Why doesn't the TEC3000 Johnson Controls Thermostat zone temperature change fast enough?
If the TEC3000 zone temperature on your Johnson Controls Thermostat does not change fast enough compared to the measured zone temperature from a verification device, it means 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 temperature change too much in unoccupied mode on my Johnson Controls Thermostat?
If the zone space temperature increases or decreases too much when the unit is active in unoccupied mode on your Johnson Controls Thermostat, it means 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.
What to do if my Johnson Controls Controller displays Open Window?
If your Johnson Controls Controller displays 'Open Window', the switch connected to the BI configured for Open Window is sensing that the window is opened, and control has shut down. To address this: 1. Close the window to resume control. 2. Check sensor functionality with an ohmmeter, and verify the wiring to the TEC. 3. Order replacement units and return the affected devices to Johnson Controls under the RMA program.
What to do if Johnson Controls Controller shows 'Internal Sensor Fail'?
Order replacement units and return the affected devices to Johnson Controls under the RMA program. This is due to an internal sensor failure on the TEC.
What does 'Zone Temp Unreliable' mean on my Johnson Controls Controller?
If your Johnson Controls Controller displays 'Zone Temp Unreliable', it means all sources of zone temperature, including the onboard sensor, are unreliable. You will need to order replacement units and return the affected devices to Johnson Controls under the RMA program.
What to do if the Johnson Controls Fan displays 'Zone Temp Unreliable'?
If your Johnson Controls Fan displays 'Zone Temp Unreliable,' it means all sources of zone temperature, including the onboard sensor, are unreliable. Order replacement units and return the affected devices to Johnson Controls under the RMA program.
Why is the temperature displayed lower than actual on Johnson Controls Controller?
If the Johnson Controls Controller displays 'The temperature displayed is lower than the actual room temperature', seal any holes behind the TEC to reduce drafts. If air is 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. This issue can happen because cold air drafts enter the back of the TEC, or air is being forced through the TEC from a nearby vent.
How to fix rapid cycling with PID on my Johnson Controls Thermostat?
If the staged equipment cycles too rapidly or slowly on your Johnson Controls Thermostat when the PID is running, it may be due to the control band around the setpoint being set incorrectly. Verify that the equipment's minimum on/off times are set correctly. If the default deadband doesn't provide the required temperature control, set 'Temp Control Setup' to 'Deadband Override' and adjust the 'Deadband' parameter to your preferred value.
How to resolve a firmware mismatch on my Johnson Controls TEC3000?
To resolve a 'Firmware Mismatch' on your Johnson Controls Thermostat: First, upgrade the TEC3000 to the latest released version. Then, upgrade the TEC3000 to the current version again. If the previous downgrade has not completed because the previous version is no longer supported, reboot the TEC3000 to clear the fault.
What does Board Mismatch mean on my Johnson Controls Thermostat?
If your Johnson Controls Thermostat displays 'Board Mismatch', match the baseboard to its corresponding CPU board.
