Is it possible to run a 8 loop uponor manifold with thermal actuators using zvc404. I have 4 loops down stairs for zone one. Two loops for zone 2 and single loop for 3&4

HVACNUT

Absolutely.

Caution: If one of those single loops calls by itself, your boiler is going to short cycle quite a bit unless you've already accounted for that.

@hvacnut how should I wire it up?
@Steve minilnich how would I prevent it

Unless I didn't read your post correctly, its fairly simple.

@duartelu86 - It depends on what the water content of your boiler is, the heat loss of the smallest zone, the lowest turndown rate of the boiler if it has one. Describe your boiler and system.
