If your thermostat has a mechanical fan/auto switch, you can use a 230v/24v transformer to feed power to the condenser contactor and the indoor fan will come on. If the stat is touchscreen or has a push button fan switch, you're out of luck
New to the field, we have been working on some split sys last week. Has any one wired them up so that you could jump out the blower from the outside for troubleshooting and servicing to keep from going all the way inside to the tstat to control it? These are new start-ups.

Xformer is outside. I just wanted to know if it would be anything wrong with leaving a caped free wire connected to the indoor AH on "G" that when I cam back I could jump to R and bring the blower on so I would not need to go inside to service/ts outside unit? (info AC only commercial split long walk to tstat)
I do that all the time when I Install new units, Makes life easier when servicing.
