E8 error

Image Added

The Genius Radiator Valve shows the 'E8' 'communication error' if it tries to communicate with the Genius Hub a number of times and fails.

The Genius Radiator Valve will naturally come out of 'E8' when the communication with the Genius Hub is re-established, through the only tries to communicate with the Genius Hub about every 30 minutes when in 'E8' so this may take a number of hours.

To remove the 'E8' error from the valve immediately, so you can change the temperature on the valve, you have to remove one of the batteries for 30 seconds and put it back in again. This communication problem may have been caused if a Genius Smart Plug near the valve has become unplugged or the Genius Hub has been turned off. 

If the problem persists see the article: How to - Genius Position the Genius Smart Plugs.

E9 error
