APPLICATION
The H1008A,D Automatic Humidity Controls with
HumidiCalc+™ Software are duct mounted and provide
automatic, low voltage, electronic control of by-pass flow-
through, powered flow-through, steam and drum humidifiers
in central heating systems. The H1008D also controls heat/
energy recovery units and dehumidifiers. The H1008A,D are
designed to automatically adjust the humidity level based on
indoor temperature and humidity, inferred or measured
outdoor temperature and the setting of the frost factor dial.
The frost factor setting is used to maintain a comfortable
humidity level in the home while reducing moisture
condensation on inside windows. The HumidiCalc+™
Software infers the outdoor temperature by monitoring the
equipment cycles and eliminates the need for an outdoor
temperature sensor when used on single-stage gas or oil
furnaces. With the use of the C7089H Outdoor Temperature
Sensor (purchased separately), the H1008A,D also provide
automatic humidity control in heat pump and multi-stage
systems.
FEATURES
• The H1008A,D provides automatic control for by-pass
flow-through, powered flow-through, steam and drum
humidifiers in central heating systems.
• The H1008D also provides automatic control for
dehumidification using heat/energy recovery
ventilators or dehumidifiers.
• Patented Honeywell HumidiCalc+™ Software
eliminates the need for an outdoor sensor on the most
common single-stage, gas or oil forced air equipment.
• Combination temperature and humidity sensor
accurately determines the dewpoint at the control
location.
• Equipment connection can eliminate the need for a
current sensing relay on the blower.
• Simple duct mount requires only a 3/4 in. (19 mm)
circular duct opening for sensors.
• With the use of the C7089H Outdoor Temperature
Sensor, the H1008A,D also provides automatic
humidity control in heat pump and multi-stage
systems.
• Automatically adjusts humidity level based on the
frost factor set by the homeowner.
• Frost factor input allows for variances in furnace
oversizing, window insulation and average daily
climate temperature.
• System status light indicates normal operation, test
mode and fault indication.
