1.3 EEV Control

1) Superheating control (Cooling Mode)

- Superheating : T superheating = Tout – Tin = 2°C

- LEV pulse up : T superheating > 2°C

- LEV pulse down : T superheating < 2°C

2) Target Temperature Control (Cooling mode)

- In case, outdoor temperature > 39°C

- Target superheating : T target = Tin = 18°C

- LEV pulse up : T target < 18°C

- LEV pulse down : T target > 18°C

3) Target Temperature Control (Heating mode)

- LEV pulse up : T target > Tout

- LEV pulse down : T target < Tout

4) LEV pulse change Value

8 pulse (P1-P0 > 4°C)

4 pulse (4°C ≥P1-P0 > 3°C)

2 pulse (3°C ≥P1-P0 > 1°C)
