This function aids the performance of legally-required
emissions testing.

function button switches on the lighting and display. Pres-
sing the button again starts the chimney sweeper function
– Fig. 9. With MESplus control, the boiler temperature is
regulated to approx. 70 °C for 45 min.

other operating phases, pressing the chimney sweep func-
tion button causes an information message to be displayed

counted down (10 min.); the function or display remains un-

ting.
The chimney sweep function ends
– if the Cancel button or chimney sweep function button
is pressed – Fig. 11.
