I am trying to create a program for my HVAC where after running for an hour, it turns off the cooling for 15 minutes and runs just the Fan. Then I want it to return to normal operation. If 'Upstairs / Master / Upstairs Thermostat - Cool Ct' is switched On Then Wait 1 hour Set 'Upstairs / Master / Upstairs Thermostat - Main' Mode Off Set 'Upstairs / Master / Upstairs Thermostat - Main' Fan Mode On Wait 15 minutes Set 'Upstairs / Master / Upstairs Thermostat - Main' Mode Cool Set 'Upstairs / Master / Upstairs Thermostat - Main' Fan Mode Auto Else - No Actions - (To add one, press 'Action') Does that IF Condition "Control" trigger every time cooling is called for or only when you set the mode to cooling initially? Should it be "Status" instead.

Correct. "Control" would only see the ON event and not the status change. With "Status" if the status changes to false the THEN block would stop running and the (blank) ELSE block would start running. Let's pretend its a super hot day. The temp in the room rises, the air kicks on, this starts the one hour wait. The hour expires, the remaining parts of the program run.... the Then block is now over... it won't repeat it again. You need a repeat, so that it does this every hour until it's stopped by a change to the Status. If 'Upstairs / Master / Upstairs Thermostat - Cool Ct' is On Then Wait 1 hour Repeat Every 1 hour Set 'Upstairs / Master / Upstairs Thermostat - Main' Mode Off Set 'Upstairs / Master / Upstairs Thermostat - Main' Fan Mode On Wait 15 minutes Set 'Upstairs / Master / Upstairs Thermostat - Main' Mode Cool Set 'Upstairs / Master / Upstairs Thermostat - Main' Fan Mode Auto Else - No Actions - (To add one, press 'Action') I can't decide whether you need the initial wait 1 hour or if the repeat will wait one hour before the first iteration on it's own. (I don't use repeat like this anywhere and the documentation doesn't clear it up, but it's easy to test)

so the programs are working? Or he refilled it?

He came early before I fully tested the programs. I am going to test them using alerts and see if I am getting the desired results. With it being a leak, I am going to eventually need this to work while I wait for the part and install.
