Upon arrival found back hallway hot and humid. Called for cooling from thermostat and inspected rtu. Found system cooling properly with no alerts on control board. Thermostat mounted in exam room #5 where door is normally closed. System is running until room temperature is satisfied but not until hallway temperature is satisfied. Thermostat is Honeywell 8000, possible option to install sensor to thermostat and mounting in hallway. Unfortunately, if we did this then exam rooms would be much colder in summer and hotter in winter since the system would run until hallway, much larger space, is cooled or heated. Right now I advised employees a way to help regulate temperature is to have exam room #5 door propped open, this way the hotter air would enter the room and be picked up by thermostat.
