Place the thermostat at a suitable height on the wall

(typically 80-170 cm.). Switch can be placed on free

area on the wall.

The thermostat/switch should not be placed in wet

rooms. Thermostat/switch must be placed outside

zone 2. Place it in an adjacent room and use ﬂoor

sensor only. Always place the thermostat/switch

according to local regulation on IP classes.

Do not place the thermostat on the inner side of a

poorly insulated exterior wall.

Always install the thermostat at least 50 cm from

windows and doors, due to draft, when using regu-

lation in: ﬂoor and room mode or room alone mode.

9Installation Guide

Note for thermostat: A ﬂoor sensor is recommend-

ed in all ﬂoor heating applications and mandatory

to thin mats and under wooden ﬂoors to reduce the

risk of over-heating the ﬂoor.

• Place the ﬂoor sensor in a protecting plastic conduit

in the ﬂoor construction in an appropriate place,

where the ﬂoor is not exposed to sunlight or draft

from door openings.

• Equally distant and >2 cm from the heating cables

on both sides.

• The conduit should

be ﬂush with the ﬂoor

surface, countersink

the conduit if neces-

sary and possible.

• Route the conduit to

the connection box.

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