Description of the thermostat

The EK760 thermostat is designed to provide comfort and energy savings, and is easily installed on thermostatic radiator valves. It regulates the ambient temperature and works in association with a home automation controller, such as TKP100A and/or with radio transmitters in the TRMxxx range, allowing you to benefi t from the associated functions of programming, check and visualization.

It allows the heating device to regulate according to 3 temperature levels:

• Comfort : The desired temperature when you are present within the room.
• Night setpoint : The desired temperature during short absences or at night.
• Frost Protection : The minimum temperature ensured during extended periods of absence. It protects your house from the risk of frost.

Installation and replacement of batteries

Remove the cover of the battery box by pressing the cover upwards at the marked location (1) and picking it up (2).

Then, place the batteries in the direction indicated at the base of the product.

Changing the batteries has no infl uence on the confi guration of the product.

Never use new and old batteries together;
nor should batteries of different brands be used together.
Do not use rechargeable batteries!
Respect the correct polarity!

Initial configuration

Once the batteries are fi tted, you can select the language used on the EK760 (English, French, German, Italian). The default language used is English, however you can change this selection by pressing on the " + " / " - " keys briefl y, then confi rm the selected language by pressing and holding on the "OK" key.

Installation

After the batteries are inserted, the motor is completely pushed upwards in order to facilitate installation. The screen will display INST (INST may also be selected from the menu, at all times). Ensure installation only in this position. Do not press the other keys, and the thermostat is ready to be fi tted.

Withdraw the head of the original thermostatic valve (caution: only the thermostatic valves can be controlled by the EK760 thermostat). The installation process is to be carried out without contact with dirt or water as the valve body remains in place.

The EK760 is fully compatible with existing thermostatic valves using M30x1.5 threading (Honeywell, Landis & Gyr, TA, Heimeier, etc.) using the white coupling ring provided.

In case of Danfoss valves, it is necessary to use an adapter provided in addition to the white ring (please refer to the correspondence table below).

Heimeier, Junkers Landys + Gyr, MNG, Honeywell, Braukmann measured thread: M30x1,5	No adapter needed
Danfoss RAV (The pin joint must be attached to the valve tappet)
Danfoss RA
Danfoss RAVL

Before installing the adapters, fully remove the protection pins marked in grey on the drawing.

If the model of the valve is different from those listed above, you must use an optional adapter listed below:

• EK771 for COMAP M28x1.5 valve
• EK772 for Oventrop M30x1.0 valve
• EK773 for Vaillant valve
• EK774 for Herz M28x1.5 valve
• EK775 for Giacomini valve

Press and hold on the "OK" key until INST disappears so that EK760 can start its installation process. The device adapts to the operating range of the valve. In some cases, this procedure may take several minutes. Once the adaptation is completed, the EK760 goes back to the normal operating mode.

• If a new adaptation is necessary (for example if your radiator does not cool down while in summer mode), select INSTALLATION from the menu until adaptation starts.
• If error ERR2 appears on the screen, fi t the EK760 on the radiator valve and then briefly remove the batteries to reinitialize.

Removal

To remove EK760, set the device in INST position (Please refer to the above chapter), wait for a brief moment and then press on the release lock located in the groove in the lower part with the fork tool delivered to disconnect.

Subsequently, remove EK760 from the valve body.

Radio Link configuration

The next step is to confi gure the radio link of EK760, to do so there are 2 options:

1. Using a house automation controller such as TKP100A, place TKP100A in product append mode, and cfg will appear on the EK760 screen and RF confi guration will be displayed subsequently. Press and hold on "OK" to start the link process. At the end of the process, it is carried out correctly if the display indicates "OK", on the other hand the operation must be repeated if it indicates "NOK" (For more information, see instructions for TKP100A).
2. Using micromodules of type TRM69x or TRM702A, place the micromodule in confi guration mode, and cfg will appear on the EK760 display screen subsequently. Press and hold on "OK" to start the link process. You can select the desired function by navigating with the "+" / " - " key then confi rming the function selected by pressing and holding on the "OK" key.
