When the UA connects to the AVV air handler or a two-stage furnace, you can configure the UA to monitor the indoor control’s float switch input.

When the float switch activates, the UA disables compressor operation for five minutes. If the float switch is still active after the five minutes, the UA continues to disable compressor operation until the float switch deactivates.

You can configure the float switch operation with the Settings > Float Switch parameter in the following way:

  • Disabled: the UA does not affect compressor operation based on float switch behavior.
  • Enabled Open: if the float switch is open, the UA suspends compressor operation for at least five minutes.
  • Enabled Close: if the float switch is closed, the UA suspends compressor operation for at least five minutes.
