I too have now created a Custom action which sets all zones to a Low set point. The thing is that now with the new Warm Weather shut down feature, it looks like the Heating is actually set to OFF, because all the zones have the Heating Off icon and the Heating Off set point, rather than the one I set in my Custom Action. It caused me some confusion at first because I thought my Action was still stuck on Heating Off as opposed to my Custom Action. I really think this needs another icon to show when the Warm weather shut down is in play on a zone rather than just showing it as Heating Off.
