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.

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.
