More than one ducted system on a floor plan

A big house, a home with a separate living wing or a two-storey home with one unit per level can now be designed as more than one ducted system on one floor plan. Each system has its own indoor and outdoor unit, its own zones and its own price. The quote gets one area per system.

How it works

• Add a system. Drop a second indoor unit and click Add system, or add one on the Systems & zones tab. Up to 4 per plan.
• Lay out its ducts. Draw from the new unit, or run Auto Layout to lay out every system at once.
• Zone each system on the Systems & zones tab, which replaces Zones.
• Colour by system. The Parts tab shows each system's parts in its own colour.
• Price it. Recommendations prices every system for one tier and shows the total.

Before you quote

If something would stop the plan pricing correctly, a Before you quote list shows when you generate options or create the quote. Click a line to go straight to the room or part. Fix buttons such as Run Auto Layout and Split into systems sort most of them in one click.

Plans you already have

• Nothing changes when you open them.
• A plan with 2 indoor units on one level offers Split into systems.
• Old "one per level" plans become one system per level at the next Generate Recommendations or Auto Layout, at the same prices.
• The layout mode choice is gone. A two-storey home starts as one system with droppers. Start with one per level splits it by level in one click. Over 25 kW, a hint suggests it.
• Recommendations warns when a unit is more than 0.5 kW below its load.

A sizing change to know about

On a plan with more than one level, each room is now sized at its own level's ceiling height, as the Heatload step already shows. Where the heights differ, your next Generate can recommend a different size at a different price. Opening a plan or a saved quote never changes its price.

Also new on the floor plan

• Notes on ducted, VRV, ventilation and subfloor plans now take five colours, line breaks and an arrow with a choice of Arrow end.
• The pipe drop counts. Set Mounted on for a ducted outdoor unit. The pipe total now adds the drop, single storey included. The label shows it: Refrigerant 15.2 m + 2.7 m drop. It counts toward pipe over 20 m.
• Up to 5 floors with basements on VRV, ventilation and Measure Quote plans. Ducted plans take 2 storeys above ground plus 1 basement, which gets its own system.
• Show level below overlays the level under the one you're on.
