You may have heard people talking about Air Conditioning Zoning or Zoned Ducted Air Conditioning and wondered what it is and how it works. Firstly, it pays to know the basics about what air conditioning is and specifically about ducted air conditioning. Next step is to explore the world of zoned air conditioning systems.

You may be in the market to purchase a new home air conditioner and what to know if an air conditioning zone controller would be good option for you. Alternatively, you may already have an existing AC system and are looking at adding zones to the ducted air conditioning.

You could also be in the planning stage of a commercial HVAC installation, and looking into a zoned air conditioning system for the building. The need for zoning will largely depend on business activity and layout of the workspace/s.

Whatever questions and curiosities you may have about air conditioning zoning, we hope to provide some basic information to help inform and guide any decision-making process.

What is Air Conditioning Zoning?

Air conditioning zoning involves to the division of a building into separate areas (i.e. zones). Each zone will then have some degree of individual climate control. This may include on/off, airflow, and/or temperature.

AC zoning can occur in a home, business, or any other enclosed structure. It is typically incorporated with a ducted air conditioner, although it can be part of a central air conditioning system with some limitations.

Having an air conditioning zone controller installed increases comfort to the occupants of the building. It also increases energy efficiency of the air conditioning system it is connected to.

There are a wide range of multi zone air conditioner options on the market, with pros and cons for each one. iZone, MyAir, AirTouch, ZoneMaster, and Siemens Control Systems are some common zoning systems on the market.

Some individual air conditioning brands also provide zone control options. Examples include Daikin Zone Controller, Fujitsu Zone Control Interface, or Brivis Zone Plus.

The range of features available with ducted zoning systems is extensive. Touch screen displays, individual temperature sensors, timers, motion sensors, Wi-Fi and integration with smart home systems are just some of the options. Added features typically comes with additional cost. However, some of the added features can help you save money in the long term.

How to Zone Air Conditioning

There are many ways to zone air conditioning based on the building itself, layout, usage, specific requirements, and personal preferences. Just like selection of an air conditioner brand, the zoning system brand and associated wall controller require careful consideration to find the best option for you.

Daikin Basic Zone Control and AirHub

Daikin offers both simple push-button zoning and the more advanced AirHub Touch Zone Controller for compatible Daikin ducted air conditioning systems.

Daikin Basic or Push Button Zone Control

This straightforward option provides individual on/off control for each configured zone. It is a practical choice when app control and individual room temperature adjustment are not required.

Daikin AirHub Touch Zone Controller

Daikin AirHub is available in 4- and 8-zone configurations with a 7-inch colour touchscreen. The On/Off version switches individual zones on or off. The Individual Room Control (Linear) version can also adjust each zone within ±2°C of the main set temperature using OptiZone airflow control.

Key features:

4- or 8-zone configurations.
7-inch colour touchscreen.
On/Off or Individual Room Control (Linear) variants.
OptiZone airflow control with the Linear variant.
Each Linear-control zone requires its own compatible wired or wireless temperature sensor; one sensor cannot be shared across multiple zones.
Weekly scheduling and energy-management settings.
Compatible Airbase equipment can add app-based remote control, subject to the selected system configuration.

Available features and compatibility depend on the exact Daikin ducted system, controller and sensors selected. Ice Blast will confirm the suitable combination for your installation. For current product information, see Daikin’s AirHub Touch Zone Controller information.

Individual Room Sensors

Individual room sensors measure the temperature in each zone, helping a compatible zoning system adjust airflow in response to conditions in that room. This can improve comfort where bedrooms, living areas or rooms with different sun exposure warm up and cool down at different rates.

For customers wanting individual room control, we recommend discussing Daikin AirHub with compatible room sensors as part of the ducted system design. Sensors are additional components and must be specified in your quote. The AirHub Linear configuration requires a separate compatible sensor for every zone it controls.

Siemens Zone Controller

Siemens control systems range from full-scale commercial building automation and HVAC control, down to basic home air conditioner zoning control.

On the larger scale, Siemens offers Desigo (large scale building control), Synco (small-medium building control) and GAMMA (multi-faceted smart control) as some of the best HVAC zoning systems on the market.

On the smaller scale, Siemens offer innovative residential zoning solutions for standard ducted air conditioning systems.

Air conditioning zoning is a more energy efficient and controllable method of heating or cooling a home, workplace or other indoor space compared to zoneless AC systems. Gone are the days that the whole system has to be on or off, with no variation in between.

There is a large range of air conditioning zone controllers on the market, with features specific to each brand and price point. We have highlighted some of the popular choices, but there are still many more available.

Research is valuable when looking to invest in zone control or a new zoned ducted heating and cooling system. This includes speaking with experts in the field and working with them to find a suitable option for you.
