Here is two shots of existing boiler piping and control panels for circulation pumps, some use wireless programmable therm. Some zones are old Honeywell therm. Hope these come out okay. Anything else you guys need to see or know to give me some advice on install? Okay, it does not seem to want to do two shots. Oh well, this is the newer one anyway. Hey, how do I get two or more shots in a post using the attachment thingy at the bottom of post?
