Time delay for 1 pipe steam
I think im ready to try to use a timer based method to control my oversized boiler and help minimize the cycling on pressure. I know that @PMJ
has put a lot of time and effort into this control option'; it would be great if he could weigh in!
My boiler is oversized by about 50%. I know its generating too much steam too quickly because the rads are always whistling. I've added a bunch of main venting as well as a vaporstat set to cut out at 0.5 psi and back in right before zero. Once its up to temp and pressure it cycles quite a bit on pressure. The off cycle is only long enough for the system to depressurize (i dont think the rads are taking more steam). I feel like it would be beneficial to my system to keep it from firing back back up for 5 or 10 mins after it cycles off on pressure.
Any suggestions on the best device for this task (adjustable would be preferable) and how to wire it up to do the desired task?
