I woke about 4 AM and since I was up, I checked the GW. It was at 180 (currently running aquastat at 192), but maybe the load had gotten hung up earlier. Anyway, I reloaded then so as to not have to reload in an hour or so. When I went inside I realized the main zone was at 63 with the 'stat set at 67. I let the oil burner come on and it ran about 1/2 hour, during which time all zones save two turned off. Unplugged the oil and went back to bed. (It was -3 °F at this point).
Got up about 6:30 (now -5 °F and the big zone (approx 832 [\])was still only at 64, so I plugged the oil back in. Less than 1 1/2 hours and the zone was back to 67. But that's when I found out that the master bd zone (approx 408 [\]) was at 61!! WTH?!?
I checked the circulators. The larger zone was set at 'High' (Grundfos variable speed) and the smaller zone was set on 'Med'. I moved the latter pump up to 'High' but it's been set at 'Med' since it was installed and I have never seen this happen before. I put my ear to the pump when I up-shifted and I could definitly hear it speed up.
It's almost like someone cracked a window back there!! >:-(
Not really a "boiler room" issue I know, but I'm open to ideas . . .
