17.3 Error Codes
Below are shown the error codes which will be displayed on the THINK Controller if a fault occurs on the appliance. Error Codes shown on remote interfaces may be collective
codes refer to the THINK Controller for the exact error message. More than one error may be present so that subsequent error codes will be shown as the original error is reset.
The occurrence of an error code will prevent some or all of the operations of the appliance.
Error codes specific to the running of the engine will not prevent the supplementary burner from operating and visa verse.
There are three levels of error code with associated reset procedures as follows:
1. Automatic reset (AR) Examples are mainly to do with temperature sensing but also include monitoring of the mains supply. Automatic reset only occurs if the fault
condition is eliminated.
2. User reset (UR) An example would be the restoration of the gas supply to enable ignition.
3. Service reset (SR) arises when a reset of the condition needs to be accompanied by the attendance of a service engineer.
There are two special conditions:
1. Automatic reset after power down (ARP) an automatic reset can only occur after the electrical supply is interrupted. Usually this implies data corruption and is in effect
a 'reboot' of the PCB.
2. No restart possible (NRP) occurs if there is corruption of stored data for instance and implies that the PCB will have to be replaced.
