WATER PANEL CHANGE INDICATOR (MODEL 60 ONLY)
The control keeps track of humidifier operation time. The yellow
“Change Water Panel” light flashes after a preset amount of
running time has elapsed. This running time is preset by the
installer based on the humidifier model and water hardness.
Refer to the Annual Maintenance section for instructions on
changing the Water Panel or call your heating and air
conditioning dealer for service. After the Water Panel is
replaced, turn the Control knob to the “Test/Reset” position until
the green “Humidifier ON” light flashes, to reset the Water Panel
change timer.
TEST/RESET
The Test/Reset feature allows the humidifier operation to be
checked even if there is no call for humidity. See “Check the
Humidifier Operation” on page 12.
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.).
