1. Connecting your VAV12 System

1.1 Compatibility

A User Interface (UI) has been developed to simplify the commissioning, use and change of operating

parameters for the SAI HVAC range of products. A click of “Other Systems” at the top of the user page switches

between the various SAI HVAC systems.

1.2 Simple and Upgradable

The VAV12 architecture allows for remote upgrade of many features so as development continues new

features can be added via an internet connection.

1.3 Plug & Play

You can also add one of the other SAI HVAC systems such as climate control and lighting control. SAI HVAC

systems are “plug and play” you don’t need to call in a programmer, automation specialist or specialist

technician. Once the systems are connected on the same LAN they recognise each other and the appropriate

interface is loaded without the need for you to do anything.

1.4 Html User Interface

The html user interface can be used on most devices with a browser from Smartphone or tablet to PC. The

display results vary slightly depending on your device and browser type used. Many people choose the iPad

mini as their UI platform but a laptop, PC or even your iPhone/Samsung can be used to control your SAI HVAC

product. Now, you’ll likely not use your phone or tablet often to turn lights on and off, after all you have

switches in all the normal places, but when you want to change a time clock setting on your perimeter security

lights or change a group setting, even set multiple dimming levels to create the mood you want for a special

occasion, the User Interface is fast, easy and convenient.

1.5 Remote Access

Providing your system is connected to a Local Area Network (LAN) with an internet connection, System allows

you to remotely access your SAI HVAC systems remotely. This feature can be convenient for many reasons and

is achieved by a secure connection through the SAI HVAC Mothership (MS) global server. You first login to

mothership and then browse to your various SAI HVAC devices connected to your mothership account. Your

mothership account can provide access to your SAI HVAC devices at multiple locations so if you are a building

manager you can have access to all your sites at your fingertips through this one convenient and simple access

point.

“chatterbox”

2. How to Connect to your System

There are three different methods for connecting to your system. The method you choose will depend on your

location and the type of installation you have in your building. Although you can connect to the inbuilt Wi-Fi

(see 2.1) a LAN connection is RECOMMENDED for optimal performance (see 2.2)

2.1 Direct Connection via Wi-Fi

NOTE: The service Wi-Fi is for use when commissioning your system and only when no LAN connection is

available. Some warranty terms are affected when connecting using this Wifi service solution.

Each VAV12 controls system can create its own network via Wi-Fi. This means you can connect your smart

device/computer to the system.

1. Open your Wi-Fi settings on your device and select the SAI VAV network (Figure 1)

2. The Password is “chatterbox”(Figure 2)

3. Once connected to the controls network you can open your browser and browse to the system IP

address 192.168.2.11

4. You may wish to bookmark the page or add a link to your home screen on your device, so that you

can press the link instead of having to refer back to the IP address each time you wish to connect.

(Figure 5)

5. Direct connection requires your personal device/PC to be within range of the controls network. As

this range can vary significantly depending on building conditions, the preferred method of

connection is via a LAN as discussed in the following paragraph.

Figure5 –User Interface launches

2.2 Direct Connection via your LAN

Connecting your system to your local LAN via a network cable connected from your VAV12 MPM module to

your router or a switch connected to your router is the preferred and best method for regular connection. You

can then access your system from anywhere you have LAN coverage. (Figure 6)

When a connection is made your router will assign a unique IP address to the system. You can find this IP by

checking in your router settings but we recommend you download one of the free programs for your apple of

android device such as FING (Figure 7). Such programs search your LAN and list all connected devices. This will

enable you to find your system IP, typically look something like 192.168.1.12 or similar number (Figure 8). By

typing this number into your browser you will be able to access the Opening page of your system.

NOTE: Some routers ship with UPNP disabled. You should check your router instruction manual for details on

how to check this setting. Without UPNP enabled, the system cannot connect. Remember that after power

failure your router may assign a different IP number to your system. In this case you will need to scan your

network with FING or similar program to find the new IP. It is possible to set a fixed IP in your router settings

however the method varies depending on your router brand and model. Your IT specialist should be able to

help. Connecting your system to your router using a cable gives a level of access control as access can only be

achieved by persons or devices having your LAN access password.

2.3 Connection via Mothership (Recommended)

Providing your system is connected to your building LAN and that your LAN has an internet connection, you

can setup an account on the SAI Mothership global server to allow remote connection to your system via MS.

1. Open your browser and browse to https://chatterboxmothership.com.au and click the register

button on the login page. (Figure 9)

2. Fill out your registration details and we will send you your registration name and password within

24 hours together with instructions on how to access your system via the Mothership.

3. If you are within the LAN, i.e. at home and your device is connected to the same network the

system is running on, there will be a link at the bottom of the log in page titled “Your Local Devices”

with the Mac Address and system description. You can click this link to go straight to the User

Interface without having to log in. (Figure 9)

4. Once you have received notice of your User Name and Password, go to the log in page, enter the

details, then press Login.

5. The next screen that launches will have a list of your systems. (Figure 10)

6. To access the User interface for any of your systems press the Launch button on the right hand

side. This will launch the interface and you can start to control your device. (Figure 11)

2.4 Using the Mothership Cloud Service

3. VAV12 Operating Instructions Using the User Interface

1. Open the User interface using the steps mentioned in 2.1, 2.2 or 2.3

2. The page will open in the “Overview Screen”. (Figure 14)

3. The overview screen is where you change all system wide values.

3.1 Changing the System Mode

Press the Auto, Heat, Cool or Vent Buttons. (Figure 14 –Yellow Arrow)

3.2 Notes on Dynamic Energy Recovery

Your SAI HVAC multi zone temperature control system modulates its output capacity to match the heat load. It

continues to cool or heat individual zones until they reach the target temperature (set point). When all zones

are at target temperature, the refrigeration cycle is switched off. On a system where dynamic energy recovery

is disabled, any room can re-activate cooling or heating when the temperature moves away from set point by

0.5°C. Dynamic energy recovery is a technology designed for structures that include a large central area

surrounded by perimeter rooms. The perimeter rooms lose and gain heat at a much faster rate than the

central area. The reason for this phenomenon is that the portion of external walls and roof to room volume is

significantly higher and the additional thermal mass of the central area reduces the rate at which heat is

gained or lost. The dynamic energy recovery algorithm intervenes when a perimeter zone calls for heating or

cooling, it then measures the return air temperature (positioned din the large central zone) to apply a

proprietary algorithm that calculates the flow needed to slow down the rate at which heat is gained or lost.

The slider allows the user to find the right balance for their home or building between energy reduction and

comfort. The slider moves the point at which the worst performing zone can terminate dynamic energy

recovery and force heating or cooling.

The VAV12 zoning control is a unique part of the SAI HVAC system that provides the ability to dramatically

reduce your energy bills. It is important to note that the average household uses 38% of their power bill on

heating and cooling. It is also important to note that every degree Celsius difference between the inside

temperature and the outside temperature adds 10% to the energy cost for that room. SAI HVAC’s multi zone

temperature control system automatically adjusts the airflow to individual rooms to make sure that cooling

and heating overshot is eliminated. There are 3 additional energy settings that are use adjustable that

decrease energy use further. This feature is most often used in combination with occupancy sensors. When

applied in this fashion you can move through your home & the system automatically turns on and off as

required.

3.3 Set the Optional Countdown Timer

Slide the “Auto Off” slider to the desired position between 30 & 240 minutes. The Auto Off timer is only used if

you wish the system to run for that period of time and then switch off. The system then requires a re-start.

This feature is designed as a safe guard for properties where the air conditioning can be left on while not

required. (Figure 14 –Red Arrow). Anytime there is an on event on the system in any zone, the system will

continue to operate. This feature is most often used in combination with occupancy sensors. When applied in

this fashion you can move through your home & the system automatically turns on and off as required.

3.4 Optional “Cooling” and “Economy” settings

See figure 14 (blue arrows), use the slider bar to change.

Figure 15 –Global Time schedules page is launched. Set on/off events for the whole system from the Overview page or individual events

can be set from the home page.

brochure.

3.5 Setting the Global Time Schedules

Ensure the “Global Time Schedules” button is “ON” (Figure 14 –Purple Arrow). The Global Time Schedules

button is handy if you are going to be away from the property for a period of time (i.e. holidays). You can

toggle this button to “OFF” and it will not activate your time clock events while you are away. When you return

home, you can simply toggle the button to “ON” and your previously set timeclock events will resume as

before. To access the Global Time Schedules page Press the “HIDE SHOW” show button in the bottom right

hand corner (Figure 14 Green Arrow). This will launch the Global Time Schedules screen (Figure 15).

Setting Global Time Schedules cont… Press on any day in “Schedule A” you wish to activate and the day will

illuminate Green (Figure 15 –Yellow Arrow). Use the drop down bars to set on and off time for the system

(Figure 15 –Red Arrow). Repeat these steps for “Schedule B”. It is important to note that these settings when

launched from the Overview page will activate On/Off events for the whole system (every zone). To set

individual zone timers please see below point 4.11

Figure 14 - User Interface opens in the “OverView Screen”. Set the mode (Yellow Arrow). Set the optional Countdown timer (Red Arrow). Set the Optional

Cooling and Heating Comfort / Economy sliders (Blue Arrows). Turn on the Global Time Schedules button (Purple Arrow). Press the “Hide Show” button to

enter the global time schedules screen (Green Arrow)

3.6 Leaving Global Time Schedules Page

Press the “Hide Show” button at the top right of the page and this will take you back in to the Overview

Screen. (Figure 15 –Blue Arrow)

3.7 Accessing Individual Zone

Press on the Select Zone Button. This will drop down a list of the zones in your home or premises (Figure 15 –

Purple Arrow). Then press on the zone name you wish to access and it will launch the User Interface page for

that zone. (Figure 15 - Green Arrow)

3.8 Return to Overview page

Press the overview button.

3.9 Browse to Other Systems

If you have multiple SAI HVAC Air Conditioning or Lighting systems, use the “Other Systems” button to browse

to them. Simply select the system you wish to interact with from the drop down list.

3.10 Adjusting the Settings on a Zone

Use the slider bar to adjust the temperature set point within the zone (Figure 16 –Yellow Arrow). To use the

system most efficiently, we recommend a set point between 20 and 24 degrees for each zone and the zone to

be left in “Temperature Control” mode. To change the mode to “Airflow Control” (disables the temperature

sensor and delivers the maximum airflow specified for the zone at 100%) press on the “Airflow Control” button

(Figure 16 Red Arrow). In Airflow Control mode, you can use the slider bar to adjust the percentage of air being

delivered between 0-100%.

3.11 Setting Time Schedule for Individual Zones

Go to the zone and press the “HIDE SHOW” button in the bottom right hand corner (Figure 16 –Orange

Arrow). Then follow the same instructions as per points 4.5 and 4.6. Setting zone schedules will only action the

event in the zone you have selected.

Figure 16 –Adjust the Set point using the slider bar (Yellow Arrow). You can use the optional Airflow control feature by pressing the “Airflow Control
