Daikin

d0

Lockout

Data not yet on network

Communicating pair is wired and the IFC has no shared data (new board, missing memory card, learn not done).

Walk d0 in Diagnose

4 plates — walk the one on the cabinet

First check

1 Read the plug / card on THIS cabinet

On Daikin DM80VC the model plug or shared-data card must match this cabinet size. A 100 kBtu plug in an 80 cabinet overfires and limits. A leftover memory card after a control swap throws d0/d4-class codes. Memory card / ComfortBridge learn for this SKU.

Expect: Plug / card part matches the rating plate and the replacement control bulletin.

The rest of the walkthrough is Diagnose.

On the plates

  • Memory card / ComfortBridge learn for this SKU.
  • Outdoor and Daikin One actually on the bus? d0 on a standalone 24V job means someone enabled communicating when the network is empty.
  • Do not confuse with E0 (ignition lockout).
  • Memory card / learn. Empty network if someone landed data wires with no Daikin One / outdoor.

Plates that use d0

Same number, other makers

d0 on Daikin is not the same code on these plates.
