Recently installed a Crown Royal 7350MP and a heat exchanger into my plenum of my oil furnace. Everything's ready to go for the cold months, but am having an issue figuring out how to install the second thermostat to run the blower only on the oil furnace.
Oil furnace is a Rheem ROBC-130RBJA and has the old school double "T" connection for its' thermostat. I am not a HVAC expert by any means, but am pretty handy with electrical and other trades.
