Hi - I have a two-zone forced hot water baseboard heating system with gas-fired burnham boiler that is used to heat the basement (one zone & thermostat) and a family room on first floor (second zone and thermostat). Problem is that the family room won't heat properly unless the thermostat in the basement is set high enough that it is calling for heat also. So if we set the basement thermostat to 55 or so, there is essentially no heat in the family room. When the family room thermostat is calling for heat, the circulating pump runs, but the boiler doesn't fire. Basement thermostat seems to control both its circulating pump and the boiler just fine. Looks like it might be wired so that the boiler itself is only connected to the basement thermostat. Is this likely the problem? is there a simple way to re-wire so that both thermostats can fire the boiler? Looks like the second zone (family room zone) may have been added later...Is it possible that this boiler can only accomodate one thermostat control? Just bought this old house, and slowly finding all kinds of crazy issues...
