Brivis Fault Code 45

Brivis Error Code 45 Low 24Vac: The 24Vac voltage level has dropped below the threshold level defined by factory parameter number 27 for at least the 24Vac under threshold level time.

For Heater Repair Tech Only

Reason: The 24 volt circuit has been subjected to low voltage, resulting in insufficient 24 Volt output for reliable ignition or operation. This low voltage condition is usually only temporary and may be the result of a power loss or brown out. Service Check List: • Check incoming power supply voltage (minimum 200 V). • Check if power supply is not from a generator (may not be 50 Hz or might be wave rectified). • Check if the 2 Amp fuse blown. • Check the transformers secondary voltage output is within specifications. • If the Network 506 is connected, check the current output on terminals 24 V and GND does not exceed 0.3 Amp’s. Transformer Voltage 2.25A Transformer Nominal Voltage/ Maximum Current 230 VAC / 2.25 A Secondary Voltage (No Load) (Red – Black) @ 230 VAC 13.87 – 15.33 VAC Secondary Voltage (No Load) (Black – Yellow) @ 230 VAC 12.07 – 13.34 VAC Secondary Voltage (No Load) (Red – Yellow) @ 230 VAC 25.94 – 28.67 VAC
