The TB7600 Series PI thermostat is available in BACnet® MS/TP and ZigBee® and integrates into a WEBs-AX automation. It features a menu-driven, back-lit LCD display, up to three sensor inputs, an auxiliary output, and one or two digital inputs.


  • Available in BACnet MS/TP and ZigBee wireless protocols
  • Built in default profile set-up for easier start up and commissioning
  • Fully integrated advanced occupancy functionality with a PIR accessory cover on some models
  • Programmable smart fan operation
  • Password protection to minimize parameter tampering
  • Three levels of keypad lockout
  • Gas/oil or electric system compatibility for all type of applications
  • SPST auxiliary output can be used for lighting and/or economizer override
  • 0 to 10 Vdc economizer output for more retrofit opportunities
  • Automatic frost protection to prevents costly freeze damage
  • Anti short cycle and minimum on/off run time protection to reduce wear and maximizes life span of mechanical equipment
  • One or two programmable digital inputs for added flexibility can be use to monitor filter status, activate a remote temporary occupancy switch, and/or used as a general purpose service indicator
  • Heat Pump models support single and two stages heat pump with one auxiliary heat stage, selectable single or dual stage compressor stages, and comfort/economy mode maximizes heat pump use before turning on auxiliary heating, compressor/auxiliary interlock adds flexibility by locking out heat pump operation during auxiliary heating to prevent high pressure trip when the coil is downstream of the auxiliary heat source
  • 7 day programmable models, 2 or 4 events for use in non-networked applications.
