The microprocessor controller is factory programmed, wired, and tested prior to shipment. The controller can operate stand-alone or integrated with a Building Management System (BMS) using BACnet MS/TP or IP, or Modbus RTU or IP protocols. This controller is responsible for operating the unit in a safe and energy efficient manner.

End-users no longer need physical access to the unit mounted microprocessor to adjust control point parameters. The optional remote interface displays and allows control point parameters to be adjusted. The remote interface is available as an accessory to the microprocessor or network interface.

Greenheck's microprocessor controller comes standard with a web user interface allowing the unit to be viewed and controlled from a web browser. With an Ethernet connection from the RV, RVE, or RVC unit to the facilities network, a full graphic, specific to the unit selected, will allow for monitoring and control of the unit without a building management system (BMS). Other features include full control display access, customizable data trending, and service contact information.
