W8735D TELEPHONE ACCESS MODULE
The contractor telephone number setting is designed to
enable HVAC contractor to provide a monitoring service at the
homeowner's request. If a telephone number is programmed
into the contractor telephone number, the W8735D also
dials-out the contractor number and continues until the HVAC
contractor acknowledges the alert.
NOTE: The W8735D considers the main and backup tele-
phone number settings independently from the con-
tractor telephone number setting. Even when the
recipient at the main or backup telephone number
setting acknowledges the alert, the W8735D dials
out and attempts to receive an acknowledgement
from the contractor telephone number, and visa-
versa.
NOTE: When the homeowner dials in and is informed that
an alert is active, the alert can be acknowledged
immediately to stop the calls to the main and backup
telephone number settings. However, the dial-out
call to the contractor number continues until an
acknowledgment is received from the contractor
number.
IMPORTANT
Only the HVAC contractor can acknowledge the alert
dialed to the contractor telephone number setting.

Contractor Access and Pass Code
The HVAC contractor dials-in to listen to or cancel the active
alert messages for the contractor telephone number setting as
follows:
1. Call the Home.
2. Enter the last five digits of the contractor's telephone
number (as entered in the W8735D) as the pass code
(e.g. if the telephone number setting is 555-6789, enter
5 6 7 8 9 as the pass code).
3. Follow the voice menu prompts to clear the active
alerts. This pass code gives the contractor access to the
alert history list only in order to acknowledge the active
alerts.
NOTE: This pass code does not clear the alert dial-out to the
main or backup numbers. It only allows the contrac-
tor access to acknowledge the alert(s). All active
alerts require independent acknowledgement by the
homeowner.
Sending Messages
Alert messages can be sent on high or low indoor/outdoor
temperature, high or low humidity, low battery, auxiliary input
sensor tripped, pass code change, air filter change required,
system failure, and power outage.
