It is possible to automatically set a minimum 'antifreeze' temperature in periods of non-use, deactivate the temperature control when opening the windows and switch centrally summer / winter settings. In the case of direct expansion (split) air conditioning systems that do not have controls or signals suitable for centralized management in the terminal block, the system will be managed by modules that have an infrared transmitter with high emission power. Thanks to a patented technology, the PICnet modules are able to fully reproduce the commands from the remote control, not just replicating predefined set points, thus guaranteeing full remote control of the unit, through centralized supervision. Throughout its history Sinthesi has developed PICnet integrations with the most popular brands and models of air conditioning systems, such as Daikin, Fujitsu, LG, Mitsubishi, GREE, Panasonic, Sharp, Toshiba and many others.
