Hello. My hvac system uses a ac/heat pump and oil burner. My oil burner uses a 2 wire system( T and T). I am able to get the ac and heat pump working however when using aux heating the oil burner never comes on. The oil burner will work if I jump both T and T wires. How can I get this wired and configured in the nest thermostat? Thank you
