3 Safety Instructions

Make sure the mains supply to the thermostat/switch 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/switch must be done by an authorized and qualified installer according to local regulations.

6	Installation Guide

DEVIreg™ Smart

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

•Always connect the thermostat/switch to continuous power supply.

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

•This thermostat/switch can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge, if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved, by a person responsible for their safety.

•DEVIreg™ Smart can modified to work as a timer on/ off switch by downloading new software with new functionality.

•Children should be supervised to ensure that they do not play with the thermostat/switch.

•Switch is designed for permanent operation.

4 Mounting Instructions

Please observe the following placement guidelines:

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

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

8	Installation Guide

DEVIreg™ Smart

Note for thermostat: A floor sensor is recommended 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	1	2

both sides.

• The conduit should

be flush with the	≥
floor surface, coun-
tersink the conduit
if necessary and
possible.

•Route the conduit to the connection box.

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