Partial disarm

[Konnexman]

Hi !
We have a client that has the following situation:He has 2 zones;* One is the restricted zone;* the other is the gardner zone;The owner when he leaves home, he wants to arm everything;But when the gardner comes to the house, he must disarm only his own zone.We were thinking on making a bypass for his zone with a knx action, but for that, the gardner is detected before being able to do it, and so it doesnt work as the count down continues.What do you suggest that we make ?
Best regards,Nuno

The gardener start the entry delay
Make a Knx button to disarm the whole system but immediately re-arm but bypass the gardener zones
For security he should enter a code
