1 Introduction
DEVIreg™ 532 is an electronic thermostat provided with a 2-
pole switch, a room sensor to control the room tempera-
ture, and an additional floor sensor to limit the maximum
floor temperature. It can be either flush-mounted or sur-
face-mounted.
The thermostat has a button for adjusting the temperature
setting with a scale from ( ) 5-35°C. Furthermore, it has a
LED indicator showing standby periods (green light) and
heating periods (red light).

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 (typically 80-170cm.).
In wet rooms, always place the thermostat
according to local regulation on IP classes.

6 Installation Guide

Do not place the thermostat on the inner
side of an exterior wall.
Always install the thermostat at least 50
cm. from windows and doors.
Do not place the thermostat in a way that
it will be exposed to direct sunlight.
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.

Installation Guide 7

▪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.
Follow the steps below to mount the thermostat:
1. Open the thermostat:

The screen of the heating cable must be connected to
the earth conductor of the power supply cable by us-
ing a separate connector.
Note: Always install the floor sensor in a conduit in the
floor.
3. Set the maximum floor temperature between 20˚ and
50˚C by turning the screw with temperature indica-
tions in the upper left corner.
4. Mount and reassemble the thermostat:
▪Fasten the thermostat to a flush-mounting box or a
surface-mounting box by driving the screws through
the holes in each side of the thermostat.
▪Install the frame and front cover in the reverse order
of disassembly.
5. Turn on the power supply.

Note Please be aware of the following:
▪The floor temperature is measured where the floor
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).
▪By default, the maximum floor temperature is set to
35°C.
▪Always use a floor sensor or a room + floor sensor
combination to control floor heating. Without a floor
sensor, the temperature control may be less accurate
and you risk overheating the floor.
