What's the size of the area to be conditioned?
Only count the rooms you want air-conditioned — skip bathrooms, garages and laundry.
Is this a new install or a replacement?
Zones let you open/close airflow to different parts of the home. Most Sydney homes use 3–6.
Most homes only run a few zones at a time — we size the unit to match actual use, not every zone on full.
Zone controllers let you manage each zone independently from a wall panel. WiFi add-on also lets you run the system from your phone.
