TAC Erie™ Digital, 3-Wire Floating Thermostat/Controller
Model Chart
The T158 series microprocessor based
thermostat/controller with digital display provides
3-wire floating, on/off control, or a combination of
3-wire floating and on/off control. This series
controls a 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:
• Heating and cooling outputs are individually configurable
for 3-wire floating or on/off control in the normally open or
normally closed modes.
• Line voltage continuous 3-speed fan control.
• Manual or automatic changeover.
• Remote setback capability from a time clock or facility
management system.
• Time out feature. Drive signal stops after 3 mins (max) on.
• Fahrenheit or Celsius display capability.
• Built-in purge cycle assists the controller to determine if the
controlling agent is providing heating or cooling.
• Microprocessor eliminates the necessity for tuning or
calibration.
• Display can be calibrated to within ±5F degrees (2.5C
degrees).
