Hi,
I'm a new homeowner and I'm trying to troubleshoot an issue with the circulator pump. Recently, the circulator pump to the hot water heater is constantly running when it wasn't the case before. The circulator pump is controlled by a 4 zone Taco control valve system. The hot water is zone 4 and the light has been on for a few days at least when it was never the case. The pump is triggered by an aquastat on the hot water heater. I'm not sure what the setting for the aquastat should be but I have it at 160 and the differential is at around 7 degrees. The High temperature on the furnace setting is 171. From what I understand, if the water temperature in the hot water heater is above 160 then the circulator pump won't run?
Any advice is appreciated!
