Find the perimeter wall. Not the walls,it is just outside. Hover until it turns blue, click on it to make it yellow.

On the Tool Options panel click Options. You should be able to click off automatically generates panels. I clicked off all options to be safe. Good luck.

Roof a/c's wont come on unless you set temp to 55 degrees


Tried another thermostat? Also check that where thermostat is mounted isn't a warm zone, that is detecting higher temperatures. Put another thermostat on wall beside it to check. Another thing is to take thermostat of the wall and let it hang and try it. I've had some where warm air was blowing/sucking past hole for wiring in wall, and throwing thermostat off.

There isn't much to these things, its either the pilot generator or the gas valve. Or maybe both, try the first, then the second.
