TYPE OF DIAGNOSTIC PROCEDURE
FULL DIAGNOSTIC MODEL
Tests all aspects of appliance operation from start to finish.
FAULT / INFORMATION CODES
Using LEDs 3 and 4 on the PCB, this will carry out tests relevant to the fault code chosen.
LITE DIAGNOSTIC
Allows you to jump to a section of the full diagnostic model - this will bypass some parts of the full diagnostic model which could cause misdiagnosis.
QUICK ACCESS - DATA / INFORMATION
Provides access to an appliance data table and how to obtain the readings in it - by choosing this option you will bypass the full model which could cause misdiagnosis.
POOR COMBUSTION INVESTIGATION
This option will investigate likely causes if the appliance is heating the
system correctly but has failed a flue gas analyser test.
This does not replace TOPs A1 interim & servicing policies.
Ensure all relevant safety checks are carried out.
