Hi,
Myself have replaced my existing old Wei Mclain UHE Two boiler/Indirect hot water system with new Two Weil-Mclain Ultra 155 which controls 13 baseboard Zones and 1 Indirect Hot water Heater zone using LEAD and SLAVE setup. LEAD is primary source and SLAVE will kick off if LEAD is running more than 10 Minutes to support heating demand.
Since i have installed new system, I am getting banging noise when one of the zone is closed and I cannot figure out what is the root cause of the issue and what I can do to troubleshoot to find out root cause so I can remediate
System uses the Taco 0014 for Secondary(Black) and 007E for Primary Circulator pump(Green)
I have attached actual picture as well as Weil Mclain diagram which I followed for you to understand how it is setup
To avoid extra pressure from Primary Pump, i installed Differential Pressure By Pass Valve shown in separate picture later in stage but I am having same issue.
Can someone please help me to figure out to nail down this issue. Noise seems to be coming close to room where baseboard heaters located. Noise is not coming from baseboard heater, it is pipe noise. ?
Note: I have made sure there is no air in any of the zone
My guess is Boiler pump Taco 0014 is high powered on return line causing too much suction when zone valve is closing
