The heating system may be managed via a web application at https://emodul.eu. The eModul application may be downloaded from the Google Play or Apple store.

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. for controlling the heating device, and opens the actuators registered in a given zone. The signal from each zone is transmitted to the EU-WiFi 8S p controller via room regulators or room sensors. They communicate with the controller via radio signal. Each zone may be assigned wireless valve actuators STT-868/STT-869 (registration is necessary).

HOW TO INSTALL THE CONTROLLER

The controller should be installed by a qualified person.
WARNING
**** Risk of fatal electric shock from touching live connections. Before working on the controller switch off the power supply and prevent it from being accidentally switched on.
Remove the back cover and connect the wires.

Next, connect the wires following the diagrams below and the connector labels.

Keep the following order:

• 230V supply cable to the controller connector
• additional device (e.g. a heating device)

Connection with the EU-MW-1 module:

FIRST START-UP

In order for the controller to work properly, follow these steps while starting it for the first time:

1. Configure the Internet connection

2. Configure the external sensor (optional)

3.  Configure the room sensors, room regulators

4. Configure wireless thermostatic actuators STT-868/STT-869

5. Configure window sensors (optional)

6. HOW TO CONFIGURE INTERNET CONNECTION
   EU-WiFi 8S p has a built-in Internet module, which enables the user to control the heating system via the Internet. First, connect to the Internet by selecting your WiFi network in the menu: . Such parameters as IP Address, IP Mask, Gate Address may be set manually or it is possible to activate DHCP option (enabled by default).
   Next, go to https://emodul.eu/ and create your account. After selecting in the controller menu, the system generates a code which must be entered in tab of the emodul.eu website (Register module).

7. HOW TO CONFIGURE THE EXTERNAL SENSOR EU-C-8ZR
   It is necessary to register the external sensor by selecting in the EU-WiFi 8S p controller ( Main menu > External sensor > Registration) and pressing the communication button on the external sensor (press the button briefly once).
   The registration process enables the external sensor automatically. Once registered, the sensor may be switched off at any time by selecting . **NOTE**
   Switching the sensor off in the external sensor menu only interrupts the communication (the external temperature is no longer displayed on the external controller screen). It does not disable the external sensor itself – it remains active until the battery is flat.

8. 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. Regardless of the type of temperature sensor / room regulator chosen, it must be registered in a particular zone in the EU-WiFi 8S p controller menu.
   In order to register the sensor/room regulator, go to the submenu of a given zone and select Registration (Zone/Registration). Next, press the communication button which can be found on the back of the selected temperature sensor/room regulator (in the case of EU-C-8r, EU-R-8b, EU-R-8bw, EU-R-8z, press the button once briefly). If the process has been completed successfully, the EU-WiFi 8S p controller display will show an appropriate message. Otherwise, the process must be conducted again. The following rules must be kept in mind:
   – Only one temperature sensor may be registered in each zone.
   – Once registered, the sensor cannot be unregistered, but only switched off in the submenu of a given zone (by selecting OFF).
   – If the user attempts to assign a sensor to the zone to which other sensor has already been assigned, the first sensor becomes unregistered and it is replaced by the other one.
   – If the user attempts to assign a sensor which has already been assigned to a different zone, the sensor is unregistered from the first zone and registered in the other one.
   It is possible to set individual pre-set temperature value and a weekly schedule for each room sensor assigned to a given zone. The pre-set zone temperature may be adjusted in the controller menu (Main menu / Zones). Weekly schedule settings and the pre-set values may be configured via https://emodul.eu.

9. HOW TO CONFIGURE WIRELESS THERMOSTATIC ACTUATORS STT-868/STT-869
   NOTE
   The maximum of 6 actuators may be registered in each zone.
   Registration process:
   1. Install the thermostatic actuator on the radiator and wait until it calibrates.
   2. Go to the EU-WiFi 8S p menu, select the zone number where the actuator is to be registered and select Actuators/Registration.
   3. Press the registration button on the actuator within 120 seconds from selecting Registration option. When the time is over, the registration attempt will be considered unsuccessful.
   4. If the registration process has been completed successfully, the display will show an appropriate message. In case of any errors, the display will show an appropriate message.
   There are 2 possible causes of errors in the registration process:
   – an attempt to register more than 6 actuators
   – no signal from the valve actuator within the period of 120 seconds

10. HOW TO CONFIGURE WINDOW SENSOR
    In order to register the sensor, go to EU-WiFi 8S p menu and select the number of the zone where the sensor is to be registered. Next, select Window sensors/Registration and press quickly the communication button on the window sensor.
    Release the button and watch the control light:
    • control light flashes twice – proper communication established
    • control light lights up continuously – no communication with the main controller

CONTROLLER FUNCIONS

1. BLOCK DIAGRAM – MAIN MENU

2. ZONES 1-8
   This submenu enables the user to configure operation parameters for particular zones.
   2.1. REGISTRATION
   The Registration function is available for zones 1-8.
   Once the room sensor has been switched on and registered in a zone, it will be used by the EU-WiFi 8S p controller. It may also be disabled by deselecting ON.
   2.2. ON
   Once the room sensor has been switched on and registered in a zone, it will be used by the EU-WiFi 8S p controller. It may also be disabled by deselecting ON.
   2.3. PRE-SET TEMPERATURE
   The pre-set zone temperature depends on the weekly schedule settings. However, this function enables the user to change this value separately – it is necessary to deactivate the schedule. The user may set constant temperature or for a pre-defined period of time.
   2.4. HYSTERESIS
   This function is used to define tolerance of the pre-set temperature in order to prevent undesired oscillation in case of small temperature fluctuation (within the range 0,1 ÷ 10⁰C) with the accuracy of 0,1°C.
   Example: if the pre-set temperature is 23⁰C and the hysteresis is 0,5⁰C, the zone temperature is considered too low when it drops to 22,5⁰C.
   2.5. CALIBRATION
   Room sensor calibration is performed while mounting or after it has been used for a long time, if the zone temperature displayed differs from the actual temperature. Calibration range is from -10⁰C to +10⁰C with the accuracy of 0,1⁰C.
   2.6. ACTUATORS
   This submenu is used to configure the operation of STT-868/STT-869 thermostatic actuators. It is possible to register up to 6 actuators in each zone. The registration process is described in detail in the section First start-up. In order to unregister all actuators from a given zone, select Actuator removal function.
   From 1.1.0 actuator software version on, it is possible to identify, monitor status or remove single actuators. In order to do it, press the button on the actuator and hold it for about 2 seconds until EU-WiFi 8S p display shows an information screen.
   The Settings submenu enables the user to configure the operation of thermostatic actuators. It is possible to define the maximum and minimum actuator opening – these levels of valve opening and closing will never be exceeded.
   SIGMA function allows for smooth control of the thermostatic valve. Once the function has been activated, the user may also define the minimum and maximum level of valve closing.
   Moreover, the user adjusts the Range parameter which specifies the room temperature at which the valve starts opening and closing.(a) – min. opening
   (b) – Actuator opening
   ZAD – set temperature
   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. At the temperature of 21˚C (pre-set value minus hysteresis: 23-2) the valve starts opening. The maximum opening is reached at the temperature of 18˚C.
   2.7. WINDOW SENSORS
   • Registration – In order to register the sensor, select Registration and press quickly the communication button on the window sensor. Release the button and watch the control light:
   – the control light flashes twice – proper communication established
   – the control light lights up continuously – no communication with the main controller
   • Sensor removal – this function is used to remove the sensors from a given zone.
   • Information – this option is available only when the sensor is registered. It enables the user to view all the sensors and check their range and battery level.
   • Settings – This function is used to set the delay time. When the pre-set delay time is over, the main controller sends a signal to the actuators forcing them to close. The time setting range is 0-30 minutes.
   Example: Delay time is set at 10 minutes. When the window is opened, the sensor reports it to the main controller. If the window is still open after 10 minutes, the main controller will force the actuators to close and disable heating in the given zone.
   NOTE
   If the delay time is set at 0 minutes, the signal forcing the actuators to close will be sent immediately.

3. EXTERNAL SENSOR
   It is possible to connect an external temperature sensor to the controller. The device enables the user to monitor currenttemperature 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 processis described in detail in First start-up section.
   After registering the sensor, the user may check the battery level and signal strength as well as calibrate the sensor. Theexternal sensor is not involved in the control process.

4. VOLTAGE-FREE CONTACT

Registering a new module

1. HOME TAB
   Home tab displays the main screen with tiles illustrating the current status of particular heating system devices. Tap on the tile to adjust the operation parameters: **NOTE**
   No communication message means that the communication with the temperature sensor in a given zone has been interrupted. The most common cause is the flat battery which needs replacing.
   Tap on the tile corresponding to a given zone to edit its pre-set temperature:The upper value is the current zone temperature whereas the bottom value is the pre-set temperature. The pre- set zone temperature depends by default on the weekly schedule settings. Constant temperature mode enables the user to set a separate pre-set temperature value which will apply in the zone regardless of the time.
   By selecting constant temperature icon, it is possible to set the temperature with time limits.
   This mode enables the user to set the temperature value which will apply only within a pre-defined period of time. When the period is over, again the pre- set temperature depends on the weekly schedule settings (schedule or constant temperature without time limit. Tap on Schedule icon to open up the schedule selection screen: Two types of weekly schedules are available in the EU-WiFi 8S p controller:
   1. Local schedule
   It is a weekly schedule assigned to a particular zone. Once the EU-WiFi 8S p controller detects the room sensor, the schedule is assigned automatically to the zone. It may be edited by the user.
   2. Global schedule (Schedule 1..5)
   Global schedule may be assigned to any number of zones. The changes introduced in the global schedule apply to all zones where the global schedule has been activated.
   After selecting the schedule tap on OK and move on to edit the weekly schedule settings: Editing a weekly schedule
   Editing enables the user to define two programs and select the days when the programs will be active (e.g. from Monday to Friday and the weekend). The starting point for each program is the pre-set temperature value. For each program the user may define up to 3 time periods when the temperature will be different from the pre-set value. The time periods must not overlap. Outside these time periods the pre-set temperature will apply. The accuracy of defining the time period is 15 minutes.
