3. To carry out operation mode switching and demand control simultaneously
You can carry out operation mode switching and demand control simultaneously by setting
function switch SS1 on the adaptor to "BOTH." Only one address, however, can be set on the
adaptor, so the "operation mode switch unit" and "demand control unit" are the same.
Set the COOL/HEAT address, demand address and low noise address, or both as needed.
Note 2: The outdoor unit can have an independent "COOL/HEAT address" and "demand
address". You can therefore set the "operation mode group" and "demand control
group" to different ranges.
Factory set to "BOTH".
