Come on rocket, you said the primary system would maintain
the temperature even though it could not handle the setback,
so this means it is then sized for the heating load

You did manage to get that bit right. ****ing miracle.

and by your own admission, can not
handle the setback, so you have a booster.

Mangled that completely. I ACTUALLY said that you can EITHER
let it come back off the setback after midday in time for the normal
temp in the evening, if no one is going to be home during the day,
OR you can use a ductless split system to come off setback
if you prefer to come off setback before anyone gets up.

Do TRY to keep up. Laying off the grog might help.

Now the problem is that something sized for the heating load,
which then can deliver a significant amount of heat from a low
temperature source, is going to have much more capacity
than needed for cooling unless of course you live in Bermuda.

Or you dont actually use it for cooling. A swamp cooling system
makes a hell of a lot more sense here, vastly cheaper to run.
And you can use the heat pump on the very occasional says
when the humidity is too high for the swamp system to work well.

I thought when you were pitching 3 systems you realized this problem.

Not a shred of evidence that you are actually capable of thought or
even being able to keep straight what is actually being discussed either.

At least you sort of had all your bases covered then, one sized
for the cooling load, another sized to make up the difference
needed for the one sized for cooling's heat output vs the
required heat output, then a third system system to finally
prove you could accomplish set back and then recover in time.

Nothing viable in the above.

Wrong, as always.

So try to increase your batting average then, you finally got
a hit when you realized that in the warmest time of the day
you would have the maximum heat output from a heat pump.

I knew that all along, just rubbed your nose in it when you were
stupid enough to proclaim that setback aint viable with heat pumps.

Maybe you could just summarize one of these
viable systems that covers all the bases.

Pointless, it makes a hell of a lot more sense to
tailor the system to the way its going to be used.

Come on bottom of the ninth two out and if you hit a
grand slam, you got a chance of losing with dignity.

Couldnt bull**** its way out of a wet paper bag.

Try laying off the grog for a while and see if that helps.
