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.

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.
