Stores are cooled during the night.
Does collector circuit
pump run during the
night?
no yes
Check the controller
functions
Collector temperature is
at night higher than
ambient temperature.
no yes
Check the return flow
preventer in feed flow
and return flow with
regard to the functional
efficiency.
Is store insulation
sufficient?
yes no
Intensify the insulation.
Is store insulation close
enough to the store?
yes no
Replace or intensify the
insulation.
Are the store
connections insulated?
yes no
Insulate connections.
Warm water outflow
upwards?
no yes
Change connection and
let the water flow
sidewards or through a
siphon (bow downwards);
less store losses now?
Does warm water
circulation run for a
very long time?
no yes
Use the circulation pump
with timer and switch-off
thermostat (energy
efficient circulation)
The solar circuit pump does not work although the
collector is obviously warmer than the store.
Does the control LED
flash?
yes no
Does the pump start up
in manual operation?
yes
There is no current;
check fuses / replace
them and check power
supply.
The adjusted temperature
difference for starting the
pump is too high; choose
a value which makes more
sense.
no
Is the current of the
pump released by the
controller?
yes
Is the pump stuck?
Put the pump into
operation by means of a
screwdriver; is it passable
now ?
Is the pump defective -
replace it.
Are the fuses of the
controller o.k.?
Controller seems to be
defective - replace it.
no
yes
no
no yes
Replace the fuses.
Switch-off the circulation
pump and the blocking
valve for 1 night; less
store losses?
yes no
Check the pumps of the
after-heating circuit
according to nightly run
and defect return flow
preventer; problem
solved?
no
no yes
o.k.
Control the return flow
preventer in warm water
circulation- o.k.
yes no
Please also check further
pumps which are
connected to the solar
store.
The gravitation circulation
in the circulation line is
too strong; insert a
stronger return flow pre-
venter or an electrical 2-
way valve behind the
circulation pump; the 2-
way valve is open in
pump operation, other-
wise it is closed, conect
Cleaning or
replacement.
pump and 2-way valve in
parallel; activate the
circulation again!
