EVOHome Amazon Echo Override

[daddypew]

Recently configured full house system with the ATC928G3000 evohome Wi-Fi Connected Controller and multiple HR92 radiator controllers.
After some teething issues, all working fine for over a week with great control.
Then tried to control with IFTTT and my Amazon Echo, which appeared to change the required parameters OK, then cleared manually on the controller, however noticed heating was running all night with no zones calling for heat.
Noticed on each zone that "OVERRIDE" was displayed at the top of each zone, yet no Override in place on each individual zone.
Checked on echo, noting apparent there, so deleted the account links on both IFTTT and the echo - still boiler relay on all the time.
Reset and rebound boiler relay with no improvement.
Factory reset the controller, incl batteries out. Reprogrammed and controller appears to be working correctly again, however each zone still displaying "OVERRIDE"

Any ideas why still displaying OVERRIDE?

I'd like to get working with the remote systems, but worried I'll mess it all up again.

Many thanks in advance

Due to the nature of the problem, I suggest you escalate this to Honeywell Consumer Support on 0300 1301299 as there will be very little anyone can advise from an 3rd integration perspective.
