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.

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
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

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.
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

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).
to change the 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

• Hysteresis - underfloor heating hysteresis defines the tolerance for
the maximum and minimum temperature. The settings range is from
0,2°C to 5 °C.
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

after the floor
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
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.
