Can someone let me know if the Aria 3901 has both heat pumps and a furnace? On the main Bluetooth board on wall outside 1/2 bath, it has a button for “heat pumps” and a button for furnace. We live in FL and have not used the heat before and are confused as to whether the heat pumps and furnace are one and the same or two different entities. If two diff entities, where is the furnace located?
We are very new to all this and have much to learn! Ty in advance for any help/advice.
