DEVIreg™ 532
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 qualied 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.
Do not place the thermostat on the inner
side of an exterior wall.

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.

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.
