No – The control unit does not make any service calls.
Yes – The control unit makes services calls as programmed by the options described below.
2 – Call Number
Use this option to select one of the 8 telephone numbers programmed using Option 2-5-1-4.
This will be the telephone number that the control unit calls when starting a service call.
3 – Time Period
On the day that a service call is due, there may be times when it is inconvenient for the control
unit to call, or for the service centre to receive calls. Use this option to define a time window. If
the control unit needs to make repeated attempts to complete a service call, then these
attempts all take place with this time window. The start and end times of the window must be
on the same day.
When you select this option the screen immediately displays the Start Time. Key in the start time
in hours and minutes. Use the 24 hour clock. Press [ to finish.
The screen then displays the End Time. Key in the end time in hours and minutes. The end time
must be later than the start time. Use the 24 hour clock. Press [ to finish.
4 – Next Service
Use this option to specify the day and time of the next service call. To prevent all control units
making service calls at the same time, make sure each control unit has a different date and/or
time.
When you select this option the screen immediately displays the Service time. Key in the
preferred time of day for the service call. Use the 24 hour clock. Press [ to finish.
The screen then displays the Service Date. Key in the preferred date for the service call. Press [
to finish.
Note: The control unit may change this date if it has to make several attempts to connect to
Downloader.
5 – Interval
Set the time period between service calls in days. You can select the frequency of service calls
from between one a day to one every 365 days.
When you select this command the screen shows the current value of the Interval in days.
Key in the number of days you require. Use leading zeroes for day numbers under 100. (You can
also press | or ¬ to increase or decrease the number of days one at a time.) Press [ to finish.
6 – Call Back
There are two methods of connecting a service call from the control unit: either “direct in” or
“call-back”.
For a “direct-in” call, the control unit simply dials the specified number, identifies itself to the
service centre, and then waits for commands from the Downloader.
