II. DEVICE DESCRIPTION
The EU-WiFi 8s mini controller
actuators per zone). Its main task is to maintain stable 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 all parameters via a web application https://emodul.eu

Controlling up to 8 zones with the use of:
- possibility of connecting 8 wireless sensors C-8r, C-mini or room regulators R-8b, R-8bw, R-8z.

NO/NC relay output (e.g. for controlling the heating device which is activated when the room temperature is too
low)

Possibility of connecting in each zone:
- up to 6 wireless electric actuators STT-868/STT-869
- up to 6 wireless window sensors C-2n

Software update via USB port

Each zone may by assigned an individual operation mode (constant temperature, time limit or 6 operation
schedules)

Compatible with wireless external sensor C-8zr

Compatible with wireless repeater RP-4

Possibility of connecting an executive module MW-1
Controller equipment:

Built-in internet module

5V in-wall power supply

Wireless temperature sensor C-mini
The heating system may be managed via a web application at www.emodul.eu. The eModul application may be
downloaded from the Google Play or Apple store.
III. PRINCIPLE OF OPERATION
The EU-WiFi 8s mini 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 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 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).
