The neoStat is a 230v powered timer with a changeover contact, making it ideal for standard and mid position valve systems. The neoStat-hw communicates to the neoHub and other neoStats within your home, to create a fully controllable network system of your home heating. Simple installation is key with Neo. neoStat has been designed to replace an existing three wire thermostat, and after joining the zone to the neoHub, remote control is possible.
