Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. First I’ll need some more info so I have a more complete picture of you situation.

all I need to know is do I connect to p2 with white coming from thermostat?
Expert:  Rick replied 1 year ago.

The LWCO is usually wired into the control circuit not to the thermostat. I need some frame of reference. So far I have no idea what you have for equipment. I can't help you without this info. I need boiler model (located on the rating tag) and brand and model of the LWCO.

I've attached the manual for your boiler. Wiring diagram is on page 13 for electronic ignition and page 14 for standing pilot (lit all the time).
