Troubleshooting
This section shows you how to recognize and understand possible operating errors.
For correct fault tracing Dantherm strongly recommends connecting a remote control or PC
with installed PC Tool or the Dantherm App, that works with the unit.
Errors are displayed on the HRC3 remote control with "E” + a number. The issue can then be
looked up in the troubleshooting overview and in the control panel manual to correct the
fault.
Operation warnings and faults are logged in the controller memory. Connect a computer
with PC Tool installed via USB to get detailed information from the log le.
Possible faults are shown on:
Appliance Signal
Unit Acoustic buzzer signal from the main PCB. Connect a remote tool or
PC Tool to view the specic error.

The number of ashes corresponds to an error code followed by a
pause of 5 seconds.

longer period of time.

Errors shown on the display contain three numbers or letters. E.g. "E12” means error number

After completed inspection or repair of possible faults, the unit can be reset by disconnect-
ing/reconnecting the 230 V AC power supply. This resets the controller and the unit starts
normal operation and also restarts a new search for possible errors.
This can take up to 15 minutes.
