SMART THERMOSTATIC
ELECTRONIC CONTROL FOR TOWEL RADIATORS
SMART Thermostatic is an electronic thermostat for the automatic control
of electric towel radiators. Using 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, Stand-by/Antifreeze, Boost 2h, P1, P2.
• Comfort mode: The thermostat keeps the towel radiators temperature
at the level set by the user.
• Boost 2h mode: the heating element is activated for a period of 2
hours independently of the configured temperature. The temperature is
automatically control LED so as not to exceed 65°C. At the end of the 2
hour period, the device returns to “Comfort” mode.
• P1 and P2 mode: The control system enters “Boost” mode for 2
hours; after that it returns into “Comfort” mode for 22 or 10 hours
(configurable by the user P1 or P2) and then it enters again into “Boost”
mode for 2 hours, repeating the same procedure endlessly.
• Standby/Antifreeze mode: if the temperature drops below 10°C the
device will automatically active the control system in order the internal
liquid freezing Available colours:

WARNING
RISK OF ELECTRIC SHOCK!
DISCONNECT POWER SUPPLY BEFORE PROCEEDING WITH INSTALLATION.
Please read carefully before using the device.
• The present device has been designed for exclusive use on a towel radiator.
• The thermostat in combination with a heating element is designed for heating the liquid contained inside a towel
radiator. 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 power supply before cleaning or before performing maintenance of the product.
• In case of damage to the supply cable, turn off the device and do not touch. The damaged power supply cables
can be replaced by the manufacturer or by an authorised service centre. Failure to either adheres to the above
rules could lead to compromised system safety and invalidate the warranty.
• Store 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 installers only
• Disconnect the device from power supply before proceeding with installation or maintenance.
• Protect the device with a 30mA RCD circuit breaker and an isolating switch to disconnect from.
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 mounting and 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, DO NOT 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
additional 5 minutes then stop heating.
11. If necessary, top up the radiator before the liquid cools
down (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.

Press the [On/Standby] button to turn on the device or to enter the “Standby/Antifreeze” mode.
NOTE:
The device will beep twice for 0.5 seconds when put into “Standby/Antifreeze” mode. The device will beep once for
1 second when turned on.
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.
Turn on the device. 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.
The temperature rises above 40°C
And so forth, to reach the LED that
indicates 55°C. When all the LEDs stop
blinking, the radiator has reached the
desired temperature.
