Device description

The EU-T-3.1 room regulator is intended for controlling the heating device.
Its main task is to maintain the pre-set flat/floor temperature by sending a signal to the heating device (contact closing) or the main controller which controls the actuators, when the room/floor temperature is below the preset value.
The EU-T-3.1 regulator functions:

• Maintaining pre-set room temperature
• Manual mode
• Day/night mode
• Control of the floor sensor Controller equipment:
• Touch buttons
• Front panel made of glass
• Built-in temperature sensor
• Batteries
  There are 2 color versions: white or black.

How to install the controller

The device should be installed by a qualified person.
In order to mount the regulator on the wall, screw the rear cover onto the wall, insert batteries and slide the device into the cover.

The EU-T-3.1 room regulator – connection diagram
The room regulator should be connected to the heating device via a two core cable. When connecting devices with over 1A load, it is necessary to use a contractor.Optionally, it is possible to connect an additional sensor to the floor sensor contact – additional functions will appear in the controller menu.

NOTE
The regulator is powered with batteries – it is recommended to check the batteries from time to time and replace them at least once every heating season.
First start-up
In order for the EU-T-3.1 controller to work properly, it is necessary to follow these steps when starting the device for the first time:

1. Insert the batteries – in order to to do it, remove the front cover of the controller.
2. Connect the controller to the heating device.
3. If the room regulator will be used to operate the floor heating system, connect an additional sensor to the floor sensor connector.

Operation modes

The room regulator may operate in one of the following operation modes:

• Day/night mode – In this mode the pre-set temperature value depends on the current time of the day. The user may set different temperature values for the daytime and nighttime as well as define the exact time of entering day mode and night mode.
  In order to activate this mode, press MENU button until one of the mode icons appears on the main screen. The user may define the pre- set temperature and (after tapping on MENU again) the time of entering day and night mode.

• Manual mode – In this mode, the pre-set temperature is adjusted manually from the main screen view with the use of these buttons
  . Manual mode is activated after pressing MENU button. Once the manual mode has been activated, the previous operation mode enters ‘’sleep mode’’ until the next pre-programmed temperature change. Manual mode may be deactivated by pressing EXIT button.

Controller functions

The user navigates in the menu structure using touch buttons: EXIT, and MENU. In order to edit particular parameters, press MENU.
By pressing MENU the user may preview the controller functions. The edited parameter is flashing. Use the buttons to change the parameter settings. Press MENU to confirm the changes and move on to edit the next parameter.

1. CLOCK – In order to set the time, press MENU button until a digital clock settings appear at the top of the screen. The settings concern the flashing parameter. Use or
   to set the hour. Next, press MENU to move to the next parameter – minutes.

2. PRE-SET DAY TEMPERATURE – In order to define the pre-set day temperature, press MENU button until a flashing icon appears on the screen. Use or to set the day temperature.

3. DAY FROM… – This function enables the user to define the exact time of entering the day mode. To configure this parameter, press MENU until a flashing icon appears on the screen.Use or to set the time of day mode activation.

4. PRE-SET NIGHT TEMPERATURE – In order to define the pre-set night temperature, press MENU button until a flashing icon appears on the screen.Use or to set the night temperature.

5. NIGHT FROM… – This function enables the user to define the exact time of entering the night mode. To configure this parameter, press MENU until a flashing icon appears on the screen.Use or to set the time of night mode activation.

6. HYSTERESIS – Room temperature hysteresis defines the pre-set temperature tolerance in order to prevent undesired oscillation in case of small temperature fluctuation (within the range of 0,2 – 5°C). Example: Pre-set temperature : 23°C, Hysteresis: 1°C The room regulator reports that the temperature is too low when the room temperature drops to 22 °C. In order to set the hysteresis, press MENU until a flashing icon appears on the screen. or to set the desired hysteresis value.

7. FLOOR HEATING ON/OFF – This function is used to enable (ON) or disable (OFF) the underfloor heating, with the use of .When the underfloor heating is enabled (icon ) the user may configure the following parameters:
   • Maximum temperature – in order to set the maximum floor temperature, press MENU until the floor heating icon appears on the screen. Next, or to enable the heating, and then use the same buttons to set the maximum temperature.
   • Minimum temperatur e – in order to set the minimum floor temperature, press MENU until the floor heating icon appears on the screen. Next, or to enable the heating, and then use the same buttons to set the minimum temperature.
   • Hysteresis – underfloor heating hysteresis defines the tolerance for the maximum and minimum temperature. The settings range is from 0,2°C to 5 °C.
   If the floor temperature exceeds the maximum temperature, the underfloor heating will be disabled. It will be enabled only after the temperature has dropped below the maximum floor temperature minus the hysteresis value.
   Example:
   Maximum floor temperature: 33°C, Hysteresis: 2°C When the floor temperature reaches 33°C, the underfloor heating will be disabled. It will be activated again when the temperature drops to 31°C. If the floor temperature drops below the minimum temperature, the underfloor heating will be enabled. It will be disabled after the floor temperature has reached the minimum value plus the hysteresis value Example:
   Minimum floor temperature: 23°C, Hysteresis: 2°C When the floor temperature drops to 23°C, the underfloor heating will be enabled. It will be disabled when the temperature reaches 25°C.

8. BUTTON LOCK ON/OFF – It is possible to activate button lock. In order to do it, press the MENU button until the icon , appears on the screen and select ON. In order to unlock the buttons, press and hold any button.

Menu button functions

By holding the MENU button the user may enter particular functions in the Menu.

1. COOLING/HEATING – This icon informs about the room heating or cooling to reach the pre-set temperature. These messages are displayed alternately: cooling or heating.

2. BUILT-IN SENSOR CALIBRATION – Calibration should be performed while mounting or after it has been used for a long time, if the room temperature measured by the sensor differs from the actual temperature. Calibration setting range is from -9,9 to +9,9 ⁰C with the accuracy of 0,1⁰C.
   To calibrate the built-in sensor, press the MENU button until the temperature sensor calibration screen appears. Use the buttons or to set the desired correction. To confirm, press the MENU button (confirm and go on to edit the next parameter).

3. FLOOR SENSOR CALIBRATION – Floor sensor calibration (an additional icon is displayed: ) should be performed if the floor temperature measured by the sensor differs from the actual temperature.
   To calibrate the built-in sensor, press the MENU button until the floor sensor calibration screen appears. Use the buttons or to set the desired correction. To confirm, press the MENU button (confirm and go on to edit the next parameter).

4. SOFTWARE VERSION – After pressing the MENU button the user may check the software version number. The number is necessary while contacting the service staff.

5. DEFAULT SETTINGS – This function is used to restore factory settings. In order to do it, change the flashing digit 0 to 1.
