This in-depth guide will show you how to program the AIRTAP register booster fan, featuring cooling and heating triggers that enhances airflow to improve your home comfort. When programming your fan, it's important to note that the temperature setting is the activation temperature. That is, it is NOT the temperature you want your room to be; it triggers based on the airflow temperature coming through your vents. The register vent booster fan does not adjust according to your comfort level, nor does it adjust your central AC or heater’s setting. Here is a rundown of how the AIRTAP works:

1. Your AC/heater is on your preferred temperature setting.
2. Air blows through your duct, by the fan's probe, and out your register.
3. The probe reads the airflow temperature, activating the fan when a trigger is tripped.
4. The register booster fan exhausts air from your duct to enhance AC/heater output.
5. It will turn off when the probe detects a higher temperature than the cooling trigger (lower temp. than the heating trigger).

We recommend establishing the two triggers one at a time to avoid confusion. When both triggers are active, the vent booster fan can be activated by airflow in temperatures not meant for your intended trigger. For example, 67°F may turn on the fan via cooling trigger when you are just turning on your heater.

To disable the trigger you are not using, hold the mode button until the display reads “OF”. If you are using your air conditioner, turn off the heating trigger; if using your heater, turn off the cooling trigger.

How to Program the AIRTAP Register Booster Fan

Follow these steps to calibrate your AC vent booster cooling trigger (skip to heater):

1. Turn on your air conditioner.
2. Set it to a temperature you regularly use.
3. Let it run for a few minutes to let the AIRTAP read a consistent temperature.
4. Press the mode button to navigate to the cooling trigger (snowflake symbol).
5. Set the cooling trigger at or above the stabilized temperature indicated by the temperature display mode.

To calibrate the air vent booster fan's heating trigger:

1. Turn on your heater.
2. Set it to a temperature you regularly use.
3. Let it run for a few minutes to let the AIRTAP read a consistent temperature.
4. Press the mode button to navigate to the heating trigger (fire symbol).
5. Set the heating trigger at or below the stabilized temperature indicated by the temperature display mode.
