1 Introduction

The ECtemp 550 thermostat controls electrical floor heat-

ing elements using a built-in and/or an external tempera-

ture sensor. The thermostat can be optimised for the room

within a few days after the installation by continuously col-

lecting updated temperature data. This will enable the unit

to compensate for sudden temperature changes and

makes it possible to achieve the selected temperature at

the right time.

Furthermore, the unit is able to automatically lower or raise

the temperature at specific points of time, i.e. automatically

switch between comfort and economy temperature.

Installation Guide 5

1.2 Safety Instructions

Make sure the mains supply to the thermostat is turned off

before installation. If the thermostat is installed in a net-

work, the mains supply to all thermostats in the network

must be off.

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.

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.

6 Installation Guide

2 Mounting Instructions

Please observe the following placement guidelines:

Place the thermostat at a suitable height

on the wall (typically 80-170cm.).

The thermostat should not be placed in

wet rooms. Place it in an adjacent room.

Always place the thermostat according to

local regulation on IP classes.

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.

Installation Guide 7

Do not place the thermostat in a way that

it will be exposed to direct sunlight.

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.

8 Installation Guide

Follow the steps below to mount the thermostat:

1. Open the thermostat:

▪Push down the release tab.

▪Carefully detach the front cover.

▪Remove the two screws.

▪Carefully detach the display module. Make sure to

pull it straight out to avoid damaging the 8-pin con-

nector plug on the back of the module.

▪Carefully detach the frame.

The screen of the heating cable must be connected to

the earth conductor of the power supply cable by us-

ing a separate connector.

The devinet terminals are used when connecting ther-

mostats in a network. Network cables must be of

identical isolation value as normal installation cables

and have a recommendable specification of

2x1,5mm2 and a total length of maximum 100m.

Note: Always install the floor sensor in a conduit in the

floor.
