294KIT
The Smart Boiler Control 294KIT provides central and indirect domestic hot water heating or volume domestic hot water heating by operating up to four boilers. This can be expanded in groups of four boilers through the use of expansion controls up to a maximum of sixteen boilers. The Smart Boiler Control 294 operates both condensing and non-condensing boilers that are either modulating, single, two, three or four-stage to provide a flexible, cost-effective hybrid boiler plant solution. The Nexa(TM) by Watts web and mobile applications provide real-time remote monitoring, setting adjustments, and notifications. The 294KIT comes with wireless mesh indoor and outdoor sensors and mesh network extenders to set up a mesh network for advanced indoor feedback.
