Error codes

It is possible for error codes to be displayed on the control screen. In the event of a malfunction an alarm

will sound and the alarm indicator

will be displayed on the display. An error code or codes will flash

intermittently on the display. If there are multiple codes, the display will continuously cycle through
them. The following photo shows error code “E0” as an example.

Mute: You may mute the alarm by pressing and releasing the wrench button. The red ringing bell and all
error codes will still be displayed. When the fault is remedied the control will return to normal operation
and will automatically clear the codes from the display.

Carel Control

EO = Air sensing probe - Open or shorted
