1.2 Safety Instructions
Make sure the mains supply to the thermostat is turned o
before installation.
IMPORTANT: When the thermostat is used to control a
oor heating element in connection with a wooden oor or
similar material, always use a oor sensor and never set the
maximum oor temperature to more than 35°C.
Please also note the following:
• The installation of the thermostat must be done by an
authorized and qualied installer according to local
regulations.
• 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.
Do not place the thermostat in a way that it
will be exposed to direct sunlight.

9Installation Guide
Note: A oor sensor enables a more accurate
temperature control and is recommended in
all oor heating applications and mandatory
under wooden oors to reduce the risk of
over-heating the oor.
• Place the oor 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 ush with the oor surface -
countersink the conduit if necessary.
• Route the conduit to the connection box.
• The bending radius of the conduit must be min 50mm.

is turned on, heating will start so that the requested tem-
perature is reached at the specied 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 o, 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

IMPORTANT: When the thermostat is used to control a
oor heating element in connection with a wooden oor or
similar material, always use a oor sensor and never set the
maximum oor temperature to more than 35°C.
Note: Please contact the oor supplier before changing the
maximum oor temperature and be aware of the following:
• The oor temperature is measured where the sensor
is placed.
• The temperature of the bottom of a wooden oor can
be up to 10 degrees higher than the top.
• Floor manufactures often specify the max. tempera-
ture on the top surface of the oor.
