II. SYSTEM DESCRIPTION
The EU-L-4X WiFi board is designed to control the heating device and supports 4 zones. It also supports wireless and wired
RS-485 (TECH SBUS) communication. Due to the additional EU-ML-4X module, WiFi allows expansion of the installation by an
additional 4 zones. Its primary function is to maintain the preset temperature in each zone. EU-L-4X WiFi is a device that,
together with all peripheral devices (room sensors, room regulators, floor sensors, external sensor, window sensors,
thermostatic actuators), forms the entire, integrated system.
Because of its extensive software, the EU-L-4X WiFi control board can:
•
support up to 4 dedicated wired EU-R-12b, EU-R-12s, EU-F-12b, EU-R-X controllers and the wired EU-C-7p sensor
•
operate several different wireless controllers, e.g. EU-R-8X, EU-R-8b, EU-R-8b Plus, EU-R-8s Plus, EU-F-8z and sensors:
EU-C-8r, EU-C-mini, EU-CL-mini
•
support EU-C-8f floor temperature sensors
•
support EU-C-8zr external sensor and weather controls
•
support wireless EU-C-2n window sensors (up to 6 pcs per zone)
•
allow control of STT-868, STT-869 or EU-G-X wireless actuators (6 pcs per zone)
•
allow operation of thermostatic actuators
•
allow operation of the mixing valve – after connecting the EU-i-1, EU-i-1m valve module
•
control the heating or cooling device by means of a voltage-free contact
•
allow one 230V output to the pump
•
provide possibility to set an individual operation schedule for every zone
•
allow updating the software via USB port
Updates of the list of devices for expanding the system are provided on an ongoing basis on our website
The controller has a built-in Internet module, enabling the user to remotely control the system via the https://emodul.eu
website or through the emodul application.
III. INSTALLING THE CONTROLLER
The EU-L-4X WiFi control board should only be installed by a properly qualified person!
WARNING
Danger of injury or death due to electric shock on live connections. Before working on the controller, disconnect
