You don't need a delay. The Coleman compressors have their own internal short cycle delay. The delay will not allow the compressor to restart for about two minutes when power is lost or shut off. This is to let the pressure bleed off prior to restart.

WRONG. The delay is built into the wall tstat. Doug

You are correct in the OPs case...
However, my system of two ducted Coleman A/Cs uses the Intellitec ECC and there is NO delay in the wall thermostat.
I was incorrect in stating that the A/C compressor contained the delay, when it is actually located in the ECC controller.

Your RV is 18 years old. Lets try to keep advice on at least RV's built in the last 10 years. THAT is what my expert advice is based on and the fact that the OP stated he was buying NEW tstats. AS to your case. IS the EMS Intellitec the one Fleetwood used back then that BOTH AC units were controlled by that ECC system at one wall panel that had a slider control for temp adjustment for each AC? If so, that system was designed just like the older RVP wall tstats. Since the system did not use a RVP built tstat, Intellitec incorporated the delay into their system. Winne and Fleetwood both used that system back then. Doug

I case you can't read, the OP's coach is ALSO 18 years old, and could have the same (or similar) system that I have. Your comment is absurd and insulting (as you no doubt intended).

If you don't know the difference between the Intellitec EMS and the Intellitec ECC, your "expert advice" could be suspect. I won't waste my time explaining them to you, but I can point you to the information.

Thanks I will get the thermostat without out the delay.

You do not understand. IF you are buying a RVP tstat, it already has the delay. Doug

Most residential stats have a setting for "heat anticipator" which is needed for home furnaces but is not used for rv's. Your time delay is built in to the heater control panel and there is no time delay in the stat. There may be exceptions to this but I'm not aware of them.

Wrong also, The delay is built into the wall Tstat. Doug

ALL current RVP wall tstats have a compressor time delay. Post the P/N of the Tstat you purchased. But, NO, you do not have to have the delay. The delay is just a convienance factor for RV'ers that would attempt a quick restart without allowing the compressor head pressure to equalize. Doug
