TB6575/TB8575 Digital Fan Coil Thermostats PRODUCT DESCRIPTION The TB6575 and TB8575 are a family of Digital Fan Coil thermostats for residential and commercial applications such as hotels, condominiums, school classrooms, etc. Three models are available for your application: • TB6575A1000 - 2-pipe or 4-pipe with seasonal/ manual/automatic heat/cool changeover; 120/240 Vac. • TB6575B1000 - 2-pipe only with seasonal or manual heat/cool changeover; 120/240 Vac. • TB8575A1000 - 2-pipe or 4-pipe with seasonal heat/ cool changeover; 24Vac. All three 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 • Two pipes: Heat or Cool with Manual Changeover • Two pipes: Heat or Cool with Seasonal Changeover (requires optional pipe sensor) • Two pipes: Heat or Cool with Auxiliary Heat and Manual or Seasonal Changeover (requires optional pipe sensor) • Four pipes: Mixed Manual and Auto Changeover • Four pipes: Manual Changeover • Four pipes: Auto Changeover The fan is controlled from the thermostat.
