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.

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.
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

Follow the steps below to mount the thermostat:
1. Open the thermostat:
Detach the front cover by inserting a small screw-
driver in the hole on top of the thermostat and lifting the cover outwards.
Loosen the two screws and carefully detach the unit.
2. Connect the thermostat according to the connection diagram.
Note: Always install the floor sensor in a conduit in the
floor.

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.
