Is my thermostat smarter than me?

Woke up this morning, and checked the outside temperature with the Javelina display, it said 55 degrees. So I set the thermostat for heat from the roof air heat pumps.

Then I notice the heat is coming from the propane furnaces. Wondering why, I check the outside temperature via weather apps. They all say 27 degrees. Way too cold for a heat pump. I double checked, and the thermostat was set for heat pump. But I did change it to furnace.

Did the thermostat figure this out?  I didn't know it had the smarts.

By the way, I'm in SKP Park Sierra, outside Yosemite Park.

Ok. I answered my own question. It is smarter.

And, able to run the heat pump down to 30 degrees.

F. AUX. HEATWhen in the HEAT PUMP mode, if the outside ambient temperatureis measured to be below 30°F and the vehicle is equipped with afurnace connected to the Comfort Control Center, the control willautomatically select the FURNACE operation and the HEAT PUMPwill shut down.Important:If vehicle is not equipped with a furnace no heatwill be available below 30°F. IF vehicle is equipped with afurnace and it is connected to its own thermostat, it must bemanually turned ON and OFF for operation.When this happens, the AUX. HEAT and the HEAT PUMP indicatorson the LCD will illuminate. Once the outside ambient temperature ismeasured above 38°F, the control will return to the HEAT PUMPoperation and shut down the furnace if it is connected to the ComfortControl Center. If furnace is not connected to the Comfort ControlCenter, the furnace thermostat must be manually turned off.G. DEFROST CYCLEThis cycle is active during HEAT PUMP operation and allows theheat pump to operate down to 30°F. When the outside ambienttemperature is less than 42°F and greater than 30°F, a defrost timingcycle will begin. The defrost timing cycle will allow operation of theheat pump for 25 minutes. The fan will then be shut off, the refrigerantflow reversed and run for 4-1/2 minutes, this is the DEFROST cycle.The refrigerant flow will then be returned to normal and, after a 30second delay will continue until the temperature is greater than 42°For until the temperature becomes less than 30°F, at which time thefurnace will activate. (See AUX. HEAT). During the defrost cycle, theDEFROST indicator on the LCD shall be

Mine does the same thing when it is cold. Will shift from heat pump to furnace [aqua-hot]. It will turn on the blowers on the baseboard heat exchangers, but it is not smart enough to turn on the diesel boiler or electric elements on the aqua-hot, so unless I turn them on, it will just blow cold air.
