Your humidifier is controlled by either an Automatic Digital
Humidifier Control, or a Manual Humidifier Control.
The Automatic Digital Humidifier Control offers two modes of
operation, Automatic or Manual. When in the Automatic Mode,
this system offers the following benefits:
•
You will receive the optimum amount of humidity so that
your home and its furnishings are protected from the
damaging effects of excess condensation or low
humidity during the heating season.
The Control
automatically adjusts your home’s RH based on the outdoor
temperature, increasing the time maximum comfort is
maintained
•
Simple operation with few adjustments.
The Control
eliminates the need to manually adjust the control when
outdoor temperature changes. It also eliminates the need to turn
the dial setting to “OFF” during the summer season.

OPERATING INSTRUCTIONS
Blower Activation
Digital Humidifier Control Indicator Lights
Set the “Blower Activation Switch” to “ON” to allow the
humidifier control to activate the HVAC fan for maximum
humidification. For this setting the Models 500, 600 and 700 must
be connected to hot water.
If the HVAC system has been idle for one hour, the humidifier
control will activate the HVAC system fan to sample the air for 3
minutes. If the RH is lower than the set point, the humidifier
control will activate the humidifier and keep the fan running. The
humidifier will continue to operate for 2 hours or until the
humidification set point is reached.
If the RH set point has not been reached by the end of a call for
heat, the control will continue to operate the humidifier and the
HVAC fan until the humidification set point is reached or 2 hours
have elapsed.
When the “Blower Activation Switch” is in the “OFF“ position, the
humidifier control will only operate the humidifier if humidity is
required and the HVAC system fan is operating or the HVAC
system is producing heat.
NOTE:
If used in conjunction with an Aprilaire 8570
Communicating Thermostat, and the blower activation feature is
desired, DO NOT wire the A B communication terminals.
