Coleman Mach 8232 series to Atwood
I have two ancient (2003) Coleman A/C units which are ready for replacement. The system is run by the Intellitec 00-00591-200 controller and a no-longer-available Climate Controller also by Intellitec...

Well push is becoming shove. I need to order the A/C to get them here in time for me to replace them.
In order to achieve the desired upgrade to the Intellitec thermostat, which I now realize is what I am really wanting to do, and maintain the Intellitec functions for shedding, the options come down to doing everything the same for the new thermostat - which is to modify it so that the on/fan-on case is interruptible and the compressor-on case is interruptible for shedding purposes. These are all the same - I can do it with small relays in line so that if the Intellitec says that the shedding should occur, the relay will drop out disconnecting the thermostat. This means as many as 5 relays per unit (I think fewer because the fan uses a common, but whatever that would be worthwhile.
To replace my units with larger ones, requires that a Coleman of approximately $1000 is needed. That is $2000 plus cost of thermostats ($100) and shipping ($200) puts it in the very difficult situation. The Atwoods would cost $700 including thermostats or $1400 plus shipping ($200).
To replace with a Mach 3 Coleman is about $1200 plus shipping and no upgrade at all.
You can see why the Atwoods look pretty good to me. But if I replace them, I might spend most of my time at the lake in Oct trying to get them to work.
