Not necessarily. You still haven't described the scenario, but I think I can guess: If the temp goes above 79 (greater than 79, so in whole numbers 80 or more) you want the other thing to turn on, and when it becomes less than 75, you want the other thing to go off, right?
If this is correct, then you need to define the triggering events like this:
- Office Thermostat, Temperature Zone 1, Becomes Greater than 79 (basically 80 or above, though if the Nest reports in fractional degrees it'll kick on a little sooner)
- Office Thermostat, Temperature Zone 1, Becomes less than 75 (anytime it crosses the 75 threshold)
You don't want to use
equal to as it could be possible to skip a temp ( 79 to 81 for instance). While that's not likely, the above will always fire when those thresholds are crossed, so it's a safer implementation.
I can't answer your other question since I don't have a Nest and don't know how it's implemented.
