1 Introduction

ECtemp 532 is an electronic thermostat provided with a

2-pole switch, a room sensor to control the room tempera-

ture, and an additional oor sensor to limit the maximum

oor temperature. 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.

Installation Guide6

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.

7Installation 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 oor sensor enables a more

accurate temperature control and is recom-

mended 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.

Installation Guide8

Follow the steps below to mount the thermostat:

1. Open the thermostat:

• Press the release tab in the bottom of the ther-

mostat using a at object.

• Carefully detach the front cover.

• Carefully detach the frame.

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° 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 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 adjust-

ment 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 tempera-

ture 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.
