thermostats for residential and commercial applications
such as hotels, condominiums, school classrooms, etc.
Four models are available for your application:
• TB6575A1000:

automatic heat/cool changeover; 120/240 Vac.
• TB6575B1000: 2-pipe only with seasonal or manual
heat/cool changeover; 120/240 Vac.
•
TB6575C1000: 2-pipe or 4-pipe with seasonal/manual/
automatic
heat/cool changeover; 120/240/277 Vac.
• TB8575A1000: 2-pipe or 4-pipe with seasonal heat/

All four models are suitable for multiple applications.
Changes in output wiring and external links between
wiring terminals allow you to configure the thermostat for
the appropriate application.
The applications that are available are:
• Heating or Cooling only
