12.1.2 System Operation Concept
The control function is divided between indoor and outdoor unit controllers. Outdoor unit is the system
‘Master’, requesting the indoor unit for cooling/heating capacity supply. The indoor unit is the system
‘Slave’ and it must supply the required capacity unless it enters into a protection mode avoiding it from
supplying the requested capacity.
Target frequency is transferred via indoor to outdoor communication, and the calculation is based on
room temperature and set point temperature.
