Why doesn't the TEC3000 zone temperature change fast enough on my Johnson Controls Fan?
The TEC3000 is configured by default for larger spaces with normal-sized equipment when a proportional device is active. Select Control Setup >Tuning > Equipment Size > Oversized.
Why does the zone space temperature change too much in unoccupied mode on my Johnson Controls Fan?
The heating and cooling equipment are too big for the unoccupied space. Decrease the Unoccupied Off Delay parameter from 10 minutes to a more appropriate time for the equipment configuration.
How to fix 'Outdoor Temp Fail' on Johnson Controls Controller?
If the Johnson Controls Controller displays 'Outdoor Temp Fail', first check the wiring of the sensor. If the sensor was intentionally disconnected, reset sensors through the menu.
