• Page 3: I. Safety Before using the device for the first time, the user should read the regulations carefully. Not obeying the rules may lead to personal injuries or controller damage. The user’s manual should be stored in a safe place for further reference. Every person using the device should familiarize themselves with the principle of operation and security functions of the controller. If the device is sold or moved, ensure the user’s manual is included for access to essential information. The manufacturer does not accept responsibility for injuries or damage resulting from negligence; users must take necessary safety measures. High voltage warning: ensure the regulator is disconnected from the mains before any activities involving the power supply. The device should be installed by a qualified electrician and should not be operated by children. The device may be damaged if struck by lightning; disconnect the plug during storms. Any use other than specified by the manufacturer is forbidden. Care for the natural environment is a priority; dispose of used elements and electronic equipment safely.
• Page 4: Device description The 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 when the room temperature is too low. EU-295 regulator functions include maintaining pre-set room temperature, manual mode, and day/night mode. Controller equipment consists of a built-in temperature sensor, batteries, the possibility of connecting a floor sensor, and the possibility of pairing with MW-1 (v2 version). Installation The controller should be installed by a qualified person. The EU-295 controller may be installed on the wall.
• Page 5: The room regulator should be connected to the heating device using a two-core cable.
• Page 6: The marking on the back of the controller refers to the built-in transmitter. It does not refer to the type of actuator connected. 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. Follow these steps 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.
• Page 7: How to use the controller Principle of operation The main task of ST-295 is to maintain the pre-set room/floor temperature by sending a signal to the heating device or to the external controller managing the actuators when the room/floor temperature is too low. 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. 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. The manual mode may be deactivated by pressing the EXIT button. Main screen description The user navigates in the menu structure using buttons.
• Page 8: Display EXIT - pressing this button in the main screen view activates day/night mode. After entering the menu, this button is used to confirm the settings and return to the main screen view. MINUS button – pressing this button in the main screen view activates manual mode and decreases the pre-set temperature. After entering the menu, this button is used to adjust parameters. PLUS button – pressing this button in the main screen view activates manual mode and increases the pre-set temperature. After entering the menu, this button is used to adjust parameters. MENU button – hold this button in order to enter the controller menu. While editing parameters press this button to confirm the changes and move on to edit the next parameter. Press and hold MENU button for 2 seconds to see the floor temperature displayed on the screen. Press MENU button again to check the battery level. Press the button again to check the software version. Current temperature Floor heating active Current time Night mode active Day mode active Manual mode active Heating to pre-set temperature active
• Page 9: Controller functions allow navigation through the menu structure using touch buttons. To edit a parameter, press the MENU button. The icon of the edited parameter will flash while the remaining icons are blank. Use PLUS and MINUS buttons to change settings. Confirm changes by pressing the MENU button or EXIT button. The main menu includes clock settings, pre-set day temperature, pre-set night temperature, hysteresis, and underfloor heating options. To set the time, enter the menu and press the MENU button until clock settings appear. Use PLUS and MINUS to set the hour and minutes. Confirm the time setting by pressing the MENU button or EXIT button.
• Page 10: Pre-set day temperature To define the pre-set day temperature, enter the menu and press the MENU button until the pre-set day temperature settings appear on the screen. Day from… This function enables the user to define the exact time of entering the day mode. Pre-set night temperature To define the pre-set night temperature, enter the menu and press the MENU button until the pre-set night temperature settings appear on the screen. Night from… This function enables the user to define the exact time of entering the night mode. Pre-set temperature hysteresis Room temperature hysteresis defines the pre-set temperature tolerance in order to prevent undesired oscillation in case of small temperature fluctuation.
• Page 11: 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. 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. To deactivate the underfloor heating, press MINUS. In order to set the maximum floor temperature, activate the underfloor heating and press MENU until the maximum floor temperature settings appear on the screen. In order to set the minimum floor temperature, activate the underfloor heating and press MENU until the minimum floor temperature settings appear on the screen.
• Page 12: 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. 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. When the floor temperature drops to 23 °C, the underfloor heating will be enabled. It will be disabled when the temperature reaches 25 °C. Specification values include a range of room temperature setting from 5 °C to 35 °C. The supply voltage is 230V AC / 0.5A (AC1) and 24V DC / 0.5A (DC1). The operating temperature range is from 5 °C to 50 °C. The accuracy of room temperature measurement is +/- 0.5 °C. The frequency for EU-295v2 is 868MHz.
• Page 13: 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. Once registration has been activated in MW-1, it is necessary to press the registration button in EU-295v2 controller within 2 minutes. If EU-295v2 screen shows SCS and all the control lights in MW-1 are flashing simultaneously - the registration has been successful. If 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. If EU-295v2 screen displays ERR and all the control lights in MW-1 light up continuously - the registration attempt failed.
