Honeywell #TB6575A1000, 3-Speed Fan Coil Thermostat; 2 or 4 pipe Manual/Auto changeover, Heat/Cool/Auto, 3 speed fan; Supply voltage: 120/240 Vac

Honeywell #TB6575A1000, 3-Speed Fan Coil Thermostat; 2 or 4 pipe Manual/Auto changeover, Heat/Cool/Auto, 3 speed fan; Supply voltage: 120/240 Vac

The TB6575A, TB6575B, and TB8575A are a family of Digital Fan-Coil thermostats for residential and commercial applications. They are great for use in hotels, condos, and school classrooms. They provide line voltage and low voltage on/off control for various fan-coil units. The three models provide control of 2 or 4 pipe fan-coil units, 120, 240, or 24 Vac, and manual or automatic heat/cool changeover. The fan can also be controlled from the thermostat, which offers three fan speeds (Low, Med, High) and Auto. Valves and auxiliary electric heaters can be controlled using a relay or contactor system switch controlled by the thermostat.

Features
Simple, intuitive user interface and ease of installation.
Attractive modern styling ideal for hotels and condos.
Digital display of ambient temperature, setpoint, mode icons when cooling or heating relays operate, when energy savings mode is active, and fan status
Four buttons allow manual control of system operation, fan speed, and temperature setpoint adjustment.
VersaSpeed Fan Ramp Algorithm automatically adjusts Low, Medium, High fan speed.
Optional freeze protection feature that turns on heat, if necessary.
Activity sensing algorithm sets back thermostat to economy mode.
Auto fan rest option sets back fan to auto mode.
Energy savings mode- external energy savings input from dry contact such as time switch, occupancy sensor, or hotel cardkey overrides comfort setpoint with selectable setback heating or cooling setpoints.
Energy savings input configurable as a normally open or normally closed dry contact.
Proportional plus integral (P+I) control algorithm for precision temperature regulation.
Selectable C or F.
Adjustable deadband, in auto changeover mode, for heat and cool control.
Adjustable maximum heating and minimum cooling setpoint limits.
Installer setup mode allows changes of operating parameters.
EEPROM permanently retains user settings, including setpoints, during power loss (no batteries required).
Capability to display temperature sensor failure for easier troubleshooting.
Optional remote temperature sensor and remote pipe sensor.
