We see the BAScontrol series used in commercial HVAC applications all of the time, but not so often in home automation. This Heat Pump w/ Woodstove Preheat home automation application uses the rugged BAScontrol22 for control and a Niagara JACE for supervision over BACnet/IP.
Thanks to its unrestricted, unlicensed nature, free software tools, easy Sedona block programming, BACnet/IP compliance, and web based configuration, the BAScontrol gives control power to the people!
This savvy home owner who obviously has some experience with automation has a 1800 sq ft home with attached 4000 sq ft shop. The home has a York heat pump with a 2-stage electric auxillary furnace. The shop has a wood-burning stove. An old thermostat was replaced with a BAScontrol22 and a wired wall setter for occupancy and set point adjustment.
A sheet metal heat shield with an air intake, in-line fan and insulated duct was added to the shop woodstove to allow warm air to be injected into the return air of the heat pump. The shop fan is interlocked with the heat pump supply fan.
Occupancy is controlled by either a local toggle switch on the wall setter or a schedule in the BAScontrol22. BACnet points are monitored by a JACE controller over direct connection to BACnet/IP to allow for graphical display, trend data, and alarm routing.
Web access of the BAScontrol22 allows for a greater level of temperature monitoring, control, and efficiency.
