Sanden Heat Pump Error Codes G3 GS3-45HPA-AU
Description
Sanden Heat Pump G3 GS3-45HPA-AU Error Codes
This is an excerpt from the PDF Sanden Heat Pump - Service Technical Manual Pages 33 - 50 for the error code summary for the Sanden Heat Pump G3 GS3-45HPA-AU.
"When an error has occurred, a red LED on the operation panel turns on and an error code is displayed on the LED display. The panel does not revert to the display sleep mode while the error code is shown.
After a component is replaced or the inspection is completed, turn the breaker OFF for a period of 3 minutes before restarting to confirm the error does not re-occur. Below is the list of the error codes. If the corrective action does not solve the error problem, a malfunction of the PCB is highly likely."
