1 Introduction
DEVIreg™ 233 is an electronic thermostat designed to be
flush-mounted or wall-mounted in an installation box from
the LK FUGA series. The thermostat is provided with a 1-
pole switch, and a floor sensor to measure and control the
desired floor temperature. It can also be used with an exter-
nal room sensor.
The thermostat has a button to adjust the temperature set-
ting with a scale from (0) 1 to 6 (each step corresponds to
approximately 8°C). Furthermore, the thermostat has an
LED indicator showing standby and heating periods.

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.

Installation Guide 5

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.
▪The sensor is to be considered as live voltage. Have
this in mind if the sensor must be extended.
▪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.

6 Installation Guide

In wet rooms, place the thermostat accord-
ing to local regulation on IP classes. Do not
install the thermostat in small bathrooms
with poor ventilation, nor close to the toi-
let due to the risk of condensed water and
water splash.
Note: A floor sensor enables a more accu-
rate temperature control and is recom-
mended 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.

3. Mount and reassemble the thermostat.
The thermostat is to be installed in a flush-mounting
box or a surface-mounting box for the FUGA design.
▪Put the unit back in place and tighten the screws in
each side to fasten the thermostat.
▪Press the front cover back in place.
4. Turn on the power supply.
3 Settings
Please be aware of the following:
▪The floor temperature is measured where the sensor is
placed.
▪The temperature of the bottom of a wooden floor can
be up to 10 degrees higher than the top.
▪Floor manufactures often specify the max temperature
on the top surface of the floor (usually 27-28˚C).
▪Always use a floor sensor to control floor heating.
