3 Safety Instructions

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.

Installation Guide

DEVIreg™ Opti

Make sure the mains supply to the thermostat is turned off before installation.

Please also note the following:

•The installation of the thermostat must be done by an authorized and qualified 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.

•This thermostat 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.

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

•Cleaning and user maintenance shall not be made by children without supervision.

4 Mounting Instructions

Please observe the following placement guidelines:

Place the thermostat at a suitable height on the wall (typically 80-170 cm.).

The thermostat should not be placed in wet rooms. Thermostat must be placed outside zone 2. Place it in an adjacent room and use floor sensor only. Always place the thermostat according to local regulation on IP classes.

Do not place the thermostat on the inner side of a poorly insulated exterior wall.

Installation Guide

DEVIreg™ Opti

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.

Note: A floor sensor is recommended in all floor heating applications and mandatory to thin matsand under wooden floors to reduce the risk of overheating the floor.

• Place the floor sensor
in a protecting plastic	1	2
conduit in the floor	1	2

propriate 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.

8	Installation Guide

DEVIreg™ Opti

•The conduit should be flush with the floor surface, countersink the conduit if necessary and possible.

•Route the conduit to the connection box.

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

Follow the steps below to mount the thermostat:

1.Unpack thermostat

2.Remove the front cover as showed on Pic. 1.

3.Connect the thermostat according to the connection diagram.

The screen of the heating cable must be connected to the earth conductor of the power supply cable by using a separate connector.
