Cold Start Cold Start
Warm Start Warm Start
If the auto-tuning begins near the set point ( warm start ), the unit passes the
warm-up cycle and enters the waiting cycle. Afterward the procedures are
same as that described for cold start. If the auto-tuning begins near the set point ( warm start ), the unit passes the
warm-up cycle and enters the waiting cycle. Afterward the procedures are
same as that described for cold start.

1. Try auto-tuning once again.
2. Don't change set point value during auto-tuning procedure.
3. Don't change event input state during auto-tuning procedure.
4. Use manual tuning instead of auto-tuning. ( See section 3-20 ).
5. Touch any key to reset
