Re: Variable speed drive

said by garys_2k:

I wonder if a relay board could be cooked up to:
- Receive a call from the thermostat for cooling
- Immediately start the air handler fan
- Wait five seconds, then start the condenser fan
- Wait five seconds more, then start the compressor.

This would allow all the motors' inrush currents to subside before the next one comes on. Starting all three at once is the real b*tch.

Great idea--I even have an ICM TD relay or two around here somewhere. Can't remember why I bought them--probably to avoid contact bounce on my well pump control yrs ago.
