Operating phase:
The flow temperature sensor has detected
that the current flow temperature is higher
than the flow temperature setting on the
BC10, or that it is higher than the flow
temperature. Calculated according to
heating requirements, or that it is higher
than the flow temperature calculated for the
DHW mode.
e
Fault:
The flow temperature sensor has measured
a current flow temperature higher than
95 °C.
e
Fault:
The safety temperature sensor has
measured a current safety temperature
higher than 95 °C.
e
Fault:
The return temperature sensor has
measured a current return temperature
higher than 95 °C.
e
Fault:
There is no connection between contacts 78
and 50 of the UBA 3 installation base.
e
Fault:
The system pressure is too low (less than
0.2 bar).
e
Fault:
The flow temperature sensor has not, after
burner start-up, detected any temperature
increase in the heating system water.
e
Fault:
The heating water temperature difference,
measured between the flow temperature
sensor and the safety temperature sensor, is
too high.
