Uponor
Stainless-steel Manifold Assembly, 1" with flow meter, B&I, ball valve, 12 loops
PART NO.A2701202
In a new install, why would I pick a 4 wire over a 2 wire thermal sealed actuator? What would determine this?

4 wire means it has an end switch to trigger the boiler or a pump. If you have multiple thermostats you probably want 4 wire.Bob "hot rod" Rohr
