Coleman Mach 48000 series, no heat from heat pump

[KamFlyer]

Now that it is starting to get a bit cooler we are finding that the front heat pump in our 2019 Solitude 374TH doesn't want to work in HEAT mode.
Everything else seems OK, the A/C's work, the gas furnace works from the rear thermostat but I cannot get the front to work on Heat.
When I select and set a temp above the room ambient, the word HEAT starts to flash. According to the doc this indicates the heat pump has gone into lockout. If I'm reading things correctly, as long as the setpoint is within 5 degrees of the ambient this lockout should automatically clear after 1 hr 45 min but it never does.
Am I missing something? Any suggestions?
Thanks -Rob-

Figured it out. Despite what our sales guy told us, our rig does NOT have the heat pump option in the front A/C
Having a HEAT setting on the t'stat confused the issue and that was one item we neglected to test during our PDI.
Live and learn.
