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.

DEVIreg™ 532

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.

3 Settings

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.

devireg™550

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.
