This section shows how to acknowledge and understand possible operation errors.
For a proper error search, Dantherm strongly recommends to have a remote control con-
nected and operative with the unit.
Any possible error will be displayed on:

Acoustic buzzer signal from the main PCB. Connect a remote or PC
Tool, in order to get the specific error shown.

trol (HCP 10/11)
Acoustic buzzer signal and flashing LED. The number of flashes cor-
responds to an error code, followed by a 5 second break. See Error list.
PC Tool
Displaying error number, as well as being able to log specific opera-
tions, over a longer time span.
Smartphone APP

Error displaying on a display, is a three digit information, for instance “E13” which means error

After completion of any inspection or repair, due to possible errors, the unit can be reset by
disconnecting / re-connect the 230V AC power. This will reset the controller, and the unit will
start normal operation, and also restart a new search for possible errors. This could last up to
15 minutes.
