OFF mode: The humidifier is turned off.
MANUAL mode: The GFX3 will work to maintain the single humidity selected. You can set
your desired humidity level by pressing or . The humidifier will turn ON or OFF
according to your manual setting. (The humidifier will operate when the measured relative
humidity falls more than 2% below the set point.) Humidity will have to be lowered when
weather is colder or if condensation is suspected.
AUTO mode: The GFX3 will automatically raise the humidity as the outdoor temperature
increases. This provides the highest possible humidity. The GFX3 will automatically lower the humidity as temperatures drop. This
minimizes the risk of condensation on cold surfaces like windows. You can adjust the Auto Humidity Index Set Point from 0 (low) to
10 (high) by pressing or . The Humidity Index is based on the outdoor temperature and indoor humidity. The humidifier will
switch ON/OFF according to the calculated auto humidity index set point. Lower Index settings are for older homes with less
insulation and vapor barriers. Higher Index settings are for newer homes with complete vapor barriers, triple pane windows and high
R value insulation. If condensation occurs reduce Index setting by 2 points until condensation stops.
NOTE If the outdoor temperature sensor fails, flashes and the unit will default to MANUAL mode.
