Looked at the thermostats this morning to see the inside temperature 2 degrees higher than the set point for the one that controls the OWB heat. That seemed odd - it was like that last weekend too, but it was so nice and sunny out that I attributed it to sun load heating up the house through the south facing windows. This morning it was cold and too early for the sun. Turns out the programmagle thermostat for the propane furnace was set 2 degrees higher just on the weekends during the daytime! I don't know how I missed that - it must have been set that way from the spring after the OWB was shut down.
In any case I'm kicking myself for using $$$ to heat the house on the weekends for the last few weeks! I apologize in advance to the AS community.
