Do you need to easily and efficiently control a heat pump, fan coil, or roof top unit? We have an AppStat for that. The BAC-4000 series AppStat combines a controller, multiple sensor options, and BACnet networking into a single, integrated space-mounted device. Appstat offers a unique, cost-effective combination of networking, application, and sensor options along with easy, intuitive installation, configuration, and operation.

Preloaded with factory-programmed application sequences, AppStat models support these types of equipment.

  • Fan coil units (FCU)—Options include two- or four-pipe heating/cooling, three-speed or modulating fan control, two-way on/off or modulating valves, and dehumidification.
  • Roof top units (RTU) or similar packaged or split systems—Options include single-stage, two-stage, or modulating heating and cooling, dehumidification, economizer, and fan control.
  • Heat pump units (HPU)—Options include three stages of heating and two stages of cooling with economizer and auxiliary heat, fan control, and dehumidification (requires auxiliary heat).
