Frequent questions

Why does the DG801 show "E1" or "E2" messages?
When "E1" or "E2" is shown on the display, the internal sensor is faulty or short-circuited. Contact a Homplex specialist for verification.
Why doesn't the DG801 respond to any commands?
The thermostatic valve was blocked. Press and hold the "Auto/Manual" and "Prog" buttons simultaneously for three seconds to unlock it.
What does the "AdAp" error mean?
The message does not indicate a technical error. "AdAP" indicates the use of the limescale protection function. DG801 reported that the installation has not been switched on for two weeks. So it will open and close the circuit to avoid build-up of deposits.
