My question is:
Basement Air RVP Model 653A871.

If the air is running when there is a short but complete power loss at the pedestal, is there a "Time Delay"¯ in the system somewhere that will protect the compressors from trying to start up under pressure?

I know that the compressor motors are "Thermally Protected"¯, but I really would rather have a "Time Delay"¯ so that no power is feed to the compressors for a few minutes.

I know that there is a "Time delay"¯ built into the Thermostat to prevent the 2nd compressor from restarting after it has been "shed"¯ so that it cannot immediately try to restart if full voltage is again restored quickly.

But it appears that the only protection after a short but complete power loss is the "Thermally Protection"¯ on the compressors, and that means that they will try to start but cannot.

Am I right on this?

Thanks for your thoughts.

I'm not an expert but I think you're correct Logthumper. I have the TRC surge protector on my coach, so it provides a built in delay of two minutes before replenishing power in the coach (saves A/C compressors).

I read somewhere that there was a 2 minute delay on the compressor. You might want to give Winnebago customer service a call to verify.

Yup. There is a time delay before the compressor tries to start back to allow head pressure to drop. Believe it is 2 minutes.
You can check this easily. After starting the air conditioing and having it on for a minute or two, shut it off and then turn it right back on, it should not start for about 2 minutes, the fan should but not the comressor.

On my 2001 Adveturer 35U with basement air there is a delay if you turn the system off by the thermostat and then turn it back on however the compressors will immediatly try to cycle if there is a power failure and the power is restored without turning the system off using the thermostat first. I have a surge guard with a two minute delay to prevent this from damaging the system along with a Hughs Autoformer for brownout protection.

Regards,

You didn't mention whether you were on 30 amp or 50 amp at the time you ;ost power. If you were on 30 amp there's a delay built into the EMS.

Last month the Winnebago rep at the Grand National explained that if you're on 30 amp the EMS won't restart anything for 2 mnutes after it's been shut off (in this case by loss of power). This is to avoid overloading the system.

Yes if the air has been shut off that is the case however since the thermostat although it is controlling the 120 volt AC unit it is also controlling the 12 volt heating system. If the 120 drops and comes back on of its own without someone turning off the thermostat then the stat will still be calling for the compressors and will not delay when the 120 is restored. At least that is how it worked in 95 and continued to work on the 2001 model. I proved this out just a few minutes ago on my 2001 Adventurer.
