Fault A60
Theboilerisworkingnormally,butdoesnotprovideanystabilityofthedomestic
hotwatertemperaturethat,inanyevent,issuppliedatatemperatureofaround
50°C. The intervention of the Technical Assistance Centre is required.
Fault A91
The boiler has a self-diagnosis system that signals the need to clean the primary
heat exchanger on the basis of the total number of hours in certain operating
conditions (alarm code A91).
Fault A91 occurs when the counter exceeds the value of 2500 hours; this value
can be checked in the “4.3 INFO menu ”,itemI015(visualization/100,
example 2500h = 25)
Aftercleaning(usingthespecialkitsuppliedasanaccessory),resetthetotal
hours counter by bringing parameter 312 = 1.
NOTE: The meter resetting procedure should be carried out after each in-dep-
th cleaning of the primary exchanger or if this latter is replaced.
