Digital Fan Coil Thermostats
PRODUCT DESCRIPTION
The SuitePRO™ is a family of Digital Fan Coil
thermostats for residential and commercial applications
such as hotels, condominiums, school classrooms, etc.
Four 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.
• 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/
cool changeover; 24Vac.
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
• 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. The Low,
Medium, High, or Auto fan settings are easily made with
a press of a key.
Valves and auxiliary electric heaters can be controlled using
a relay or contactor controlled by the system switch.
