Had a long talk with Dometic today. I will say that they were busy but they did call me back within a 1/2 hour or so and the gal was very knowledgable about the product, just as she should.
This remote.. as well as all their tstats can be 3-5 degrees off. Sounds like quite a bit but this is the way it is. This explains why we can't set temps that we are comfortable with like at home.
The unit sends discrete commands so if you don't hear it beep when setting 74 deg. and do hear it beep on 75 deg, the receiver did get the 75 deg command.
Although the remote has a reset that resets remote funtions, if you point it at the receiver and do a reset, it resets the receiver as well. I did not know this. This is to be done when the controls don't work right.
In my case since I already own it, if I choose to go back to a regular wall thermostat, I just can't swap to the "Hunter home Tstat" because of that darn RJ11 phone wiring they use. Not a big problem, it just requires buying their "Comfort Center" Tstat(which looks pretty nice and does multi zone) and a new control box that goes in the A/C unit itself. I don't know the costs of these yet. She did give me the Part #'s though. If you wish to use the analog tstat (which includes the hunter types), you would have to get an analog control box and tstat as well as replace the wiring to the standard stranded wires which could be a pain depending on routing.
She gave me other tips for helping out with my A/C freezing up even on high fan and I am going to use it the rest of the summer and into the winter before I decide to keep this system or not. I do want to give it a fair chance.
