MANUAL FOR EB-Therm 55
EB-Therm 55 Thermostat Steering
Thank you for choosing Ebeco. We wish you well with your EB-Therm 55 and
underfloor heating system. We hope that you will use it and enjoy it for many
years to come.
For the guarantee to be valid, the product must be installed and operated as
indicated in this manual. This means it is extremely important that you read
the manual. This applies both to the person installing EB-Therm 55 and the
person who is going to use it. You will also find technical specifications and
information on troubleshooting.
If you have any questions, you are always more than welcome to contact Ebeco.
Call +46 31 707 75 50 or send an e-mail to

Important The underfloor heating system is an electrical power installation and must therefore be installed in accordance with the current regulations and under the supervision of a qualified electrician.
This is EB-Therm 55
EB-Therm 55 is a microprocessor-controlled thermostat for optimum regulation
of underfloor heating systems.
The front is fitted with a lockable knob for regulating temperature, as well
as an on/off switch that shows whether the underfloor heating is in operation.
Temperature control is carried out by means of an algorithm that uses fuzzy
technology. The technology entails EBTherm testing and collecting data from
start-up, and based on this, calculating when to turn on and off.
This technology reduces temperature variations and thus provides a more
constant temperature and lower energy consumption.
The floor temperature varies less than +/- 0.3 degrees.

Manual Quick guide
Installing EB-Therm
The floor sensor should be mounted in a spiral hose laid in the floor. The hose endings should be sealed so that the floor sensor can easily be replaced.
Installation
Mount EB-Therm in a 65 mm standard appliance box.
-
Make sure the box is level with the wall.
-
Remove the knob and undo the screw as in the illustration. Lift off front and frame.
-
Connect power, voltage 230 VAC, load and floor sensor cable.
Any extension to the floor sensor cable must be by means of high-voltage current. Protective conductor for incoming feed and for heating cable is connected with a connection clip in the box. See wiring diagram below. -
Insert the thermostat into the appliance box and screw tight with the existing screws.
-
Read the How the thermostat works/Regulating functions section on how to set the regulating functions.
-
Mount frame, front and knob.
-
If the thermostat is mounted in a multi-compartment frame, the internal corners of this frame must be removed.
Getting started
After installation, wait 2-4 weeks before starting the underfloor heating.
Precisely how long you wait depends on the type of floor you have and the
instructions for the floor putty. Then increase the heat gradually.
In order to adapt the underfloor heating system to your own heating
requirements as much as possible, it is important that you read the entire
manual.
If you have any questions about the use of EB-Therm 55, you are more than
welcome to contact Ebeco. Call +46 31 707 75 50 or send an e-mail to

How EB-Therm works
This section describes all you need to know about how EB-Therm 55 works and how you set it.
Turning EB-Therm off and on
The heating is not controlled in stand- by mode. Depress the on/off switch for
a second to access stand by mode.
Return to normal mode by once again depressing the button for a second.
Control functions
The thermostat can regulate the temperature in three different ways. This
enables the comfort temperature and any flooring temperature requirements to
be combined. How the settings are adjusted is described on the next page.
Room thermostat (R) – The thermostat has built-in sensors for measuring the
room’s temperature and controlling the heating.
Floor thermostat (F) – A sensor in the floor measures the temperature and then
regulates the heating accordingly. This is the factory setting.
Room and floor thermostat (R&F) –
The built-in sensor regulates the room temperature and the sensor in the floor
functions as a floor temperature limiter. The limitation can be set to between
25°C and 45°C. The factory setting is 35 °C.
Important
In rooms with large windows that are exposed to solar insolation, we recommend
the Room and floor thermostat function.
In rooms with wooden flooring, the Roomand floor thermostat function must
always be used.
The adjustment of the regulating function, must be done by a qualified
electrician. The knob and the front first have to be removed. Disconnect from
power supply before removing.
Then slide the control to the required position using a small screwdriver.
R – Room thermostat
F – Floor thermostat
R&F – Room and floor thermostat
Temperature
Regulating function
EB-Therm 55 regulates the temperature via a sensor in the floor that measures
the temperature and regulates the heating accordingly.
Set the temperature required Change the floor temperature by turning the knob.
Min. position on the control corresponds to 10 °C, max. position corresponds
to 45°C. An appropriate setting is usually between 2 and 3.
The temperature does not stabilise until the underfloor heating system has
been on for a few days. It might then be necessary to adjust the thermostat’s
setting.
Indication
The colours on the on/off switch show the current status for EB-Therm.
Red light – the thermostat is on and the underfloor heating is activated.
Green light- the thermostat is on and the underfloor heating is switched off.
Delay between turning off and on There is a built-in delay in order to avoid
unnecessary wear and tear on internal components and to extend the life of the
thermostat. If you raise the desired temperature so that the thermostat comes
on, and then lower it shortly afterwards, then it takes 30 seconds before it
goes off again.
Key lock button
When you have found a suitable setting for the temperature you can lock the
knob. This prevents the control being changed accidentally.
See illustration below. First remove the knob. Then move the two plastic parts
so that they define the interval required. Replace the knob.
Troubleshooting
Important The underfloor heating system is an electrical power installation and any faults must therefore be remedied by a qualified electrician.
Fault indication
If the floor/room sensor is damaged or interrupted, the thermostat will cut
out and the lamp start to flash alternatingly green and red.
If the floor sensor should become faulty, it can be replaced provided it is
installed in a spiral hose laid in the floor as instructed. The room sensor
cannot be replaced. The thermostat must be replaced if there is a fault with
the room sensor.
