Toshiba Fault Codes
On split A/C equipment it signifies an indoor to outdoor communication failure.
On VRF equipment it could also be attributed to communication breakdown between condenser PCB's.
Likely causes:
- Indoor PCB.
- Condenser PCB.
- Interconnecting Wiring.
- Fault with the transformer used to power condenser PCB.
2 Pipe VRF & Split A/C equipment High Pressure switch activation 425psi-29bar.
3 Pipe VRF equipment, interrogate condenser PCB for additional fault code.
Detected at outdoor.
Likely causes:
Split A/C equipment faulty H.P. switch, restriction in refrigerant flow, fan motor failure, poor airflows.
VRF equipment, set condenser interface PCB switches as follows SW1 @ position 2 & SW2 @ position 0 (see sub codes Er21 or ErAd)
