Malfunction
Decision Conditions
Supposed Causes
Blocked waterflow or heat exchanger (waterside).
The water circuit has a too high ESP (external static pressure).
Troubleshooting
Caution
Be sure to turn off power switch before connect or disconnect connector,
or parts damage may be occurred.
The water circuit has a too high
ESP compared to the maximum
allowed ESP (see technical
specs). Consider installing an
additional pump with higher
external static pressure in
combination with a balancing
bottle.
Make sure that:
- all valves are open
- water pressure is OK
(0,3bar<P<3bar)
- all air is out of the system
- the waterfilter is clean
YES
NO

Re-install the 3-way valves
correctly
Is
the waterflow or heat
exchanger blocked?
Is the
position of the 3-way
valves OK?
Can be checked
(see A6 error)
