OPERATING LIMITS
If the temperature in the space to be conditioned drops below 40°F or rises
above 99°F, the control will not allow the humidifier to operate. Under these
conditions, the display will blink “ON” and “
*
.” Once the temperature is in the
normal operating range, the control will once again allow the humidifier to
operate and the blinking “ON” and “
*
” will no longer be displayed.
ADJUSTING THE RH DISPLAY OFFSET
If you have another device that displays RH in your home, it may not match the
Model 65 control display due to placement or a difference in calibration. If you
want the devices to match, the RH displayed by the Model 65 control can be
adjusted higher or lower by up to five percentage points. Allow the control to
acclimate to the space for 48 hours before adjusting the offset.
The control must be on in order to adjust the offset. Press and hold the “OFF”
button for 5 seconds or until the display shows a value between -5% and +5%.
Use the
and buttons to adjust the offset. The control will revert back to
the normal display mode after 5 seconds.
OPERATING INSTRUCTIONS – MODEL 63 AUTOMATIC
DIGITAL MODULATING CONTROL
The Aprilaire® Model 63 Automatic Digital Modulating
Control (ADMC) offers precise control of the humidity in
your home by providing a variable output based on the
difference between the set point and the sensed humidity.
The Automatic Digital Modulating Control offers 2 modes
of operation, Automatic or Manual. An explanation of both
modes follows. When in 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 ADMC automatically adjusts your home’s humidity based on the outdoor
temperature, increasing the time maximum comfort is maintained.
• Simple operation with few adjustments. In the Automatic Mode, the ADMC
eliminates the need to manually adjust the control when outdoor temperature
changes.
