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. 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.

cooling setpoint limits using range stops.
•
EEPROM permanently retains user settings,
including setpoints, during power loss (no
batteries required).
•
Selectable °C or °F display via Setup button on
thermostat.
•
Displayable pipe sensor temperature readout to
aid in troubleshooting.
