Error code
Service
By pressing the SERVICE button, the ventilation symbol
and an error code appear on the screen. This error code
allows you to determine the cause of the error.
The thermostat may be paired with an existing Itho
Daalderop ventilation unit, which does not support this
functionality. In the event of an error, only the ventilation
symbol with the text ERROR CODE will appear on the
screen.
If another device has an error at the same time, the
INCREASE or REDUCE buttons will be visible. By pressing
these buttons, the various errors can be viewed. The
small grey digits show the serial number of the error.
For an overview of the various error codes,
please refer to the manual of the ventilation
unit.
