DEVICE DESCRIPTION

The EU-WiFi 8s controller is an online wireless device for controlling electric actuators STT-868/STT-869 ( software version 2.1.8 and later) (up to 6 actuators per zone). Its main task is to maintain constant temperature in the rooms with the use of actuators for 8 heating zones. The controller is equipped with an additional contact for switching on/off an additional device (e.g. a gas boiler).
Controller functions:

• Controlling up to 8 zones with the use of:
  – built-in temperature sensor
  – wired sensor
  – possibility of connecting 8 additional wireless sensors C-8r, C-mini or room regulators R-8b, R-8z or R-8bw (software version 2. 1. 19 and later)

• NO/NC relay output (e.g. for controlling the heating device which is activated when the room temperature is too low)

• Possibility of connecting up to 6 wireless electric actuators STT-868 or STT-869 in each zone (software version 2.1.8 and later)

• Software update via USB

• Each zone may by assigned an individual operation mode (constant temperature, time limit or 6 operation schedules)

• Compatible with C-8zr wireless external sensor

• Compatible with wireless window sensors C-2n (up to 6 sensors per zone)

Controller equipment:

• Power supply 5V
• Wired sensor C-7p

The heating system may be managed via a web application at www.emodul.eu. The eModul application may be downloaded from the Google Play store.

PRINCIPLE OF OPERATION

The EU-WiFi 8s controller decides if a given zone needs to be heated on the basis of current temperature value sent by the room sensor (C-8r, C-mini or C-7p) or the room regulator (R-8b, R-8z, R-8bw (software version 2. 1. 19 and later)), as well as the individual operation algorithm of the zone. If heating is necessary, the EU-WiFi 8s controller activates the voltage-free contact, 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 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/STT869 (version 2.1.8 and later), which require registration.

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 controller cover and connect the wires following the diagrams below and the connector labels. Keep the following order:

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 (with controller version 2.1.8 and later)
5. Configure window sensors (optional)

1. HOW TO CONFIGURE INTERNET CONNECTION
EU-WiFi 8s 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 Menu > WiFi network selection. 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 www.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).
2. HOW TO CONFIGURE EXTERNAL SENSOR
It is necessary to register the external sensor by selecting in the EU-WiFi 8s 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

• The external sensor is not involved in the control process.
• 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.

3. HOW TO CONFIGURE TEMPERATURE SENSORS AND ROOM RE GULATORS
To enable EU-WiFi 8s to control a given zone, it is necessary to provide it with current temperature value. The easiest way is to use C-8r or C-mini 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 R-8b, R-8z or R-8bw room regulator (software version 2.1.19 and  later). Regardless of the type of temperature sensor / room regulator chosen, it must be registered in a particular zone in the EU-WiFi 8s 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 C-8r, C-mini, R-8b, R-8z and R-8bw (software version 2.1.19 and later), press the button once briefly). If the process has been completed successfully, the EU-WiFi 8s controller display shows an appropriate message. Otherwise, the process must be conducted again.

NOTE
Only one room sensor may be assigned to each zone.
Zone 1 is the zone where EU-WiFi 8s is installed – its operation is based on the readings from the built-in sensor.
Zone 2 uses readings from the wired temperature sensor connected to the EU- WiFi 8s controller. The user may change the sensor type to wireless in these zones in the zone MENU (MENU -> Zones -> Zone 1 -> Type of sensor).
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 by selecting OFF in the submenu of a given zone.
– 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 www.emodul.eu
4. HOW TO CONFIGURE WIRELESS THERMOSTATIC ACTUATORS STT-868/STT-869 (SOFTWARE VERSION2.1.8 AND LATER)
The next step involves registering a given actuator in the zone.
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 EU-WiFi 8s 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. After this time EUWiFi 8s considers the registration attempt as unsuccessful.
4. If the registration process has been completed successfully, the display shows an appropriate message. In case of any errors, the display shows 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

5. HOW TO CONFIGURE WINDOW SENSORS

In order to register the window sensor, select ‘Registration’ (Main menu -> ) and press briefly 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 FUNCTIONS

BLOCK DIAGRAM – CONTROLLER MENU ZONES
This submenu enables the user to configure operation parameters for particular zones.
2.1. REGISTRATION
The Registration function is available for zones 3-8 and zones 1-2 if wireless sensor type has been selected.
Once the room sensor has been switched on and registered in a given zone, its readings are used by the EU-WiFi 8s controller. The sensor may be disabled by deselecting ON.
2.2. ON
Once the room sensor has been switched on and registered in a given zone, its readings are used by the EU-WiFi 8s controller. The sensor may be disabled by deselecting ON.
2.3. TYPE OF SENSOR
This option is available for zones 1 and 2. The user chooses the sensor type between internal sensor (built-in or wired sensor) and wireless sensor.
2.4. 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.
2.5. 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.
2.6. 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.
2.7. ACTUATORS
This submenu is used to configure the operation of thermostatic actuators STT-868 or STT-869 (controller version 2.1.8 and later). In each zone it is possible to register up to 6 actuators STT-868 or STT-869 (controller version 2.1.8 and later).
The registration process is described in detail in First start-up section. 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 display shows an information panel.
SETTINGS – FROM VERSION 2.1.34
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.
Range – parameter which specifies the room temperature at which the valve starts opening and closing.
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.

Example:
Pre-set zone temperature: 23˚C
Minimum opening: 30%
Maximum opening: 90%
Range: 5˚C
Hysteresis: 2˚
In the above example, the thermostatic valve starts closing at the temperature of 18˚C (pre-set value minus Range: 235).
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.
Protection – If the pre-set temperature is exceeded by the number of degrees specified in the parameter, all actuators in a given zone will be closed (0% opening). This function works only when the SIGMA function is enabled.
Emergency mode – This function enables the user to define the actuator opening which will be forced in the event of an alarm in a given zone (sensor failure, communication error). The emergency mode of thermoelectric actuators is enabled in the event of power loss in the EU-WiFi controller.
2.8. 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 in 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 the information 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 sends the information to the main controller. If the sensor sends another information that the window is open after 10 minutes, the main controller will force the actuators to close and disable the heating in the given zone.
NOTE
If the delay time is set at 0 minutes, the message 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 current temperature on the main screen as well as via emodul.eu application. The external sensor is not involved in the control process.

HOW TO CONTROL THE HEATING SYSTEM ONLINE

Our website www.emodul.eu offers multiple tools for controlling your heating system. In order to take full advantage of the technology, create your own account:
Registering a new account at www.emodul.eu
Once logged in, go to Settings tab and select Register module. Next, enter the code generated by the controller (to generate the code, select Registration in the EU-WiFi 8s controller menu). The module may be assigned a name (in the field labelled Module description). 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 define a separate pre-set temperature value which will apply in the zone regardless of the time.
Selecting Constant temperature it is possible to set 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 previous 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 controller:
1. Local schedule
It is a weekly schedule assigned to a particular zone. Once the EU-WiFi 8s 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 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.
