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.

DEVIreg™ Touch
7Installation Guide
• 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 ther-
mostat 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.

DEVIreg™ Touch
Installation Guide8
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 tem-
perature 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 switch-
ing from comfort temperature to economy temperature.

If you break the small plastic seal
on the back of the display mod-
ule, 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. tempera-
ture on the top surface of the floor.
