1 Introduction

DEVIreg™ Touch is an electronic programmable timer
thermostat used for controlling electrical floor heating
elements. The thermostat is designed for fixed installation
only and can be used for both direct heating of the entire
room and for comfort heating of the floor. Among others,
the thermostat has the following features:

• A touchscreen display with backlight.

• An easy-to-follow menu-driven programming and
operation.

3Installation Guide

DEVIreg™ Touch

• An installation wizard with room/floor type-specific
setup.

• Support for multiple frame systems.

• Compatible with several 3rd party NTC sensors.

• Thermostat settings can be specified before instal­lation and imported to the thermostat using a
web-generated code, or copied from a thermostat in a
similar installation.

• Smart access to thermostat settings after installa­tion by using a web code interface for easy setup or
remote troubleshooting.

Electrical safety and Electro-Magnetic Compatibility for
this product is covered by the compliance with the EN/IEC
Standard “Automatic electrical controls for household and
similar use”:

• EN/IEC 60730-1 (general)

• EN/IEC 60730-2-9 (thermostat)

1�2 Safety Instructions

Make sure the mains supply to the thermostat is turned off
before installation.

Important: When the thermostat is used to control a floor
heating element in connection with a wooden floor or
similar material, always use a floor sensor and never set the
maximum floor temperature to more than 35°C.

Please also note the following:

• The installation of the thermostat must be done by an
authorized and qualified installer according to local
regulations.

Installation Guide6

DEVIreg™ Touch

• The thermostat must be connected to a power supply
via an all-pole disconnection switch.

• Always connect the thermostat to continuous power
supply.

• Do not expose the thermostat to moisture, water,
dust, and excessive heat.

2 Mounting Instructions

Please observe the following placement guidelines:

Place the thermostat at a suitable height on the wall
(typically 80-170cm.).

The thermostat should not be placed in wet rooms.
Place it in an adjacent room. Always place the ther­mostat according to local regulation on IP classes.

Do not place the thermostat on the inner side of an
exterior wall.

Always install the thermostat at least 50 cm. from
windows and doors.

7Installation Guide

DEVIreg™ Touch

Do not place the thermostat in a way that it will be
exposed to direct sunlight.

Note: A floor sensor enables a more accurate
temperature control and is recommended in all floor
heating applications and mandatory under wooden
floors to reduce the risk of over-heating the floor.

Place the floor sensor in a conduit in an appropriate place
where it is not exposed to sunlight or draft from door openings.

• Equally distant and >2cm from two heating cables.

• The conduit should be flush with the floor surface -
countersink the conduit if necessary.

• Route the conduit to the connection box.

• The bending radius of the conduit must be min 50mm.

3�2 Forecast

The forecast feature is used when you switch between
economy temperature and comfort temperature. If forecast
is turned on, heating will start so that the requested tem­perature is reached at the specified time.

For example, if your comfort temperature is set to 22°C and
the comfort period starts at 6.00 o’clock am, heating will
start before 6 o’clock so that your room temperature will be
22°C at 6 o’clock. If forecast is turned off, heating will not
start until 6 o’clock and it will take a while to reach a room
temperature of 22°C.

The forecast feature also optimises heating stop when switch­ing from comfort temperature to economy temperature.

17Installation Guide

DEVIreg™ Touch

If you break the small plastic seal
on the back of the display mod­ule, e.g. using a screwdriver, it will
be possible to set the maximum
floor temperature up to 45°C.

Furthermore, it will be possible to
use only a room sensor. However,
this option is not recommendable due to an increased risk
of overheating the floor.

Important: When the thermostat is used to control a floor
heating element in connection with a wooden floor or
similar material, always use a floor sensor and never set the
maximum floor temperature to more than 35°C.

Note: Please contact the floor supplier before changing the
maximum floor temperature and be aware of the following:

• The floor temperature is measured where the sensor
is placed.

• The temperature of the bottom of a wooden floor can
be up to 10 degrees higher than the top.

• Floor manufactures often specify the max. tempera­ture on the top surface of the floor.
