W8710A OPERATION
What The W8710A Does For You
How the W8710A Works
• Your W8710A automatically checks your heating and
air conditioning system every time it cycles on.
• Air sensors constantly send detailed information
about airflow, temperature and relative humidity to
the W8710A computer.
• Your W8710A then compares the information it
receives with the standards set for your home.
• Your W8710A checks and rechecks your system
thousands of times during the year to determine that
deteriorating operation is:
—
Starting to waste your energy dollars.
— Jeopardizing your heating and cooling equip-
ment.
— reducing your comfort.
How the W8710A Helps You Maintain Your Home
• Each month, a report is sent to your service
company to verify that the W8710A and your system
are working correctly.
• When the W8710A calculates that your system is
running at less than peak efficiency, its built-in
modem quickly transmits a diagnostic report to your
heating and cooling company service manager for
review.
• A service call can be scheduled before the problem
becomes an emergency. (Some problems are as
simple as the report reminder of a dirty air filter and
that it is time to clean or replace the filter.)
How the W8710A Works With Your Telephone
• W8710A detects when your phone line is in use:
—
When in use, waits until the line is clear before
transmitting an alert report.
• W8710A connects to the central monitoring stations
to quickly send its alert report information:
—
When transmitting report, total time phone line
is busy is less than one minute.
• Your service company receives you report within four
minutes of the W8710A detecting a heating or
cooling problem (if your phone line is not busy!).
• If you pick up the phone while the W8710A is
sending out a report, you may briefly hear a clicking
noise as its modem is calling the toll-free 800
number to the central monitoring station.
