2) Status: locking (L); blocking (B)
Description Cause Remedy (by contractor)
ON A8 B No communication with
EMS heat appliance
Communication cannot be established between
the hybrid control module (internal unit) and the
boiler
Check the EMS connection between the hybrid
control module (internal unit) and the boiler.
Check the contacts, cables and connections
between the hybrid control module and the
boiler.
Replace damaged cables and contacts, replace
the appliance PCB if necessary.
ON A8 B No communication with
system controller
Check the contacts, cables and connections
between the hybrid control module and the
system controller
Repair or replace the bus cable
Check the system controller Replace the system controller if necessary
ON CC B Outside temperature
sensor faulty
Use the voltage and pressure drop values to
check the sensor
If the sensor is faulty, replace it
Check the sensor connection Reconnect the sensor in the correct way
ON d1 L Return temp. sensor
contact faulty
Temperature sensor short circuit - Condenser
inlet
Check and possibly replace contacts, wiring or
temperature sensor

contact faulty
Temperature sensor open circuit - Condenser
inlet
Check and possibly replace contacts, wiring or
temperature sensor
OFF B Flow or return
temperature outside the
permissible range
Hybrid manager flow or return temperature
outside the permissible range
Initially the boiler heats the water before the heat
pump starts.
ON E2 L Flow temperature sensor
faulty
Temperature sensor short circuit - Condenser
outlet
Check and possibly replace contacts, wiring or
temperature sensor
ON E2 L Flow temperature sensor
faulty
Temperature sensor open circuit - Condenser
outlet
Check and possibly replace contacts, wiring or
temperature sensor
ON EF L System fault appliance
PCB / basic controller
Check contact between the appliance PCB and
the mounting base along with the base controller
and the base plate, and check all other plug-in
connections
Rectify contact problem, replace appliance PCB
or boiler identification module if necessary
Hybrid system: Component fault in hybrid control
module
Check the hybrid control module and replace if
necessary
ON HP L External unit / water flow
rate fault
