6.2 On demand control (Local wiring)
By performing the following modifi cation, energy consumption can be reduced to 0–100% of the normal consumption.
The demand function will be activated when a commercially available timer or the contact input of an ON / OFF switch is added
to
the CNDM connector (option) on the control board of the outdoor unit.
Complete the circuit as shown when using the external input adapter (PAC-SC36NA). (Option)
By setting SW7-1 on the control board of the outdoor unit, the energy consumption (compared to the normal consumption)
can be limited as shown below.
