Installation Guide 3
1 Introduction
DEVIreg™ 532 is an electronic thermostat provided with a
2-pole switch, a room sensor to control the room temperature,
and an additional oor sensor to limit the maximum oor tem-
perature. It can be either ush-mounted or surface-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 o
before installation.
IMPORTANT: When the thermostat is used to control a
oor heating element in connection with a wooden oor or
similar material, always use a oor sensor and never set the
maximum oor temperature to more than 35°C.
Please also note the following:
• The installation of the thermostat must be done by an
authorized and qualied installer according to local
regulations.

Installation Guide6
• 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.
Do not place the thermostat on the inner
side of an exterior wall.
DEVIreg™ 532
Installation Guide 7
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 oor sensor enables a more accurate
temperature control and is recommended
in all oor heating applications
and mandatory under wooden oors to
reduce the risk of over-heating the oor.
• Place the oor 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 ush with the oor surface -
countersink the conduit if necessary.
• Route the conduit to the connection box.
• The bending radius of the conduit must be min 50mm.

The screen of the heating cable must be connected
to the earth conductor of the power supply cable by
using a separate connector.
Note: Always install the oor sensor in a conduit in
the oor.
3. Set the maximum oor temperature between 20 °C
and 50 °C by turning the screw with temperature
indications in the upper left corner.
4. Mount and reassemble the thermostat:
• Fasten the thermostat to a ush-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.

How to change the minimum and maximum oor
temperatures
1. Remove the adjustment button.
2. Move the pins to the desired
positions.
3. Put the adjustment button back
in place.

Note: Please be aware of the following:
• The oor temperature is measured where the oor
sensor is placed.
• The temperature of the bottom of a wooden oor can
be up to 10 degrees higher than the top.
• Floor manufactures often specify the max
temperature on the top surface of the oor (usually
27-28 ˚C).
• By default, the maximum oor temperature is set to
35 °C.
• Always use a oor sensor or a room + oor sensor
combination to control oor heating. Without a oor
sensor, the temperature control may be less accurate
and you risk overheating the oor.
