Honeywell TB6575A1000 Thermostat

The Honeywell TB6575A1000 is an industry-standard SuitePRO digital fan coil thermostat engineered for high-reliability performance in 2-pipe and 4-pipe fan coil applications. This line-voltage controller operates on either 120Vac or 240Vac, making it a versatile drop-in solution for commercial environments like hotels, condos, and classrooms. It features a advanced Proportional plus Integral (P+I) control algorithm for precision temperature regulation, eliminating the wide swings common in mechanical thermostats. With manual or automatic heat/cool changeover and the proprietary VersaSpeed fan ramping technology, this unit ensures optimal airflow and occupant comfort. This model is the verified direct replacement for the 33CSCNACHP-FC, T6069A4010, and T6069B4018. Built with non-volatile EEPROM memory, all installer configurations and user setpoints are permanently retained during power loss without the need for batteries.

Key Benefits for Technicians and Property Managers:

• Universal Voltage Compatibility: Supports 120Vac and 240Vac power supplies with inductive fan ratings of 6.0A and 3.0A respectively.
• Flexible System Integration: Configurable for 2-pipe or 4-pipe systems with seasonal, manual, or automatic changeover settings to match any central plant architecture.
• Advanced Fan Control: Includes 3-speed fan switching (High, Medium, Low) plus an Auto-Fan mode that resets to ensure energy-efficient operation.
• System Protection: Integrated freeze protection algorithm automatically activates heating if temperatures drop below safety thresholds.
• Simplified Installation: Comes pre-fitted with color-coded 16 AWG fly leads for rapid terminal connections and mounts directly to standard horizontal 2"x4" junction boxes.

Common Technical Questions:

Does this unit require a neutral wire?
Yes, for 120Vac applications, a neutral wire must be present at the thermostat to power the digital logic and display.

Can I use a remote sensor with the TB6575A1000?
Yes, it supports optional 20k Ohm NTC remote indoor temperature sensors and pipe sensors for seasonal changeover and automatic purge cycles.

Is this thermostat compatible with 24Vac systems?
No. The Honeywell TB6575A1000 is a line-voltage thermostat (120/240V). For 24V applications, the TB8575A1000 is the appropriate model.
