6 Using the heating system – Troubleshooting

✎

See the “HDG Control” operating manual, chapter “5 Using the
control unit”, section “5.3 Switching off the heating system”.

Switch off the emergency heating switch (if installed) or the
corresponding mains electricity circuit breaker.

✓

The heating system is switched off and without current.

6.6 Troubleshooting

If a fault occurs in the heating system, this is shown in the display of
the HDG controls.

✎

See the “HDG Control” operating manual, chapter 10
