• Peak cut operation
Reduces the power consumption by setting a specific target value (maximum average power [kW])
for all the air conditioners and controlling operation so that this value is not exceeded.
Limit control is performed in 3 steps of “Step 1: Set temperature shift” → “Step 2: Thermostat OFF”
→ “Step 3: Outdoor unit stop”.
To perform this control, an electricity meter must be installed.
