Hjet ecs temp control

What is it and where is the control?

I must be crazy but searched everywhere I could think of and can’t find it. I have an ecas message that will not go away that says ECS temp control manual. How do I make it go away - its annoying!

There’s an environment page in the GTC.

I found the Environ area in the GTC which displays on the MFD but don’t see a switch there.

Aircraft Systems > System Controls > Thermostat - change it to Auto on both tabs

Thanks Majorlag9496, that did it. A very obscure setting!
