Jayco AC Unit: should it run 100% of the time?

[caveeagle]

Recently purchased a 17' Jayco Featherlight to use on my property for a guest cabin. Is the AC unit supposed to run 100% of the time? Only controls I see are: Fan-Hi/Low and AC-Hi/Low and a temp knob the turns from red/blue. Granted, it has been pretty hot and humid this summer, but even...

I have it powered through my barn which is on its own meter, so I can see what it is costing me to run this thing.

The fan may. May depend on the the thermostat.

It seems like it is blowing cold air all the time. Does this seem normal? Or should a roof top system have some sort of internal thermostat?

FWIW, the roof top AC is an Airxcel 48000 series

I assume you have a wall thermostat?

 

[caveeagle]

pretty sure there is not a wall thermostat. I don't see on in any obvious position. Is it unusual for something made around 2017 to be without one?

Is one of the knobs a reostat?

Is one of the knobs a reostat?

I am not sure.
One knob is: Fan-Low, Fan-Hi, AC-Low, AC-High
The other knob: Is Blue/Red, for temp control?

Does it have clear stops or move from high to low without any steps?

No steps, that is your thermostat!

I will double check, but pretty sure there are no 'steps' on the blue/red dial.

So is the system supposed to turn itself off when it reaches a certain temp? It seems like it just keeps running

Seems like having an "AUTO" option would allow the fan to come on and off as needed. If it only shows on and off, that is probably all it would do.
