Why is heating ineffective on my Johnson Controls Controller?
If heating is ineffective on your Johnson Controls Controller, it means the Supply Air Temperature has not increased above the configured Supply Air Temperature Alarm Offset while heating has been active for at least the Supply Air Temperature Alarm Delay. Verify that the heating elements on the rooftop are functioning properly.
Why is cooling ineffective on my Johnson Controls Controller?
If cooling is ineffective on your Johnson Controls Controller, it means the Supply Air Temperature has not decreased below the configured Supply Air Temperature Alarm Offset while cooling has been active for at least the Supply Air Temperature Alarm Delay. Verify that the cooling elements on the rooftop are functioning properly.
What to do if my Johnson Controls Controller displays Supply Fan Fault?
If your Johnson Controls Controller displays 'Supply Fan Fault', it means the Supply Fan Status configured for either BI1 or BI2 has not proved within the configured Fan Alarm Delay. To troubleshoot this: 1. Verify that the Supply Fan is operating when turned on. 2. Verify that the Supply Fan Status wiring is connected correctly.
What to do if my Johnson Controls Controller displays Zone Temperature Too Cold?
If your Johnson Controls Controller displays 'Zone Temperature Too Cold', it means the Zone Temperature has decreased below the configured Zone Temp Low Limit. Verify that the TEC and the RTU heating are enabled and functioning.
What to do if my Johnson Controls Controller displays Zone Temperature Too Hot?
If your Johnson Controls Controller displays 'Zone Temperature Too Hot', it means the Zone Temperature has increased above the configured Zone Temp High Limit. Verify that the TEC and the RTU cooling are enabled and functioning.
Why does my Johnson Controls Controller display Idle with Cooling/Heating Unavailable due to Changeover?
If your Johnson Controls Controller displays 'Idle' with a Unit Status of 'Cooling Unavailable due to Changeover' (despite being above the cooling setpoint) or 'Heating Unavailable due to Changeover' (despite being below the setpoint), it indicates that the two-pipe fan coil/VAV system does not have a changeover sensor and switch connected, or the sensor/switch has failed. To resolve this: 1. Check the wiring of the supply temperature sensor/switch. 2. Verify that the changeover is set up correctly for the type of sensor attached (sensor or switch).
