3Installation Guide

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.

7Installation Guide

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.

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.

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.
