Description
Circuit B flow sensor fault
Circuit C flow sensor fault
Remarks:
The circuit pump is running.
The 3-way valve motor on the circuit
is no longer powered and can be
adjusted manually.
Outside temperature sensor fault
Remarks:
The boiler operates on BOILER
MAX temperature.
The valve setting is no longer ensured
but monitoring the maximum
temperature of the circuit after the
valve is ensured.
Valves may be manually operated.
Reheating the domestic hot water
remains ensured.
Auxiliary sensor fault
Domestic hot water sensor fault
Remarks:
Heating of domestic hot water is no
longer ensured.
The load pump operates.
The load temperature of the dhw tank
is the same as the boiler.
B room temperature sensor fault
C room temperature sensor fault
Note:
The circuit concerned operates
without any influence from the room
sensor.
