Honeywell TB8575A1000 SuitePro Fan Coil Thermostat - 120/240 V - 2/4 Pipe. The SuitePRO is a family of Digital Fan Coil thermostats for residential and commercial applications such as hotels, condominiums, school classrooms, etc. TB6575A1000 - 2-pipe or 4-pipe with seasonal heat/cool changeover; 120/240 VAC. Suitable for multiple applications. Changes in output wiring and external links between wiring terminals allow you to configure the thermostat for the appropriate application. The applications that are available are: - Heating or Cooling only - Two pipes: Heat or Cool with Manual Changeover - Two pipes: Heat or Cool with Seasonal Changeover (requires optional pipe sensor) - Two pipes: Heat or Cool with Auxiliary Heat and Manual or Seasonal Changeover (requires optional pipe sensor) - Four pipes: Mixed Manual and Auto Changeover - Four pipes: Manual Changeover - Four pipes: Auto Changeover 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.
