DEVICE DESCRIPTION
EU L-8 external controller is intended for both wired and wireless control of the valves (see: Wireless communication). The
controller enables significant energy saving due to precise temperature management in particular rooms. Due to advanced
software, the controller fulfils a wide range of functions:
•
possibility of controlling up to 22 thermostatic actuators via 8 room sensors C-8r, C-mini or room regulators R-8b and
R-8z (3 room sensors may support up to 12 actuators (the maximum of 4 actuators per one sensor); 5 room sensors
may support up to 10 actuators (the maximum of 2 actuators per one sensor)
•
one 230V output for a pump
•
voltage-free contact (e.g. for controlling the heating device)
•
possibility of connecting ST-507 Internet or WiFi RS to control the system via the Internet
•
possibility of connecting M-8 wireless control panel
•
possibility of controlling the mixing valve (via ST-431N valve module or i-1m)
•
possibility of updating the software via USB
•
possibility of controlling wireless actuators STT-868 or STT-869 (6 per section)
