Equipment is unable to communicate. Indicates numerous message errors. In most cases errors are related to electrical noise. Make sure high voltage power is separated from BUS. Check for miswired and/or loose connections between the stat, indoor unit and outdoor unit. Check for a high voltage source of noise close to the system. Fault clears after communication is restored.
The outdoor control has lost communication with either the thermostat or indoor unit.

Air handler (indoor)
This manual entry does not list further causes or actions.
Equipment is unable to communicate. Indicates numerous message errors. In most cases errors are related to electrical noise.
Models: CBK48MVT
Equipment is unable to communicate. This may indicate the existence of other alarms / codes. In most cases errors are related to electrical noise. Make sure high voltage power is separated from BUS. Check for mis-wired and/or loose connections be- tween the thermostat, indoor unit and outdoor unit. Check for a high voltage source of noise close to the system. Generally, this is a self-recoverable error.
The air-handler has lost communication with the rest of the system.
