    Controller for low pressure steam.

    I have not been able to find a control to operate a modulating burner at appropriate low pressure for a typical steam space heating system......about 1 psi or less. Honeywell has dropped thier 0 to 135 OHm low pressure controls and has nothing to replace them. Johnson has nothing either. Honeywell's new 4-20 mA pressure control operates down to about 2 to 3 psi....so it is also not appropriate. Any ideas out there? We have ordered the burner with 4 to 20 mA input, since this is where most modern controls appear to be going.
