If pump manufacturer requires an external main switch, power supply fuse or additional residual current device selective for distorted currents it is recommended not to connect pumps directly to pump control outputs. To avoid damaging to the device, an additional safety circuit must be used between the regulator and the pump. The manufacturer recommends the ZP-01 pump adapter, which must be purchased separately.
• Page 7: User manual Connection diagram In the case of wireless connection, use the above diagrams - a two-core communication cable should be connected to appropriate ports in the receiver. Receiver The EU-T-4.2N regulator communicates with the heating device by means of a radio signal sent to the EU-MW-3 receiver. Such a receiver is connected to the heating device by means of a two-core cable and communicates with the room regulator using a radio signal. The receiver has three control lights: Red control light 1 – it signals data reception. Red control light 2 – indicates receiver operation. Red control light 3 – goes on when the room temperature fails to reach the pre-set value; the heating device is switched on.
• Page 8: In case of no communication, the receiver automatically disables the heating device after 15 minutes. To register the EU-MW-3 receiver, press the registration button and select the Reg function in the Menu of the regulator. The message Scs indicates successful registration, while Err signifies a registration error. The number of registered relays is displayed on the screen, and if the maximum number is reached, you can choose to unregister them. To start the regulator for the first time, insert the batteries and connect the two-core cable to the appropriate sockets. The EU-T-4.1N/EU-T-4.2N room regulator maintains the pre-set room temperature by sending a signal to the heating device. The room regulator may operate in day/night mode, allowing different temperature settings for daytime and nighttime. Users can define the exact time for entering day mode and night mode. To activate day/night mode, press one of the buttons until the day/night mode icon appears on the main screen.
• Page 9: Weekly control allows users to define the timing for comfort and economical temperatures. Users can set 9 different programs divided into three groups: Programs 1-3 for daily settings, Programs 4-6 for weekdays and weekends, and Programs 7-9 for individual daily settings. The current weekly control program is displayed, showing hours for comfort and economical temperatures. To activate weekly control, press a button until the icon appears on the main screen. Manual mode allows for manual temperature adjustment using plus/minus buttons. Manual mode is activated automatically when a button is pressed and enters sleep mode until the next temperature change. Manual mode can be deactivated by pressing one of the buttons. In Day/night mode, pressing the plus/minus button activates manual mode. The controller returns to Day/night mode when daytime changes to nighttime or vice versa.
• Page 10: Example 2 - manual mode activation in weekly control mode When weekly control mode is active, the user changes the pre-set temperature by pressing plus/minus button (+ -), which automatically activates manual mode. The controller returns to weekly control mode when, according to the weekly schedule, daytime changes into nighttime or when the user presses one of the buttons.
