W8710A EQUIPMENT MONITORING SYSTEM
18. The circuit board red LED alarm light shines steadily. If it
blinks on and off:
a. The W8710A computer and Handheld Programmer
are communicating with each other (when keys are
pressed or data sent back and forth).
b. It has detected a fault condition.
19. Start the HVAC system in the appropriate mode (cool or
heat). Press the D/T key (upper right key on the Hand-
held Programmer) to view the temperature difference
between the return and supply air as it rises in heat or
falls in cool.
HEAT D/T 40
CALC D/T 55
NOTE: If gas heat and HEAT D/T rises above 80°F (27°C),
either increase the blower one speed higher or
increase the CALC D/T using the Quick Heat Cali-
bration by pressing the 6 key, then the no.4 key and
then the Up key until the desired D/T is reached.
20. Connect a phone line from the RJ11 phone jack on the
W8710A circuit board to any convenient phone jack.
IMPORTANT
The next step must be performed to allow the
W8710A to dial out to the central station.
21. Manually send your first alert report to be sure the
W8710A is transmitting correctly (verify that the modem
and phone line are working) and to register the W8710A
with the Honeywell Central Station. To do this:
a. Make sure the house telephone is not in use.
b. Press the CLEAR button (a small yellow pushbutton
above the power slide switch and white header strip
on the circuit board) for about ten seconds until the
red LED blinks once, shines for five seconds and
then goes out.
c. Listen carefully to hear the modem clicking and
starting to dial out.
d. After one to two minutes:
(1) If the light comes back on, shining steadily, the
report was sent successfully and your office
should receive a manually Initiated fax report in
approximately three minutes.
(2) If the light comes back on, blinking, the W8710A
did not connect to the central station (busy exter-
nal phone line).Try to send the report again by
pressing the Clear button (indicator light quits
blinking when pressed).
(3) If the light blinks once, but does not go out, the
house telephone is in use or the contractor code
no. is 0, or the telephone line is faulty. To correct
the problem, see the Troubleshooting section.
22. Unplug the handheld programmer and fasten the cover
on the W8710A.
Programming Your Telephone Prefix Number
Occasionally a phone system requires a prefix number dialed
to access an outside line. One- or two- digit prefix numbers
can be stored in the W8710A:
1. Plug the handheld programmer into the W8710A.
2. Press 9.
3. Press 1 to change the phone prefix.
68-0256
4. Press Yes or No to change phone prefix (NN means no
prefix numbers are required).
5. Press 1 or 2 to select the number of digits in the prefix
number. Press 3 if no prefix number (for example, if
your prefix no. is 9, press 1).
6. Enter the first digit of the prefix number and press Enter.
7. If you pressed 2 (digits) in step 3, you will be asked to
enter the second digit of the prefix number and then
press Enter.
8. Press Yes to accept the phone prefix number (the
example shows number 9 was entered as the prefix
number. The N after 9 indicates no 2nd digit number.)
Entering Custom Setup
The setup values entered at the factory usually do not need
customizing. If necessary, adjust values as follows:
1. Press Set Up.
2. The first screen displays the Heat D/T tolerance.
(The example shows the standard factory setting for gas heat.
If another type of heat is programmed, the standard tolerance
is Electric +/- 12° or Heat Pump +/- 10°.) To change the
tolerance, press UP or DN. When the desired tolerance
setting is reached, press Enter.
NOTE: Tolerance is the number of degrees the operating
temperature split (D/T) can vary (+/-) from the cali-
brated D/T before sending an alert report.
3. The next screen displays the Cool D/T tolerance.
All standard factory settings for the Cool tolerance are
+/-6° for all types of heating systems. To change the toler-
ance setting, press UP or DN. When the desired tolerance
is reached, press Enter.
