Glad to assist! Let us know how you make out. Also you might already be aware of this but I'll tell ya anyway. When looking at your water to air HX's inlet/outlet they are offset, the low one is the inlet and high is the outlet. Flow is better that way and air purges through better also. Secondly, when installing my system most diagrams shown the incoming hot water flow going to the water to water HX (domestic hot water) first, then to furnace. I feel/felt that I want a warm house first and the heat that is left I'll heat my hot water. So my flow goes to the furnace HX and then to the hot water heater HX. Works great!!! I still even had to install a mixing valve on my domestic hot water cause it was to hot. OWB settings are 160 on 168 off. Just a thought. To each is own.
