TAC Erie™ Digital, Proportional Thermostat/Controller
Model Chart
The T168 series microprocessor based
thermostat/controller provides 0-10 Vdc or 4-20 mA
control. This series controls variety of two-pipe and
four-pipe fan coil units, air handling units, and
various heating and cooling applications.
The microprocessor combines a proportional plus
intergral control algorithm with advanced adaptive
logic. This provides control without the need for
tuning or calibration the control algorithm in the
field.
Features:
• 0-10 Vdc or 4-20 mA heat and cool outputs.
• Low voltage fan cycling operation with demand output.
• Remote setback capability from a time clock or facility
management system.
• Auxiliary heat function.
• Remote and/or seasonal changeover sensor optional.
• Fahrenheit or Celsius display capability.
• In two pipe mode a built-in purge cycle assists the
controller to determine if the controlling agent is providing
heating or cooling.
• Line voltage continuous on/off or 3-speed fan control.
