I have an Erie boiler Boss controller Model MR31 with priority zone. The only zone that will heat on cold nights is the zone designated to priorty zone 1. Is there a way to shut off the priority option or a different way to wire thermostats. I have an outdoor wood boiler that is suppose to heat 5000 sq/ft for a 2000sq/ft home. If I turn down the thermostat for the priority zone my other zones will heat no problem.
