Hi, I have a question for you guys.I have a Buderus Logano G215 boiler just for baseboard heating. It has a new Honeywell L7224u 1002 Aquastat installed last week. I also have 3 Grundfos zone valves with circulation pumps for each zone and each is set to med circulation.. It is an oil fueled boiler.
Now before last week the heat was fantastick, rooms would heat up fast and boiler wouldnt fire for a while. On Friday while I was at work 3 hours away my wife calls and says there is no heat. I have her check the boiler and it blew the fuse. She resets it at the fuse box and boiler powers on. She says she hears the boiler make noise but I think it was the circulator pumps turning on, not the boiler. Water was also leaking for the air vent on top of boiler. Temp in the house showed 47 at the thermostats. After an hour she calls me back and the temp only rose to 48. I called for emergency service and the tech came and changed the air vent and said the Aquaststat needed to be changed. The new one is the L7224U 1002 all i know about the old one is it was Honeywell also.
Now my problem is that the rooms dont get hot like they used to. Temp on the Aquastat says boiler is 183 but the temp on the boiler with the gauge is around 160. The Aquastsat has been set to 180 hl and ll off. Is the Honeywell faulty? Or not programmed correctly? And basically is there anything I can do so not to get charged another service fee?
At night with temps here below 0 I hear the boiler firing about 5 times an hour with the 55 degree setting for overnight. Also some zones dont really get that hot but the pipes are hot.
