4) The special sheath ensures a secure mounting and eventually allows a slight supplemental torsion
to perfectly align the thermostat with the radiator.
5) Turn the rail the correct way around.
6) Securely fasten the rail in position on the wall.
7) Connect the device to mains (this should be done by a qualified electrician). The bleed on the top of
the rail at this point must remain open!
8) Switch the element on at full heat.
9) Remove the expelled liquid (be careful to avoid burns!) in order to keep the thermostat dry and
avoid the liquid reaching the border.
10) After 10 to 15 minutes, close the bleed at the top of the rail with a bleed key, or a screwdriver.
TROUBLE SHOOTING
The top of my radiator isn’t heating properly.
The most likely factor in this is that too much water has escaped during the commissioning of the rail. To resolve this
problem, make sure your radiator has been switched off for a while and is cold. Then, using a 22mm spanner, remove
the blank or bleed at the top of the radiator. If this is not possible, you might have to take the radiator off the wall and
remove the element. Take a look inside to see the level of the solution. If it is below the small lugholes in the collector
bar at the top of the radiator, or below the top bar, you will need to top it up with normal, soft water. If you live in a
“hard water” area, it would be better to use bottled water, to prolong the life of your elements.
When you have topped up the fluid level, turn the radiator back on with the bleed valve open. Leave to heat up for 10
to 15 minutes, then, with either a bleed key or small screwdriver, close the bleed valve.

Electronic control for towel radiators
Press the [On/Standby] button to turn on the device or to enter the “Standby/Antifreeze” mode.
NOTE: When the device is switched to "Standby/Antifreeze" mode, it beeps twice for 0.5sec.
When the device is switched to “On” mode (i.e. it is turned on), it beeps for 1sec.
“Comfort” mode: In this mode the desired temperature of the radiator is selected. The temperature
value is set through the [+] and [-] buttons to one of the following values:
40°C, 45°C, 50°C, 55°C, 60°C, 65°C.
The rightmost lit or blinking LED in the “Comfort bar” indicates the selected temperature. A blinking
LED indicates that the corresponding temperature has not yet been reached during the heating
phase. When a certain temperature level is reached, the corresponding LED stops blinking and
remains lit.
Example: The device is firstly turned on.
Pressing 4 times the [+] button, the
desired temperature is set to a value
of 55°C (the first 4 LEDs from the left
start blinking).
The radiator starts heating. When the
temperature of the radiator reaches
40°C the first (blue) LED stops blinking
and remains lit.
After some time, the temperature
reaches 45°C and the second (green)
LED also stops blinking and remains
lit.
The same behavior applies to the two
subsequent (yellow) LEDs, until the
desired temperature of 55°C is
reached (all LEDs stop blinking).
“Standby/Antifreeze” mode: In this mode the device goes in standby, however as soon as the
temperature of the radiator falls below 10°C, the heating element is automatically powered on.
