What to check if Johnson Controls TEC3011 says Zone Temperature Too Hot?
If your Johnson Controls Controller reports that the zone temperature is too hot, it means the zone temperature has exceeded the configured Zone Temp High Limit. You should verify that the TEC and the RTU cooling are enabled and working properly.
What should I do if my Johnson Controls TEC3011 displays Zone Temp Unreliable?
If your Johnson Controls Controller displays 'Zone Temp Unreliable,' it means all sources of zone temperature, including the onboard sensor, are unreliable. The suggested solution is to order replacement units and return the affected devices to Johnson Controls under the RMA program.
Why does my Johnson Controls TEC3011 say 'Cooling Unavailable due to Control Mode' or 'Heating Unavailable due to Control Mode'?
If your Johnson Controls Controller displays 'Idle' with a unit status of 'Cooling Unavailable due to Control Mode' (even when above the cooling setpoint) or 'Heating Unavailable due to Control Mode' (even when below the heating setpoint), it indicates that the control mode setting is incorrect. Here’s what you should do: * If the Control Mode is set to 'Cooling Mode' but the controller is requesting heating, change the Control Mode to 'Auto' or 'Heating'. * If the Control Mode is set to 'Heating Mode' but the controller is requesting cooling, change the Control Mode to 'Auto' or 'Cooling'.
Why does my Johnson Controls staged equipment shut off prematurely when the PID is running?
If your staged equipment shuts off above the cooling setpoint or below the heating setpoint when the PID is running on the TEC, it is expected behavior. The PID control algorithm minimizes overshoot and energy usage, which may cause the equipment to cycle before reaching the setpoint.
Why does my Johnson Controls heat pump heat when it should cool, and cool when it should heat?
If your heat pump heats when it should be cooling, and cools when it should be heating, it indicates that the reversing valve polarity is set incorrectly. To fix this, consult the equipment documentation to verify the correct reversing valve polarity, and then adjust the Reversing Valve Polarity menu option accordingly.
What should I do if my Johnson Controls Controller displays Controller Fault?
If your Johnson Controls Controller displays 'Controller Fault', it means an internal fault was detected and the controller was unable to recover. Order replacement units and return the affected devices to Johnson Controls under the RMA program.
What does Supervisory Status = Offline mean on my Johnson Controls Controller?
If your Johnson Controls Controller displays 'Supervisory Status = Offline', it indicates that the supervisory controller isn't communicating with the TEC, the TEC isn't mapped to a JCI Supervisory System, or the WNC Gateway isn't communicating with the TEC. To resolve this: 1. Map the TEC into a JCI Supervisory system. 2. Verify that the PAN’s WNC Gateway is online. 3. Add ZFR Pro Routers/Repeaters into the wireless system.
Why are OA Lockouts Disabled on my Johnson Controls TEC3011 Controller?
If OA Lockouts are disabled on your Johnson Controls Controller, it means the local outdoor air temperature sensor has become disconnected or failed, or a network outdoor air temperature sensor has timed out. As a result, the controller is no longer shutting down equipment based on the OA lockout setpoints. Here's what to do: 1. If the outdoor air temperature source was a locally connected sensor, follow the troubleshooting steps for the Outdoor Temp Fail alarm. 2. If the outdoor air temperature source was a BAS, check the BAS to ensure it's online and providing the TEC with temperature readings. If you intentionally removed the BAS mapping, reset sensors through the menu.
Why is the Econ Unavailable on my Johnson Controls TEC3011?
If your Johnson Controls Controller displays 'Econ Unavailable', it means the outdoor air temperature sensor is either not installed, has failed, or has been disconnected, preventing the controller from managing the economizer. To fix this, follow the same steps as for an Outdoor Temp Fail alarm: * Check the wiring of the sensor. * If intentionally disconnected, reset sensors through the menu. * If problems persist, order replacement units and return the affected devices to Johnson Controls under the RMA program.
How do I troubleshoot a Supply Temp Fail error on my Johnson Controls Controller?
A 'Supply Temp Fail' error on your Johnson Controls Controller means that the external supply temperature sensor is either disconnected or has failed. Here’s how you can troubleshoot it: 1. Check the wiring of the sensor to ensure it is properly connected. 2. If the sensor was intentionally disconnected, reset the sensors through the menu. 3. If the problem continues, order replacement units and return the affected devices to Johnson Controls under the RMA program.
