Max Change and ATO Question?

[PMG]

Below is the code I am planning on using to control my ATO.
SwitchA3 is the primary float switch, and SwitchA2 is the secondary float switch in case the SwitchA3 fails.

Am I correct in assuming that the code below will run my ATO pump until the float switch is triggered to turn it off, and will not turn on again for 60 min.?

Also, Am I correct that this code WILL NOT in any way shape or form make my ATO pump stay on for 60 min.

If SwitchA3 OPEN Then ATO OFF
If SwitchA3 CLOSED Then ATO ON
If SwitchA2 OPEN Then ATO OFF
Max Change 060 M Then ATO OFF

You are correct; the Max Change will block ATO from turning on for 60 minutes after it has been turned off.

Note: If A2 and A3 are backup for one another you can save a switch input and wire the switches in series so that either one opens the connection.
