DEVICE DESCRIPTION
EU-295 room regulator is intended for controlling thermoactuators. Its main task is to maintain the pre-set room temperature by sending a signal to the actuator (contact closing) when the room temperature is too low.
EU-295 regulator functions:
- Maintaining pre-set room temperature
- Manual mode
- Day/night mode
Controller equipment:
- Built-in temperature sensor
- Batteries
- Possibility of connecting a floor sensor
- Possibility of pairing with MW-1 (v2 version)
INSTALLATION
The controller should be installed by a qualified person. EU-295 controller may be installed on the wall.
The room regulator should be connected to the heating device using a two-core cable, as illustrated below: EU-295v2 
NOTE The marking on the back of the controller refers to the built-in transmitter. It does not refer to the type of actuator connected.
NOTE The regulator is powered with batteries, which should be periodically checked and replaced at least once every heating season. In order for the control circuit to operate properly, it is necessary to provide the regulator with 230 V AC power supply, as illustrated in the diagram.
FIRST START-UP
Follow these step while starting the controller for the first time to ensure proper operation:
- Remove the front cover and insert the batteries.
- Connect the regulator to the actuator as illustrated in the diagram.
HOW TO USE THE CONTROLLER
- PRINCIPLE OF OPERATI ON
The main task of ST-295 is to maintain the pre-set room/floor temperature by sending a signal to the heating device (contact closing) or to the external controller managing the actuators, when the room/floor temperature is too low. When such a signal is received, the heating device opens the flow in the thermostatic valve. - OPERATION MODES
The regulator may operate in one of the two operation modes available:
Day/night mode – in this mode the pre-set temperature changes depending on the time of the day. The user presets the temperature values for both day-time and night-time as well as the time of entering day mode and night mode. In order to activate this mode, press EXIT and hold until a corresponding icon (day/night mode) appears on the main screen.
Manual mode – In this mode, the user sets the temperature in the main screen view using PLUS and MINUS buttons. The manual mode will be activated automatically after pressing one of these buttons. Once this mode is activated, the previously selected mode enters ‘sleep mode’ and remains inactive until the next preprogrammed temperature change.
The manual mode may be deactivated by pressing EXIT button.
MAIN SCREEN DESCRIPTION
The user navigates in the menu structure using buttons.

Use PLUS and MINUS to set the hour and minute of night mode activation. Confirm by pressing MENU button (confirm and move on to edit the next parameter) or EXIT button (confirm and return to the main screen view).
- PRE-SET TEMPERATURE HYSTERESIS
Room temperature hysteresis defines the pre-set temperature tolerancein order to prevent undesired oscillation in case of small temperaturefluctuation (within the range of 0,2 ÷ 5°C).
Example:
Pre-set temperature: 23°C
Histeresis: 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 the hysteresis settings appear on the screen.
Use PLUS and MINUS to set the desired hysteresis value. Press MENU to confirm and move on to the next parameter or press EXIT to confirm and return to the main screen view. - UNDERFLOOR HEATING O N/OFF
In order to enable or disable underfloor heating, press MENU until underfloor heating settings appear on the screen.
To activate the underfloor heating, press PLUS. Confirm by pressing MENU button (confirm and move on to edit the next parameter) or EXIT button (confirm and return to the main screen view).
To deactivate the underfloor heating, press MINUS. Confirm by pressing MENU button (confirm and move on to edit the next parameter) or EXIT button (confirm and return to the main screen view). - MAXIMUM FLOOR TEMPERAT URE
In order to set the maximum floor temperature, activate the underfloor heating (section 8) and press MENU until the maximum floor temperature settings appear on the screen. Use PLUS and MINUS to set the temperature. Confirm by pressing MENU button (confirm and move on to edit the next parameter) or EXIT button (confirm and return to the main screen view).
- MINIMUM FLOOR TEMPERATURE
In order to set the minimum floor temperature, activate the underfloor heating (section 8) and press MENU until the minimum floor temperature settings appear on the screen. Use PLUS and MINUS to set the temperature. Confirm by pressing MENU button (confirm and move on to edit the next parameter) or EXIT button (confirm and return to the main screen view).
- UNDERFLOOR HEATING H YSTERESIS
Underfloor heating hysteresis defines the tolerance for the maximum and minimum temperature. The settings range is 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 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 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.

HOW TO REGISTER EU-295 V2
In order to register EU-295v2, follow these steps:
- Press Registration button in MW-1;
- Press and hold Registration button in EU-295v2 for 5 seconds.
NOTE
Once registration has been activated in MW-1, it is necessary to press the registration button in EU-295v2 controller within 2 minutes. When the time is over, the pairing attempt will fail.
If:
- EU-295v2 screen shows SCS and all the control lights in MW-1 are flashing simultaneously – the registration has been successful.
- the control lights in MW-1 are flashing one after another from one side to the other – MW-1 module has not received the signal from the main controller
- EU-295v2 screen displays ERR and all the control lights in MW-1 light up continuously – the registration attempt failed.
