Humidity Unreliable The zone humidity reading was reliable
and has now failed.
1. If the source of zone humidity was the
onboard sensor, contact Johnson Controls
product sales and support.
2. If the source of zone humidity was a BAS,
check the BAS to ensure that it is still online
and providing the TEC with the humidity
reading. If removal of the BAS mapping was
intentional, reset sensors through the menu.

fault that it cannot recover.
Order replacement units and return the affected
devices to Johnson Controls under the RMA
