GFX4 HUMIDISTAT

See GFX4 installation manual for complete instructions. Press
to select OFF, AUTO (if outdoor sensor is connected) or
MANUAL mode.
OFF mode: The humidifier is turned off.
AUTO mode:
The GFX4 will automatically raise the humidity as the outdoor
temperature increases to provide the highest possible
humidity. The GFX4 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
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.
MANUAL mode:
The GFX4 will automatically maintain the selected humidity.
You can set your desired humidity level by pressing
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.
