TB6575/TB8575 SuitePRO™
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 with seasonal or manual heat/cool
changeover; 120/240 Vac.
• TB6575C1000 – 2-pipe or 4-pipe with seasonal/manual/
automatic heat/cool changeover; 277 Vac.
• TB8575A1000 – 2-pipe or 4-pipe with manual and
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.
Valves and auxiliary electric heaters can be controlled using a
relay or contactor controlled by the system switch.
FEATURES
• Simple, intuitive user interface.
• Pre-installed lead wires for fast installation (TB6575A,
TB6575B and TB6575C models only)
• Backlight display permits easy viewing in any light.
• Four buttons allow manual control of system
operation, fan speed, and temperature setpoint
adjustment.
• Digital display of ambient temperature, setpoint,
heating or cooling mode, fan status, and remote
setback
• Proportional plus Integral (P+I) control algorithm for
precision temperature regulation.
• Adjustable deadband for auto changeover using the
Heat and Cool setpoint settings.
• Adjustable maximum heating and minimum cooling
setpoint limits using range stops.
• Installer setup mode allows changes of operating
parameters.
• EEPROM permanently retains user settings, including
setpoints, during power loss (no batteries required).
• Selectable °C or °F display via Installer Setup.
• Displayable pipe sensor temperature readout to aid in
troubleshooting.
• Automatic pipe purge of five minutes once every 24
hours to ensure unrestricted flow (only when used with
optional pipe sensor).
• Fan motor always begins on high speed to ensure
sufficient torque at startup.
• Option to wire a remote indoor temperature sensor.
• Freeze protect algorithm turns on heat when needed.
• Energy Saving Options:
• Activity Sensing sets back thermostat to
economy mode when there is no activity with
the thermostat (4, 12, or 24 hours selectable).
• Remote Setback Inputs receive dry contact
input from a time switch, occupancy sensor, or
hotel card key to set back thermostat to
economy mode.
• Auto Fan Reset eliminates the fan from being
run all the time by automatically setting the fan
to auto (2 or 4 hour selectable).
• VersaSpeed™ fan ramp algorithm automatically
adjusts fan speed (low, medium, and high).
