Will this work?

[bowfront]

Forgive my ignorance I'm just getting started with an AC Jr.
Last night I played around with a couple of combinations to get several fan wired together to stay on all the time when the halides are on and then be temperature regulated when the halides are of. I tried something like this

FA1 = fan I'm trying to control.

If time > 14:00 Then FA1 ON
If time > 23:30 then FA1 OFF
If temp > 78.5 Then FA1 ON
If temp < 78.0 Then FA1 OFF

That works partially but when the fans are turned off after 23:00 they come on when the temp goes over 78.5 but only very briefly and shut off when it's back down below 78.5. I want them to work like my chiller does and come on at the high set point and stay on until the low set point. I guess the last time statement turning them off after 23:30 is trumping the temp statements.

Anyway will something like this work instead to do what I want?

MH1 = first halide on and last off
FA1 = fan I'm trying to control.

If timer MH1 = ON Then FA1 ON
If Temp < 88.1 Then FA1 OFF
Max Change 010 M Then FA1 OFF
If Temp > 88.5 Then FA1 ON
Max Change 010 M Then FA1 ON

Looks like it does what I want it to do. Thanks for all the response and help J/K
