MYNUTE X R
For fault E041
If the pressure drops below the safety threshold of 0.3 bar the boiler displays the fault code
<<E041 water transducer load the system>> for a transitional time of 30sec.
When the transitional time has finished, if the fault persists the fault code E040 is displayed.
When the boiler has fault E040 manual loading should be carried out using the filling tap (external
to the boiler) until the pressure is between 1 and 1.5 bar. Then press RESET.
Close the filling tap (external to the boiler), making sure to hear the mechanical snap. At the end
of the procedure, proceed with the automatic vent cycle as described in the section "3.15 Filling
the heating system and eliminating air".

If the drop in pressure is very frequent, contact the Technical Assistance Centre.

For fault E060
The appearance of the E060 fault, on models with water tank with probe connected,
prevents sanitary operation.
For fault E091
The boiler has an auto-diagnostic system which, based on the total number of hours in
certain operating conditions, can signal the need to clean the primary exchanger (alarm
code E091). Once the cleaning operation (made with special kit supplied as an accessory)
it is necessary to reset to zero the total hour meter following procedure indicated below:
ƒ access the technical parameters as explained in the section "3.19 Access to the
parameters"
ƒ select the CONF menu and then EXHAUST PROBE RESET with the keys
ƒ set the parameter to 1 confirming the selection with
NOTE: The meter resetting procedure should be carried out after each in-depth cleaning
of the primary exchanger or if this latter is replaced.
The total hours can be verified in the following way:
ƒ access the INFO menus as indicated in the paragraph "4.21 INFO menu" at EXHAUST
PROBE RESET to display the value of the flue gases probe meter.
