Electronic control for towel radiators

• Disconnect power supply before installation.

• Connection of the device to the electric resistance must be performed by authorized personnel only.

• Make sure that the power of the electric resistance does not exceed the maximum power allowed by the electroni

control device.

1. Make sure that the towel radiator does not have leakage or air lock.

2. The device shall not be positioned directly in front of an electric plug.

3. Prevent water jets from hitting the equipment.

4. Connect the temperature controller only to a suitable heating element.

5. Ensure that the mains voltage is the same as indicated in the technical specifications.

6. Make sure that the type of electric resistance is compatible with the model of towel radiator being used

(check the product specifications provided by the manufacturer). The usage of a heating element with
higher power:

- Does not increase the actual power of the towel radiator;

- Might shorten life of the heating element;

- Could damage the equipment.

7. Make sure that the power of the electric resistance does not exceed the maximum power of the towel

radiator (check the label on the heating element).

8. When installed in a room with bathtub or shower, respect the “Protection Zones” according to IP44

insulation class (in UK according to IEE cabling directives). Furthermore, make sure to respect all local
safety directives.

9. The device has to be protected by a 30mA circuit breaker (RCD).

10. Power the device with the recommended voltage (see technical specifications).

11. If a device is directly connected to a fixed electric installation, install an isolating switch compliant with

local directives for power supply disconnection.

12. Place the "O-Ring" before the fastening area.

13. After ensuring that the "O-Ring" is correctly positioned, screw the electric resistance in the relevant

threaded hole of the towel radiator, properly secure it and insert the cover ring.

14. Extract the connecting cables from the device. The four poles connector and the ground connector (only

Class I).

15. Connect the 2 Faston connectors to the corresponding connectors of the heating element.

16. Connect the female Faston connector to Earth (only Class I).

17. Insert the lower part of the heating element into the ready connected thermostat.

18. Align the device to the towel radiator. Warning! Do not rotate the device more than 30 degrees on

both directions.

19. Push the device against the base of the heating element to compress the “O-Ring”, properly fix the

related fastener so that the device remains well secured and does not rotate around the heating element.

20. Connect the power supply cable.

1. A Thesis Digital device supporting "Fil-Pilote" functionality(classeII) can be remotely
controlled by a control unit supporting the "Fil-Pilote" system. The brown wire is the Live

wire (L), the gray wire is the Neutral wire (N) and the black wire is used for receiving the
Fil-Pilote signal.

Do not connect the black wire to the Earth.

2. A Thesis Digital device without "Fil-Pilote" functionality (Class I) cannot be remotely

controlled. The brown wire is the Live wire (L), the blue wire is the Neutral wire (N)
and the yellow/green wire has to be connected to Earth.

OPERATION

The [On/Stand-by] button (1) is used to turn on the device or to enter the "Standby" mode. A red light (11) indicates
that the device is turned on; a blue light (11) indicates that the device is in "Standby" mode.

NOTE: When the device goes into “Stand-by” mode it beeps twice for 0.5s.
When the device is activated it beeps once for 1s

THERMOSTAT MODE

In this operative mode the user can set the desired room temperature through the [+] and [-] buttons (7) in a range

etween 10°C and 32°C. The external sensor (4) is used in this mode for detecting the room temperature and allows the
automatic temperature control.
If the selected temperature is higher than the room temperature, the active heating indication icon (9) is shown on the

display and the heating element is being powered until the room temperature reaches the selected temperature value.
When the room temperature reaches the desired value, the heating element is switched off and the active heating
indication icon (9) is turned off on the display.

SUB-FUNCTIONS

Fil-Pilote

The 4 sub-functions above can be selected through the [Mode] button(6).

"Comfort" - Icon "sun" (10); it is the default function (already described above).

ht" - Icon “moon” (10); it is similar to the "Comfort" function, but the temperature range is between +9°C

"Ni

and 31°C.

NOTE: The “Night” temperature is always be low the “Comfort” temperature. The “Comfort” temperature can thus be

set in a range between the currently set “Night” temperature + 1°C and 32°C, and analogously the “Night” temperature

can be set between 9°C and the currently set "Comfort" temperature.
"Antifreeze" - Icon “snow flake” (10); the temperature remains fixed to 7°C.

icon is shown on the display.
(This functionality is only available for products equipped with "Fil-Pilote" connectivity)
This sub-function allows managing the device by a central control system that sets the operating mode for each of
the connected devices.
The device even recognizes the most advanced 6-commands based "Fil-Pilote" system that allows the execution of
the following functions:

1. Standby: power off the heating element, the device remains active.

2. Comfort: maintains the "Comfort" temperature set by the user.

3. ECO: maintains the room temperature 3,5°C below the "Comfort" temperature.

4. Anti-freeze: maintains the room temperature at 7°C.

5. Eco-1: maintains the room temperature 1°C below the "Comfort" temperature.

6. Eco-2: maintains the room temperature 2°C below the "Comfort" temperature

TIMER MODE

This operating mode can be accessed through the [Select] button (5). By repeatedly pressing this button it is
possible to select between the following options:

1.

Enter the "Timer-2h" sub-function.

2.

Enter the "2h-repeated" sub-function.

3.

Exit any of the previous sub-functions.

TIMER-2H: "Timer-2h" LED (3) is turned on.

The device powers the heating element for 2 hours independently of the room temperature. At the end of the 2
hours period the device returns to the previous operating mode and the “Timer-2h” LED (3) is turned off. Press
the [Select] button (5) twice to deactivate the "Timer-2h" sub-function. Both LEDs (3) and (2) should appear
turned off.

2H-REPEATED: "2h-repeated" LED (2) and "Timer-2h" LED (3) are turned on.

The device powers the heating element for 2 hours independently of the room temperature. At the end of the 2
hours period the device returns to the previous operating mode and the “Timer-2h” LED (3) is turned off.
The procedure is then repeated every day endlessly. Press the [Select] button (5) to deactivate this sub-function.
Both LEDs (3) and (2) should appear turned off.

NOTE. In “Timer-2h” and “2h-repeated” modes, the maximal temperature is automatically limited to 32°C.

STANDBY:

In "Standby" mode the heating element is powered off.

KEY LOCK

Press together [Select] (5) and [Mode] (6) buttons for 5 seconds to lock all the buttons (except the
[On/Stand-by] button). When key lock is activated, a “LO” indication is displayed on the screen.
