Erie T158 Series Digital, Three-Wire Floating/On-Off Thermostat/Controller:
Most models of the T158 series microprocessor based thermostat/controller with digital display provide a combination of three-wire floating and/or on/off control. TA158 models are on/off control only. This series can control a variety of two-pipe and four-pipe fan coil units, air handling units, unitary equipment, for heating and cooling applications.
The microprocessor combines a proportional intergral control algorithm with adaptive logic. This provides control without the need for tuning or calibrating the control algorithm in the field.
Series Features:
- Heating and cooling outputs are individually configurable for three-wire floating or on/off control in the normally open or normally closed modes* Line voltage continuous three-speed fan control* Manual or automatic changeover* Remote setback capability from a time clock or facility management system* 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* Set point may be calibrated to +/-5F degrees
TB-158-3 Features:
- Outputs: Single* Control Signal Options: 5. Three-wire floating single stage cooling or single stage heating. 7. On/off single stage cooling or on/off single stage heating. * Fan Control: Off-Hi-Med-Lo* Remote Sensor: Yes* Setback: Yes* System Switches: Off-Heat/Off-Cool
