Troubleshooting
Troubleshooting AQUATOP LOGON WP
Malfunction Cause Remedy, Action
106: Source temperature too
low B-W HP
Brine output temperatures too low (parameter
2816, -5°C)
A1 Low volume flow
A2 Geothermal heating system badly charged
A3 Geothermal heating system comp. not in order
A4 Slider closed
A5 Pump not running A1 Check pump output
A2 Vent
geothermal heating system
A3 Set flow control
A4 Open slider
A5 Check thermo relays, phases and relays
106: Source temperature too
low W-W HP
While the HP is running and the groundwater
return temperature at thermostat, built in
downstream of HP, is less than 3°C
(parameter 2815, corresponding setting 3°C),
switching to frost protection.
A
Frost protection thermostat incorrectly set
or defective.
B
Groundwater volume flow too low.
The module switches the respective unit to
the safety state when a malfunction or error
occurs.
A
Check frost protection thermostat for function
or not properly set, replace if needed.
B With too low groundwater output
temperatures, the system cannot be operated.
Min. water temperatures were not determined.
B1 Check filter for dirt
B2 Check evaporator for dirt
B3 With existing intermediate circuit, check function
of intermediate circuit, check plate exchanger
for dirt
B4 Check flow switch setting (triggers too late)
B5 Check water level in well and check its
dropping
during operation.
107: Hot gas compressor (B 81) A Too little coolant
B Compressor leak
A Top off coolant
B Replace compressor
The cooling technician must be called in these cases.
222: HP at HP operation, high
pressure
malfunction
High pressure compressor
High-pressure pressure controller triggered in
cooling circuit. No heat.
A
In heating mode
A1 Insufficient flow rate
A2 Slider closed
A3 Heating circulation pump not running
A4 Overflow valve incorrectly set
A5 Heating curve set too steep
B
High-pressure pressure controller actuated
too early
The module switches the respective unit to the
safety state when a malfunction or error occurs.
A1 Check flow heating water (OT =3-5 K)
A2 Open slider. Check flap valves
A3 Make heating circuit pump functional
again/replace
pump.
A4 Repeat overflow valve setting procedure
A5 Set heating curve lower
B
If A can be precluded, check at which heating
water output temperature from the heat pump
the high-pressure pressure controller is actuated.
If the switching point is significantly below 65°C,
it is possible that
B1 The switching point of the pressure controller is
too low (the pressure controller setting has
changed)
B2 The amount of coolant is too high
The cooling technician must be called in these
cases.
