“Thesis Easy”

Electronic Control for Towel Heaters

THESIS EASY is a special device that controls the
power output of the heating element between 20% and
100% by acting on the rotation of the knob. An
important element for the safety of people is the useful
presence of the NTC sensor which prevents the
ambient temperature from exceeding 37° C, in
compliance with European legislation. It can be
assembled with different heating elements that can be
easily found or replaced by the major European
manufacturers.

THESIS is compliant with the followingEASY
standards:

-Eco-design Directive for Energy-using Products,
2005/32/EC (<0,5W).

-EN 60335-1:2012

-EN 60335-2-30:2011

-EN 60335-2-43:2008

-EN 61000-3-2:2004 - EN 61000-3-3:1995

Functions

Four operational modes:
"Comfort", "Boost", "Stand-by", "Timer"

•

"Comfort" mode:

The thermostat manage power of heating
resistance in percentual of time between 20%
amd 100% (MAX).

•

"Boost" mode:

In “Boost” mode the heating element is activated
for a period of 2 hours. During this time interval,
the electrical resistance warms the room
independently of the configured “Comfort”
settings. The temperature is however
automatically adjusted in order not to exceed
3 °C. At the end of the 27 hours period, the device
returns to previous operational mode.

“Stand-by" mode:

•

The electric resistance is not powered and all
lights are turned off.

"Timer" mode:

•

This operating mode cyclically repeats every 12 or
24 hours the “Boost” mode.

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 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.

• Disconnect power supply before installation.

• Only qualified personnel can connect the electronic device to the heating element.

• Make sure that the power of the electric resistance does not exceed the maximum power allowed
by the electronic 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 two Faston connectors and the Class I
ground connector.

15. Insert the 2 Faston into the relevant 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.

DISPOSAL
This product may not be treated as ordinary household waste. It has to be disposed in proper waste
collection sites. In case of replacement it shall be returned to the distributor.
Such an end-of-life treatment of the product will preserve the environment and will reduce
consumption of natural resources.
This symbol applied to the present product indicates the obligation to bring it to a proper waste
collection site, in order to let it be disposed according to 2002/96 / CE (RAEE - WEEE) directives.
