Note (1) Factory setting – J13: Short-circuit, CnS2: Short-circuit (Short-circuit pin connected)
3)
The operation condition is desplayed on the LCD of remote controller and is transferred to optional centralised
controller.
4)
Demand control
Demand ratio can be switched with the dip switches (SW4-5, 4-6) on the outdoor PCB.
SW4-5, SW4-6 demand switching: 0 : Open, 1 : Short-circuit (Factory default is open)
