Description
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.
