Error code on control device

Incident
System over pressure
Dry run rainwater
Dry run drinking water
Cistern backflow
Level sensor fault
Pressure sensor error
62
Cause
Despite the fact the rainwater storage tank is
filled, the level sensor has not switched pumping
mode. Cable damaged or level sensor blocked in
the rainwater storage tank
System automatically replaces the water in the re-
plenishment reservoir (see chapter 7.1)
Replenishment valve defective or mechanically
blocked
Fuse protection triggered internally (depending on
model) or externally
Error code Cause
E060 Threshold value 5.24
reached (system pressure
has exceeded the permiss-
ible rated pressure)
E062.1 No minimum pressure
reached after start-up/op-
eration of pump(s) in rain-
water mode (RWM) for a
certain time period
E062.2 No minimum pressure after
start-up/operation of the
main pump (MP) in drinking
water mode (TWM) for a
certain time period
E065 Optional sensor at cistern
backflow contact (X3:7&8)
has been triggered
E40.0 No contacting or incorrect
contacting
Short-circuit or wire break
(signal value outside the
4-20 mA range)
E40.1 Short-circuit or wire break
(signal value outside the
4-20 mA range)
Remedy
Check contacts or carry out visual inspection.
Functioning according to programme, no meas-
ures required (see chapter 6.2).
Carry out a visual inspection. If necessary, remove
the replenishment reservoir and check and adjust
the replenishment valve.
Pump with too high start current due to blockage,
check possible cause.
Self-acknow- Next steps
ledging
The system continues to work; the error is
displayed. The cause (pressure increase
due to heating or impermissible inlet pres-
sure) must be found, the system pressure
must have dropped below the value for the
switch-off pressure ("1.05") and acknow-
ledged.
If no minimum pressure is reached in the
specified period, the pump continues to
run, switches to the TWM for an adjustable
period and then back to the RWM. If the
pressure in the RWM rises above the min-
imum pressure within an adjustable period
of time, the system operates normally
again. If the pressure does not rise, the
system changes to the TWM and back
again max. five times per hour. During this
period, the pressure value flashes in the
main screen. An error is generated after
the pump has been switched off five
times.
Pump switches off, an error is generated.
Check that the suction line is not blocked
and that there is enough water in the re-
plenishment reservoir.
Pump switches off, an error is generated.
Check the rainwater storage tank for pos-
sible contamination and backflow.
Change to drinking water mode; an error is
generated.
Check polarity and contacting. Change to
automatic mode after rectifying and ac-
knowledging error.
Change to drinking water mode; an error is
generated.
Check current value; replace sensor if ne-
cessary.
Pump switches off, an error is generated.
Check current value.
