I just replaced my Sear,s hot water boiler with a newer {1990} Lochinvar hot water boiler.The old system {Durocraft program.} when set at 70 would come on at 69 and shut off at 70, or would come on if raised to 71. Now it holds itself at 70 but will not come on manually until raised to 73-74. A couple of times it did not come on at all. The wires to the boiler are wired the same as the Sear,s and nothing was changed on the thermostat. Does anyone have any ideas why something changed . I prefered the way it ran with the Sear,s Thanks Greg
