II. Description of the device
L-6 external controller is intended for both wired and wireless control of the valves. It
allows the user to limit considerably the power consumption due to precise control of the
room temperature. Thanks to advanced software, the device offers a wide range of
functions:
control of the mixing valve
control of up to 18 thermostatic valves via 6 room regulators (wired connection)
o 3 room regulators may support 12 actuators (the maximum of 4 actuators per one
regulator)
o 3 room regulators may support up to 6 actuators (the maximum of 2 actuators per
one regulator)
possibility of controlling thermostatic valves via radio signal
one 230V pump output
supporting pump with speed control (via PWM signal)
voltage-free contact
possibility of connecting ST-65 GSM module allowing the user to control some of
the functions via a mobile phone.
possibility of connecting ST-500 Ethernet module allowing the user to control some
of the functions and view certain parameters via the Internet
possibility of connecting an external control panel with RS communication
