Where are the thermostats? Or do they use duct stats? What have you checked so far?

Each room in each floor has a thermostat and I have played with each one of them but no hope
The thermostat works on compressed air, the main line that comes out of the air compressor was broke
And leaking air, after repairing it the pressure is 60 PSI so it’s normal.
I’m almost sure it’s a small problem somewhere but no clue. The air flow does not stop into the building
Plus it is freezing cold 24 hours. I’m not sure if it needs to rest or?

Somewhere you will have your pneumatic control panel. Check to see if one or more of the transducers are bad. One of the pneumatic stats may be bad and keeping the unit on.

Those stats are most likely reverse acting, so you may still have an air problem. The control panel should have the pressures you stats work at, make sure they are getting that pressure, and that it is coming back to the transducers/actuators.

Do you have reheat coils in the system? If you do make sure the heat is on to balance the temp with the humidity. Check your rooftop controls mixed air stats and all dampers, end switches etc.
