Daikin

idle / Ht1 / Ht2 / CF

Status

Status, not a fault

Ready, low heat, high heat, or continuous-fan CFM on the triple display.

Walk idle / Ht1 / Ht2 / CF in Diagnose

3 plates — walk the one on the cabinet

First check

1 Confirm this is not a fault

On the Daikin DM80VC this readout (idle / Ht1 / Ht2 / CF) is run status, not a lockout. Write what the display actually shows and whether W/Y/G is present at the IFC.

Expect: Idle / Ht / CF / stage+CFM words change when you apply and remove the call.

If fail: If the word never changes on a real call, the call is not reaching this IFC.

If pass: The board is alive. Diagnose the comfort complaint, not this code.

The rest of the walkthrough is Diagnose.

On the plates

  • Do not change the board because it says Ht1 or CF.
  • CF is continuous fan, not a capacitor.
  • Ht1 forever with a high-stage request → E9 / staging, not a bad status word.
