Troubleshooting; Volatile Lock Outs; Temporary Errors - Winterwarm Qwikshift QSG Installation Manual

9. Troubleshooting

If the air heater malfunctions, first check if the problem is
caused by external circumstances (e.g. no supply power).
If the problem is not caused by external circumstances,
use the tables and instructions in this chapter to fix the air
heater.
NOTICE Please remember the built in waiting times of
the air heater; the signals of the LED's and the code on the
display. Do not react too soon.
The error codes below, refer to the gas booster of the
hybrid air heater. The error codes of the connected heat
pump are visible in the Smart Controller too. Consult the
manual of the heat pump for details.
