Fixing on demand function (dE)
Press “PSW1” and select the setting condition “1”, so that the xing of demand function “dE” can be set.
However, it is not necessary to short-circuit the demand input terminals on the outdoor unit PCB. (Refer to section “6.1.4
Descriptionofoptionalsignals”in the input “e.Currentcontroldemand(5/6/7/8/9/10)”)
