Cause
Deaeration function in progress
Communication with Dominus is offline
The board detects an anomaly on the D.H.W. recirculation
probe
Domestic hot water production is not met within the
pre-established time (see parameter P014)
The anti-Legionella cycle is run without success within the
pre-established time (see parameter P013)
The board detects an anomaly on the liquid phase NTC
probe.
A signal notifies that the outdoor unit is in test mode.
A request is made with the outdoor temperature exceeding
the operating limits (Parag. 1.16)
If communication between the printed circuit boards is
lost, an anomaly is signalled.
Too low temperature is detected in the liquid phase
An excessively high temperature is detected on the heat
pump flow circuit
An incorrect communication board configuration has
been detected
