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 contactor. Optionally, it is possible to connect an additional sensor to the floor sensor contact – additional functions will appear in the controller menu.

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 the 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 the 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 the EXIT button.
• Constant mode – In this mode, the pre-set temperature will apply all the time, regardless of the time of day.

8. 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 – 1°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. Use or to set the desired hysteresis value.
9. 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, use or to enable the heating, and then use the same buttons to set the maximum temperature.
   • Minimum temperature – in order to set the minimum floor temperature, press MENU until the floor heating icon appears on the screen. Next, use 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 1 °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: 1°C
     When the floor temperature reaches 33°C, the underfloor heating will be disabled. It will be activated again when the temperature drops to 32°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.
   • Minimum floor temperature: 23°C, Hysteresis: 1°C
     When the floor temperature drops to 23°C, the underfloor heating will be enabled. It will be disabled when the temperature reaches 24°C.

• PN EN IEC 63000:2019-01 RoHS

Troubleshooting

• Temperature displayed seems inaccurate: Perform built-in sensor calibration or floor sensor calibration (if the floor sensor is enabled) in the controller menu, as described in the calibration functions.
• Underfloor heating behavior seems inconsistent near setpoints: Review and adjust HYSTERESIS. The hysteresis is used to prevent undesired oscillation; it defines the tolerance for switching behavior around pre-set temperatures.
• Noisy/oscillating switching in day/night or constant control: Adjust HYSTERESIS (range described in the manual as 0.2°C to 1°C for hysteresis-related underfloor heating settings).
• Heating does not respond to changes: Verify operation mode selection (day/night, manual, constant) in the controller menu and confirm that the controller is connected to the heating device as specified.
• Button control not working: If button lock is enabled, unlock by pressing and holding any button.
• Need to reset settings: Restore factory/default settings using the “DEFAULT SETTINGS” menu function (YES/NO).
