1 Introduction
ECtemp 530 is an electronic thermostat provided with a 2-
pole switch and a wire sensor to measure and control the
desired floor temperature. It can be either flush-mounted
(standard) or surface-mounted (using special box).
The thermostat has a button for adjusting the temperature
setting with a scale from ( ) 1 to 6 (each step corresponds
to approximately 8°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 off
before installation.
IMPORTANT: When the thermostat is used to control a
floor heating element in connection with a wooden floor or
similar material, always use a floor sensor and never set the
maximum floor temperature to more than 35°C.

Installation Guide 5

Please also note the following:
▪The installation of the thermostat must be done by an
authorized and qualified 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
Place the thermostat at a suitable height
on the wall (typically 80-170cm.).
In wet rooms, place the thermostat accord-
ing to local regulation on IP classes.

6 Installation Guide

Note: A floor sensor enables a more accu-
rate temperature control and is recom-
mended in all floor heating applications
and mandatory under wooden floors to
reduce the risk of over-heating the floor.
▪Place the floor 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 flush with the floor surface -
countersink the conduit if necessary.
▪Route the conduit to the connection box.
▪The bending radius of the conduit must be min
50mm.

By connecting an external timer to the terminal
marked by a moon symbol (and by using for example
the same phase as for the mains power supply), the
thermostat can be set to reduce the temperature by
5ºC during specified periods.
The screen of the heating cable must be connected to
the earth conductor of the power supply cable by us-
ing a separate connector.
Note: Always install the floor sensor in a conduit in the
floor.

3. Mount and reassemble the thermostat.
▪Fasten the thermostat to a socket or an exterior
wall box by driving the screws through the holes
in each side of the thermostat.
▪Install the frame and front cover in the reverse or-
der of disassembly.
4. Turn on the power supply.
