About the GFX3 Digital Humidistat
In Automatic Mode the GFX3 will adjust the humidity in your home based on the outdoor temperature, lowering the humidity
in cold weather to reduce condensation. The GFX3 can operate in Manual or Automatic Mode to control humidity to a
specific relative humidity. In most homes, Automatic operation is preferred to reduce condensation on windows and within
the structure. Manual mode is necessary where the outdoor temperature sensor cannot be installed. Manual mode may be
desirable where valuable artwork, instruments or woodwork demand constant humidity. The LCD Display is backlit and easy
to read. Operation and Installation are simple.
WARNING!
Always TURN OFF POWER TO THE HVAC SYSTEM prior to installing or servicing the humidifier or humidistat. Improper
operation can result in over or under humidification. This humidistat requires a 24 volt, AC power supply. Improper voltage
can cause malfunction or damage to the control. Do not run outdoor sensor wires on or near line voltage wires. The
technical specifications for this product and the contents of the user manual are subject to change without notice.
