Brivis Error Code 63 Primary Valve Fail: During Heating, the primary valve control relay is not detected as closed.
For Heater Repair Tech Only
Reason: While the primary valve control relay should be energised its contact is detected as opened by the primary microcontroller Once the state is entered the primary valve control relay contact state is continuously monitored by the primary microcontroller until the “OFF” state of the heating cycle is entered If the primary valve control relay contact is unexpectedly detected as opened by the primary microcontroller a lockout condition (Code#63) is registered by the primary microcontroller forcing the heating cycle into the “OFF” state. Service Check List: If Error 63 has occurred in the past on this heater then replace the NG-2 Module For a first time Error 63 reset NG-2 Module then retry heater operation. If NG-2 cannot be reset or if Error 63 reoccurs then replace NG-2 module and retest.
