CHECK THE HUMIDIFIER OPERATION
Set the knob to Test/Reset, make sure that the water
saddle valve is open and that there is electricity to
the humidifier. The HVAC fan must be running for
the humidifier to function. NOTE: Turning the knob
to Test/Reset resets the Change Water Panel timer.
The humidifier will only operate for 1 minute in test
mode. (Model 400 and 400M: Floats must be down
for the solenoid valve to allow water flow.) Reduce the
humidifier control setting to the recommended indoor
humidity, depending on the outside temperature.
DO NOT LEAVE IN TEST MODE AS HUMIDIFIER WILL NOT
OPERATE.
NOTE: If the control knob is left in the Test/Reset
position, after 1 minute the display will show the
software revision level (r1, r2, r3, etc.) and the blue
backlight will flash.

ADDITIONAL INFORMATION
Your humidifier is a precision system that will
accurately maintain the humidity in your home. For
every 2°F change in outdoor temperature, the Digital
Humidifier Control will automatically adjust the indoor
RH by 1%.
The Digital Humidifier Control will accurately control the
humidity in your home to a maximum of 45%.
The humidity values in TABLE 2 are targets based on
outdoor temperature and the Digital Humidifier Control
setting. The actual humidity may vary due to conditions
in the home (cooking, showering, etc.).
