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 1pole switch, and a floor sensor to measure and control the
desired floor temperature. It can also be used with an external room sensor.
The thermostat has a button to adjust the temperature setting 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.

Make sure the mains supply to the thermostat is turned off
before installation.
IMPORTANT: When the thermostat is used to control a

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
DEVIreg™ 233
In wet rooms, place the thermostat according to local regulation on IP classes. Do not
install the thermostat in small bathrooms
with poor ventilation, nor close to the toilet due to the risk of condensed water and
water splash.
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.
Installation Guide 7

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.
