Hey guys, new member here, so a little background history first. Im an hvac guy since 01', i ve only recently started to get into advanced hydronics and boiler systems. Pretty much been a forced hot air tin knocker my whole career. Im really startn to dig the controls aspect and high effeciency stuff nowadays. So this past year, my wife and i took the plunge and decided to build our own custom home in nj, on the jersey shore. Its a nice 2400sqft 3bdrm, 2.5bath 2story with a basement. I decided i wanted to over complicate my life and stray from my comfort zone alil bit. I have a spray foamed house(open cell), entire house is completely sealed and within the thermal envelope, natural gas Navien ncb240 combi mod con boiler, 2 zones(1st floor/basement and 2nd floor) air handlers with hot water coils atop each. My ductwork is sealed tight and insulated, and completely hard piped thruout the house. We used Honeywell ERVs for each system(vnt5070) and are using the honeywell prestige iaq system(equipment interface module). So far everything is going great and house is comfortable. We only just moved in couple weeks ago. But i pretty much spent all winter watching the heating system run n operate. I ve been taking notes. Wasnt making any adjustments bcuz house was still being worked on n built. So to many variables still existed. Now, id like to start dialing in my system n could use some help fine tuning. So for the long winded post, but i know the more details, the better. I originaly had a well respected tradesmen help me design my system and control strategy. Unfortunately, i believe his health has declined and is hard to get a hold of. I truly hope he s ok. I ve known him a few years now.
Id like to really fine tune my boiler and get it to run those infamous long n slow burn cycles. I have general knowledge of basic info, settings, and perameters. On colder days, it ll run 10min cycles on/off, back n forth between both zones calling. Im using an 80gallon buffer tank to help with the hydraulic seperation and micro zoning.
