I just bought an old house with a Burnham Jubilee boiler. It most be at least 40 years old but checked out fine when I had it cleaned out and serviced. My system has one circulator and three zones. A honeywell aquastat L8024 controls everything. Lately I've noticed that the circulator is running even when the thermostats are off (not calling for heat). It doesn't run continuously but does run when I think it shouldn't be (all thermostats are off). Could this be normal operatation or is something wrong? Thanks in advance for any help.
