this is inside 7/11 store
according to store manager there is no regular thermostat inside the store.
I looked around and he is right no thermostat anywhere inside store.

could this devise is the thermostat? or the thermostat located at Rtu's
there is only 2 wire inside connected to a small Thermistor

There is no thrmostat. Unit uses data from sensor to control. Get the micro control book and study up.

7-11 keeps the thermostats in the rtu control panels, or at least they used to when I worked at them, to prevent hadji from messing with the temp. Remote sensors were in the returns or directly below them.

that will control a trane by itself if attached to term 1 and 2 on control board it will maintain 72 degrees
