*Code is reported by the thermostat
**Fault indicates a system error and will typically clear in 5 minutes
***Malfunction indicates repetitive occurrence of a Fault and may indicate a more serious problem. Most Malfunctions will inhibit system operation until shutdown
condition clears or for a period of 4 hours.
