3Installation Guide
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.

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.

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.
