use 2-stage stat to override outdoor reset?
Is there an easy way to wire a 2-stage stat such that, when the 2nd stage is called for (typically when room temp is more than say 3 degrees away from set point, e.g. during recovery after setback), this overrides outdoor reset and runs the boiler flat out until the 2nd stage is satisfied?
If stats had a 2nd stage output that is NC (normally closed), this would be easy, I could just run the outdoor sensor wire through this switch. In fact the stat output is NO, and switching NO to NC requires an external relay, which I am not eager to do unless I have to.
I'm thinking maybe there is a smarter way to wire it? Or maybe a commercial product that does what is needed?
