1 Introduction

The ECtemp 550 thermostat controls electrical floor heat­ing elements using a built-in and/or an external tempera­ture sensor. The thermostat can be optimised for the room within a few days after the installation by continuously col­lecting 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.

1.2 Safety Instructions

Make sure the mains supply to the thermostat is turned off before installation. If the thermostat is installed in a net­work, 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
ECtemp 550

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
ECtemp 550
Do not place the thermostat in a way that it will be exposed to direct sunlight.
Note: A floor sensor enables a more accu­rate temperature control and is recom­mended 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
ECtemp 550
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 con­nector plug on the back of the module.
Carefully detach the frame.

2. Connect the thermostat according to the connection
diagram.
The screen of the heating cable must be connected to the earth conductor of the power supply cable by us­ing a separate connector.
The devinet terminals are used when connecting ther­mostats 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.

3. Mount and reassemble the thermostat.
= Screw holes for mount and reassemble the ther-
mostat.
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, display module, and front cover in
the reverse order of disassembly. Make sure to carefully put the display module in place and do not over-tighten the screws.
4. Turn on the power supply.
Initially main supply the thermostat for 15 hours to fully charge the battery. The current time and day is then kept for 100 hours if mains supply is off. All other settings are stored permanently.

How to enter the basic configuration settings
1. Press and hold the button for 12 seconds
until “COdE” appears.
2. Turn the button clockwise until “0044”
appears.
3. Press the button once to confirm.
Network: How to specify whether you want to connect this thermostat with other thermostats in a network
Please note that the slave units must be connected to the master unit using the devinet terminals.
1. Define the thermostat as independent, master or
slave unit.
To define this unit as an independent unit or if network is not used, choose ALO.
To define this unit as the master unit in the network, choose MAS.
Installation Guide 15
ECtemp 550
To define this unit as a slave unit in the network, choose SLA.
Only one unit in the network can be defined as master
unit. All slave units will respond to and send informa­tion to the master unit. Time, day of week and econo­my periods will be controlled from the master unit. All other settings must be specified for each slave unit. No more than 32 units can be combined in a network including independent units (even though these units do not communicate with the master unit).
2. Press the button once to confirm your selection.

Adaptive regulation: How to specify whether or not to optimise this thermostat for the room by timing heat­ing start/stop
1. Turn the adaptive function on or off.
To let the unit continuously collect updated room data, choose AdAP. This means improved performance (with compensa­tion for e.g. sudden temperature drops in the room) and precise timing so the selected temperature is ach­ieved at the desired time.
To turn off the adaptive function, choose OFF This means that the heating will not start/stop until the specified time.
2. Press the button once to confirm your selection.

ECtemp 550
Sensor: How to specify whether an external floor sen­sor, the built-in room sensor or both is used to control the floor heating
1. Turn the button to choose one of the following sensor
settings: If both a room sensor and a floor sensor is
used, choose rFS. This option is suitable for all rooms but wet rooms. The thermostat must be in­stalled in the same room as the floor sen­sor and the heating elements.
If only a floor sensor is used, choose FS. The built-in room sensor is not used. This option is suitable for rooms in which a constant floor temperature is required, e.g. in a bathroom.
If only a room sensor is used, choose r S. This option is not recommendable due to an increased risk of overheating the floor. The thermostat must be installed in the same room as the heating elements.
2. Press the button once to confirm your selection.
18 Installation Guide
ECtemp 550
How to set the maximum floor temperature Special condition: This setting only applies if a floor sen-
sor is used (the FS or rFS sensor option has been set).
1. Turn the button to change the tempera-
ture.
2. Press the button once to confirm your se-
lection.
Note: Please contact the floor supplier before changing the maximum floor temperature and be aware of the following:
The floor temperature is measured where the sensor is
placed. The temperature of the bottom of a wooden floor can
be up to 10 degrees higher than the top. Floor manufactures often specify the max. tempera-
ture on the top surface of the floor.

lowering the temperature by no more than approx 5 °C. By default, the temperature decrease is set to -5 °C
1. Turn the button to set the setback level. For example, choose -4 °C to lower the temperature by 4 degrees.
2. Press the button once to confirm your se­lection. The display returns to normal.
