    SAFETY Before using the device for the first time the user should read the following regulations carefully. Not obeying the rules included in this manual may lead to personal injuries or controller damage. The user’s manual should be stored in a safe place for further reference.

  • Page 5: Device Description

    III. PRINCIPLE OF OPERATION The EU-WiFi 8S p controller decides if a given zone needs to be heated on the basis of current temperature value sent by the room sensor or the room regulator, as well as the individual operation algorithm of the zone. If heating is necessary, the controller activates the voltage-free contact (or sends a signal via EU-MW-1) which may be used e.g.

    HOW TO CONFIGURE TEMPERATURE SENSORS AND R OOM REGULATORS To enable EU-WiFi 8S p to control a given zone, it is necessary to provide it with current temperature value. The easiest way is to use the EU-C-8r temperature sensor. If the user wants to be able to change the pre-set temperature value directly from the zone, it is advisable to use EU-R-8b , EU-R-8bw or EU-R-8z room regulator.

    Example: Pre-set zone temperature: 23˚C Minimum opening: 30% Maximum opening: 90% Range: 5˚C Hysteresis: 2˚C In the above example, the thermostatic valve starts closing at the temperature of 18˚C (pre-set value minus Range: 23-5). The minimum opening is reached when the zone temperature reaches the pre-set value. After reaching the pre-set value, the temperature starts falling.

    It is possible to connect an external temperature sensor to the controller. The device enables the user to monitor current temperature on the main screen as well as via https://emodul.eu. Once the external sensor has been installed, it must be registered in the EU-WiFi 8S p controller – the registration process is described in detail in First start-up section.
