Unreliable Sensor Operation describes how you want the coil to behave when the controlling temperature sensor is unreliable.
  • Off sends a 0% command to the coil and stops a coil pump (if you have one).

  • Hold maintains the last command to the valve.

  • Protect Coil Based on Outdoor Air Temperature opens the valve, as needed, when the outdoor air falls below the low limit setpoint. This strategy protects the air handler coils during extreme temperatures.

  • User Defined Position commands the valve to a pre-defined position while the controlling temperature sensor is unreliable.
