Vaporstat, which one?

Tom_4

Can someone tell me which model vaporstat I need for a gas boiler piped to a moline steam system. Thank you

L 408A 1132

0-4 psi

The 0-4 psi is the L408A1157 or the L608A1053 that is spdt but will work fine too just connect r an b.

I find the 0-1 PSI more sensetive under a pound

and that Moline system should run at well under a pound. The 0-4 might act just like the P 404 A on that system, in my experience.

Thanks Noel

I should have focused on the "Moline" part of the question. Since the ideal range for a control is the center the lower range option would be best. I must say I have never used the 1132 since I'm usually looking for 1/2 to 2psi accuracy and the boilers here are usually way oversized and the less short cycle the better.

Thanks for the info
