Thermostat Rule

I need a rule the will prevent the Fan Mode on my thermostat from being set to ON instead of AUTO. I also would like to prevent the cooling set point from being set below 73. How can I accomplish this?

For the first issue, I would use the trigger of fan mode = ON and the action would be to set fan mode to AUTO. Similarly, for the second issue, I would use a trigger of cooling set point < 73 and an action of setting the cooling set point to 73.

Some of my thermostats can limit the Heat and A/C temp settings internally. Don't know if this would be an option for you. I like it because it's very robust and unless someone knows how to operate the Tstat menu there will be no way to exceed the limits. This even protects from a logical error in a Hubitat Rule.
