 "summary": "The SureFlow 8636 holds a room at a pressure setpoint by modulating supply and exhaust dampers, with supply flow tracking, temperature control through a reheat valve and occupied/unoccupied flow and temperature setpoints. Over BACnet MS/TP it exposes room pressure, supply flow, temperature, damper and valve positions, all setpoints and alarm limits, occupancy and emergency commands, and a Status Index alarm code.",
