I wanted to make a “maintenance” button for the AC’s… meaning… if they are “on” now… they should go immediately in OFF state. (we are talking 5 channels per AC).
Now, normally you would do a FORCED OFF… but then if the AC gives the queue for “demand” it would be ignored even after we cancel the forced off - so the AC would never come to life again
So I went for the inhibit - which would still see the “demand” but it would not switch off - so i added the OFF as well (fans with delay to get rid of excessive cooling) …
but… what if the AC was on (at the time I set it to maintenance mode) and now I return to normal mode… it would still ignore the previous demand from the thermostat and it would not receive a new “on” command…
what would be required to essentially “keep” the previous state before I shut it down… so I can resume afterward - or can I instruct the thermostats to re-send their current state?
(a virtual relay could help, but as said… its 5 channels per AC - so we are talking 20 virtual channels then…)
