DESCRIPTION
This product rectifies a common problem encountered in office spaces - multiple zones supplied by one air conditioning unit via extensive ductwork, controlled by a single thermostat. With this scenario, some parts of the space get too hot, others too cold. This happens despite best efforts to balance the amount of supply air to individual zones. This is partly subjective - different people perceive the temperature differently and partly real problem of a non-uniform air flow.
This is greatly exacerbated when the office floor is repartitioned, when new tenants move in and the one thermostat ends up 'behind the wall'. The new tenant is at mercy of the people that occupy the zone with the thermostat
ZilvarTM multizone controls correct the problem by distributing the control from one thermostat to multiple (up to five) thermostat, one for each zone. These sense the zone temperature and close or open the motorized damper(s) installed in the duct(s) supplying the zone, based on the mode (heating or cooling) the air conditioning unit is in. The mode itself is determined by the state of the thermostats.
