2-Pipe and 4-Pipe Fan Coil Applications
The TB8575A1000 supports multiple fan coil configurations including:
- 2-pipe heat only
- 2-pipe cool only
- 2-pipe heat/cool with manual changeover
- 2-pipe heat/cool with seasonal changeover
- 2-pipe systems with auxiliary heat
- 4-pipe heat/cool with manual changeover
- 4-pipe heat/cool with automatic changeover
Three-Speed Fan Control
The Honeywell SuitePRO thermostat provides High, Medium and Low fan-speed control along with Auto and Off settings.
Its VersaSpeed fan-ramp algorithm automatically adjusts fan speed as needed to help maintain room temperature.
Energy-Saving Features
The TB8575A1000 includes several configurable energy-management functions, including:
- External energy-saving input
- Occupancy sensor compatibility
- Hotel card-key setback capability
- Activity-based setback
- Auto fan reset
- Adjustable heating and cooling setpoint limits
- Optional freeze protection
- EEPROM memory that retains settings during power loss
Is the TB8575A1000 Programmable?
No. The TB8575A1000 is a non-programmable digital fan coil thermostat. It does, however, include configurable energy-saving and setback functions.
What Voltage Is the TB8575A1000?
The TB8575A1000 operates on 20–30 VAC, with 24 VAC being the nominal supply voltage.
What Is the Difference Between TB8575A1000 and TB6575 Models?
The TB8575A1000 is the low-voltage 24 VAC SuitePRO model.
The TB6575 family includes line-voltage versions designed for 120V, 240V or 277V applications. They should not be treated as interchangeable without confirming the fan coil system's electrical requirements.
Optional Accessory
Honeywell / Resideo 50033847-001 adapter plate can be used when mounting the thermostat vertically to compatible 2" x 4" or 4" x 4" junction boxes.
