Maintenance of the unit
The components of the heating circuit and the heat
source (valves, expansion vessels, circulating pumps,
filters, dirt traps) should be inspected and cleaned as
necessary - however, at least once a year - by qualified
personnel (heating or cooling system fitters).
It is best to arrange a maintenance agreement with
a heating installation company. The company will
arrange the necessary regular maintenance work.
Malfunctions
In the event of a fault, you can read out the cause of
the fault from the diagnostic program of the heating
and heat pump regulator.

pump regulator.
ATTENTION
Only customer service personnel authorised
by the manufacturer may carry out service
and repair work on the components of the
unit.
Note that no malfunction is displayed if the safety
temperature limiter on the electric heating element has
tripped.
