You may have less chance to use economizers in your area.

I don't know what kind of enthalpy control was behind louvers in wall but will be back there soon thanks guys.
Don't have unit mn handy York ah with 4 stage solenoids cooling york condenser was there for a air balance and got asked to look into econo.
A churches major load is in the cooler morning hours. When the outdoor air temp is below 55-60 when an economizer should be used. In addition to all the other great comments mentioned it will also save on compressors. Why run compressors under 55 degrees OA temp if you don’t have to? Especially in a church setting. You get people, house and stage lights, amps for a band in a space your goanna need cooling.
As for it keeping up. The space doesn’t care if the 55 deg air is conditioned or OA. Hook the economizer up, let the church use the savings in other ministries.
Always leave it better than you found it.
Ya we are in California central I don't know how many days in the summer that will be below 55 in the mornings and they are never there at night. I will encourage them to repair it. Are there any tricks into faking the enthalpy control out?
here's honeywells economizer checkout manual. lots of usefull info.

A positive attidude will not solve all your problems, but it will annoy enough people to make it worthwhile.
To be honest, regardless of the application (church, office building, etc.) the ability to run free cooling is a bonus. Depending on what part of the country you're in, you may see a dramatic cost savings when it comes to your energy bill. If your calling for 65 degree air and its 63 degrees outside, doesnt make much sense to run mechanical cooling. That being said, make sure you understand enthalpy controls.
There are...you will need resistors.
