SETTING OF SLAVE UNIT When using the remote control switch (PC-AR(T)), the half-size remote control switch (PC-ARH) or receiver kit (PC-ALH∗), after the setting of master unit, the central station automatically set the slave unit. Check for the setting state by the slave unit setting mode. 4.3.1.
GROUP SETTING b. Select the refrigerant system address and indoor unit address to set. The refrigerant system address is changed by depressing ∇ " " (TEMP) switch and the indoor unit address is changed by depressing "Δ" (TEMP) switch in order as shown below. In this case, the switch is kept depressing, and the indication of the refrigerant system address or the indoor unit address is fast-...
GROUP SETTING 4.3.3. CANCELLATION OF SLAVE UNIT SETTING a. Screen Change for Cancellation of Slave Unit Setting. Keep depressing the "CHECK" switch for 3 seconds during all the indoor unit is stopped (with "RUN" indicator OFF). The "CHECK" indicator turns ON, and it shows the state is changed to the CHECK mode.
