Humidex
24
Vacant Homes
Performance results are maximized when the building is occupied. If home is vacant for a prolonged
period, then the unit should be set to operate at low speed.
Maintaining your HCS
The HCS Products do not require any internal maintenance. The only maintenance needed for your
HCS is a periodic vacuuming of the dust accumulation at the intake grilles or louvers located at the
bottom of the unit. For proper functionality do not store anything within a radius of 4 feet around the
base of the Humidex.
What is the dew point?
The dew point is one of the three important variables when discussing the conditions in your home.
Understanding the dew point will help you understand how the HCS unit operates and how it will
help to reduce the relative humidity (RH%) level infiltrating your home and reduce excess humidity,
while providing energy efficient ventilation for your home. The dew point is defined as the
temperature at which the water vapor contained in a given volume of air will condense into water.
This is best illustrated by an example:
Assume the following measurements are taken by the unit:
Temperature = 68⁰F
Relative Humidity = 60%
Using the temperature and RH% values measured, the unit would calculate that the dew point in your
home is 54⁰F. As the temperature of surfaces in your dwelling (these tend to reflect the floor
temperature, which is generally cooler than the ceiling air temperature) approaches the value of the
dew point, you risk having condensation on those colder surfaces (as well as un-insulated water pipes).
This condensation can lead to problem situations that might produce unhealthy living conditions in
your home (odors, molds, etc.)
New Installations in the Summer
Moisture has saturated in the structure over the years, more so when there was inadequate ventilation
and humidity control. Basement and crawl spaces are generally colder and damper which results in
high relative humidity. The Humidex ventilation will over time extract moisture, and lower relative
humidity by raising temperature and extracting moisture. The results and timeframe will vary for each
depending on conditions. If installed in the summertime the surfaces and structure may still be cold
and saturated, which may cause some condensation, until conditions have improved. It may require
some heat or a dehumidifier to operate for a temporary period of time to be able to raise the
temperature and lower relative humidity.
If an air conditioner is present in the house, close all AC vents/leads/ducts to the basement.
