A CONTROL-T20 should be positioned at each switch-on of a facility using JISO Smart Control. This device allows the facility’s functions to be expanded to include those mentioned previously and, therefore, enable control via VOICE or remote access. In this case, a CONTROL-T20 must be installed per circuit to be controlled, with this acting as the master and linking the circuit’s controllers (Control-V10, Control-V20, Control-C10, Control-S10) as slaves. It is easily set up via clicks; the type of function to be used must be set up before pairing.
