BOILER SERVICE REMINDER
If your house is rented, by Law, your gas boiler should be inspected once a year to
ensure it is operating safely. Your ST9120C Timer has a range of features designed
to help make sure this service is carried out at the correct time. These features will be
programmed by your Installer, Maintenance Engineer, or Landlord.
• If it has been set to do so, ST9120C will display a message on the screen to
remind you that a boiler service is due.
• If the service is overdue, the Timer may switch off the heating system, to ensure
your safety. If this happens you must arrange an immediate service visit. Contact
details should be listed on page 26 of this guide, in the section Boiler & System
Service Log.
• A contact telephone number may also have been programmed into the ST9120C.
If so, a message will appear on the LoT™ Display indicating the number you
should call.
Countdown to Service
Your ST9120C can indicate a countdown for the
number of days until your service is due. This
message will appear on the screen every few
seconds, to give you an opportunity to schedule
a service visit.
When Service is Due
When your boiler service is OVERDUE the words
“SERVICE DUE” will continue to flash on your
screen, and you should arrange an immediate
service visit.
