TIS Smart Home Co, LTD and TIS Control Limited have developed the KNX TIS Module to make the integration between TIS and KNX easy. This Module converts the KNX Protocol to the TIS Smart Home Protocol and vice versa.
All TIS smart home products, such the Luna panel, lighting switches, and dimmers can control the KNX actuator for lighting, dimming, and air conditioning,
Also, a KNX panel can control TIS relays, dimmers, IR emitters, and HVAC modules for air conditioning control.
The TIS application for smart phones can also fully control KNX devices with the help of this Module.
