The H1008A,D Automatic Humidity Control with
HumidiCalc+™ Software is designed to provide an optimal
50°F (10°C) dewpoint and automatically adjusts the
humidity level to prevent window frost or condensation.
The H1008D activates a ventilator or dehumidifier to lower
the indoor humidity level when the house dewpoint rises
above 58°F. Outdoor temperature is inferred (without the
need for an outdoor sensor), or measured (with optional
outdoor sensor) by the HumidiCalc+™ Software. Indoor
humidity and temperature information is measured by
sensors located on the back of the control. The frost
factor–set by using the frost factor dial–allows for variables
in furnace oversizing, window insulation and average daily
outdoor temperature. The Automatic Humidity Control with
HumidiCalc+ Software requires an initial adjustment
period. To adjust the frost factor, set the frost factor dial to
10 and use Table 1 to adjust the frost factor—only one
setting at a time—increasing the dial setting for more
humidity, or decreasing the setting if moisture starts to
build up on the inside of your windows. For more precise
humidity adjustments, set the frost factor between the dial
settings. Allow two days for the humidity level to subside
before making further adjustments. Once the frost factor
has been set, no further adjustment is needed.

ERROR STATUS

M13306A
To troubleshoot the system where error status is indicated:
— If an outdoor temperature sensor is not used:
— First check to ensure that the OUT terminals are
properly shorted together.
— Then cycle power to the device. If the control
continues to flash in the error mode, replace the
humidity control.
— If an outdoor temperature sensor is used, disconnect
it, short the OUT terminals together and cycle power.
If the error status remains, replace the humidity
control. If the error status is eliminated, replace the
outdoor temperature sensor.
Control enters the error mode if any sensor reads out-of-
range. See Table 3.
