24/7 Room F thermostat hissing(Air) sound from Wall

Loud hissing sound from thermostat in room F in the 24/7 area. Someone either hit the thermostat with a chair or tried to adjust it and pulled it off the wall slightly. The sound came from a very small air hose that is in the wall that leads into the thermostat. The thermostat has 2 small pipes in the back that enter the two air hoses from the wall. I readjusted the thermostat and pushed it back on the mount and made sure the pipes entered the air hoses and the noise stopped.
