With the boiler reset control, can it be used to limit the water temperature to no more than 150F at any time, even on cold days? Thanks!

If hot water reset is not available for the boiler, then the idea was to mix the return water with the 180 F entering water. However, if we mix the return water how do we deal with the low pressure of the return water in comparison to the high pressure of the 180 F entering water? Thanks...

The coil has 4 rows, so would it be a good idea to have hot water reset from the 180 F EWT through a mixing valve, (if hot water reset is not available on the boiler)? Thanks for your responses.

Yes the valve is modulating with automatic flow limiting valve. Thanks for your answer.

For 2-pipe fan-coils, does design CHW gpm have to equal design HW gpm, or can HW gpm be smaller? ie during cooling vfds on pumps would push more water through fully open valve than during heating. Thanks!

What is the lowest hot water entering temperature which is reasonable for a fan-coil and why?
