Honeywell BACnet Integration Manual for TB7600 Series Thermostats TB7600 Series Thermostat with Occupancy Sensor TB7600 Series Thermostat REFERENCE MANUAL PRODUCT OVERVIEW The TB7600 PI thermostat family is specifically designed for single stage and multi stage control of heating cooling equipment such as rooftop and self contained units The TB7600 Series are communicating thermostats with models available in BACnet MS TP and ZigBee wireless mesh protocols and can be easily integrated into a WEBs AX building automation system based on the NiagaraAx platform The product features an intuitive menu driven back lit LCD display which walks users through the programming steps making the process extremely simple Accurate temperature control is achieved due to the product s PI time proportional control algorithm which virtually eliminates temperature offset associated with traditional differential based thermostats The TB7600 thermostats are also compatible with the Honeywell PIR occupancy sensor covers Thermostats equipped with a PIR cover provide advanced active occupancy logic which will automatically switch occupancy levels from Occupied to Unoccupied as required by local activity being present or not This advanced occupancy functionality provides advantageous energy savings during occupied hours without sacrificing occupant comfort All thermostats can be ordered with or without a factory installed PIR cover Mo
