1 Introduction
ECtemp 530 is an electronic thermostat provided with a
2- pole switch and a wire sensor to measure and control the
desired oor temperature. It can be either ush-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 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
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.
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.

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
5 °C during specied periods.
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. 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
order of disassembly.
4. Turn on the power supply.

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.

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.
