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 205

EB-Therm 205 is a microprocessorcontrolled thermostat with LCD display. The display has dimmed background lighting which lights up fully by pressing any button. The display stays lit for 30 seconds after the last button pressed. The front is fitted with an on/ off button and three control buttons.

There are two temperature reduction programs to choose from for energysmart heating.

Temperature control is carried out by means of an algorithm that uses fuzzy technology. The technology entails EB-Therm 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.

Installing EB-Therm

Important EB-Therm must not be installed where it may be exposed to the following:

direct sunlight and draughts.
extreme fluctuations in temperature or high air humidity.

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. All tubes leading into the appliance box must be sealed so that the air temperature sensor cannot be affected by draughts.

Installation
Mount EB-Therm in a 65mm standard appliance box.

Make sure the box is level with the wall.
Take off the front and frame by pressing in the latch on the righthand side with a screwdriver or similar tool, as shown in the illustration.
Connect power, voltage 230 VAC, load and any floor sensor cable. Any extension to the floor sensor cable must be by means of high-voltage current. Protective conductors for the incoming feed and for the heating cable are 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.
Fit the frame and front.
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 filler. Then increase the heat gradually. This does not apply to those who have laid a wooden/ laminate floor on the floor heating.

There is a quick guide that helps you to get started easily with EB-Therm 205. You will find it in the package. The guide describes the most important functions and settings.

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.

How EB-Therm works

This section describes all you need to know about how EB-Therm 205 works. To learn how to enter settings to suit your own requirements, read the How to set EB-Therm section.
How EB-Therm works

Display
The light in the LCD display is fully lit when you press any button, and remains lit for 30 seconds after the last button pressed. The light then dims again. It is possible to set the display to turn the light off entirely. This is described in the How to set EB-Therm/Light section.

If the display is empty, it means that the thermostat is turned off or that it is not connected to the power supply.

When EB-Therm is started for the firsttime the display shows the factory settings as shown in the illustration. How to enter personal settings is described in the How to set EB-Therm section.

There is an explanation of the symbols on the display in the Symbols section.

Using the buttons
The buttons are used to raise and lower the temperature as well as to scroll the menus.

You access the menus by pressing the selection button, . Use the arrows to scroll to a menu option and then confirm with to select it. The menu system is a scrolling system, in other words you come to all submenus regardless of the direction you scroll.

If you want to exit a menu, scroll until the display shows END. Then press the selection button . You can also wait for 30 seconds and the menu exits automatically. How to navigate the menus is described in the How to set EB- Therm section.

Turning EB-Therm on and off Keep the on/off button pressed for one second to get to standby mode. Return to normal mode by once again pressing the button for a second.

The heating cannot be controlled in standby mode. The clock runs as normal, and selected programmes and set temperatures are stored in the memory.

Locking the keypad
The keypad can be locked to prevent anyone touching the buttons by mistake. This is shown with the LOCK symbol in the display

Press and scroll to LOCK. Confirm with to lock.

Unlock by holding down both arrows until the LOCK symbol has disappeared.

Temperature
Displaying current temperature (actual value)
Lock the keypad first. Press . The light will come on and the current temperature in the floor (F) is displayed.

This is the case if the thermostat is set to Floor thermostat. Otherwise the actual temperature (R) in the room is displayed. The temperature is shown for 30 seconds after the last button pressed.

Time and date
Time is set in 24-hour format. The correct day of the week is worked out automatically. The calendar resets itself in leap years and adapts to DST. Read how to set the correct time and date in the How to set EBTherm/Time and date section.

Adaptive function
EB-Therm has a function which works out when the heating should start to give the correct temperature at the correct time. It is activated on delivery, but can be turned off:

Press and scroll to SE T. Select with . Scroll to AF, select with . Scroll between ON/OFF, then confirm with .

Ventilation mode
If the room temperature falls by more than 3°C in a single minute, e.g. when airing the room, the ventilation mode is activated.

EB-Therm will then stop heating for 15 minutes before returning to normal mode. This function is always active.

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, it takes four minutes before it goes off again.

Current status
The heat symbol allows you to see the current status of EB-Therm. See the Symbols on the display section. Symbol on – the thermostat is on and the underfloor heating is activated.
Symbol off – the thermostat is on and the underfloor heating is switched off.

Control functions
EB-Therm 205 can regulate the temperature in three different ways. This enables the comfort temperature and any flooring temperature requirements to be combined.

How you select the function you want is described in the How to set EB-Therm/ Control functions section.

Floor thermostat – A sensor in the floor measures the temperature and then regulates the heating accordingly. If the floor sensor is connected when the thermostat is turned on for the first time, this function is selected automatically. The preset value is 22 °C.

Room thermostat – EB-Therm 205 has built-in sensors for measuring the room’s temperature and controlling the heating. The control function cannot be selected when the floor sensor is connected.

Room and flobor thermostat – 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 5 °C and 45 °C. The factory setting of 35 °C gives a surface temperature of approx. 27 °C. The cut-out temperature can be changed, see the How to set EB-Therm/ Temperature section.

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 Room and floor thermostat function must always be used.
