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 is the temperature displayed on my Johnson Controls TEC lower than the actual room temperature?
If the temperature displayed on your TEC is lower than the actual room temperature, it could be due to: * Cold air drafts entering the back of the TEC. Seal any holes behind the TEC to reduce drafts. * Air being forced through the TEC from a nearby vent. Move the location of the TEC or change the venting to prevent air from being forced through the TEC.
What does Supervisory Status = Offline mean on my Johnson Controls TEC3022 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 some icons hidden on my Johnson Controls TEC3022 Controller?
If some icons are hidden on your Johnson Controls Controller, it's because lockout levels are in use or the icons are hidden due to the display settings. See Table 5 for lockout levels and access details.
What does Controller Fault mean on Johnson Controls Controller?
If your Johnson Controls Controller displays 'Controller Fault', it means the controller has detected an internal fault that it cannot recover from, or an unknown error has prevented the controller from turning on. The suggested solution is to order replacement units and return the affected devices to Johnson Controls under the RMA program.
What to do if Johnson Controls TEC3022 provides an error when trying to upgrade firmware?
If your Johnson Controls Controller provides an error when trying to upgrade the firmware, it means the firmware on the USB drive is below the minimum required version (Error code 1025). Please use firmware version 2.0.2.xxxx or higher. A reboot is required to clear the Firmware Mismatch fault that occurs.
Why is my Johnson Controls TEC3022 unable to access a USB drive?
If your Johnson Controls Controller can't access a USB drive, it could be due to a couple of reasons: * The drive is formatted as NTFS or another unsupported format. The TEC supports FAT16 and FAT32 formats only. Reformat the USB drive, or try a different USB drive with a supported format. * The USB drive is defective. Try a different USB drive.
Why does my Johnson Controls staged equipment cycle too rapidly or slowly when the PID is running?
If your staged equipment cycles too rapidly or too slowly when the PID is running on the TEC, it's likely due to the control band around the setpoint being incorrectly set for the equipment, zone, or user preference. To adjust this: 1. Verify that the equipment's minimum on/off times are set correctly. 2. If the default deadband doesn't provide the desired temperature control, set 'Temp Control Setup' to 'Deadband Override' and adjust the 'Deadband' parameter to the desired value.
What should I do if my Johnson Controls TEC3022 Controller displays Board Mismatch?
If your Johnson Controls Controller displays 'Board Mismatch', it could be due to the following reasons: * The I/O board that the display board is currently attached to does not match the one that initially shipped with the display board. Attach the display board to the correct I/O board. * A hardware failure is causing the two boards to incorrectly identify themselves. Order replacement units and return the affected devices to Johnson Controls under the RMA program.
What should I do if my Johnson Controls TEC3022 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.
