Thermostat with no feedback

[u/Zelltribal]

No idea how to read this thing. I’m guessing it’s night/day but is plus warmer or cooler, no idea how warm or cool. I just know it’s too hot even though it feels like the air is on. Interior of the building is cooler but by the windows it feels like the heat is on.

You will need the serial number.

Good luck!
