Controller Placement

Many of the instructions and best practices for installing the Controller mirror the Monitor. 

Ensure the device is within WiFi range

Use a WiFi-enabled device like your phone to make sure the proposed mounting location of the Controller is within range of the home’s WiFi network. Open WiFi settings on your device to make sure it shows up in the list of detectable networks.

Installing the Controller between ducts or obstructed by other metal surfaces will reduce radio frequency performance. We recommend facing the Controller in the general direction of your router with little to no visible obstruction where possible. 

 

If you are adding the 3D printed tube to your installation, we recommend following the same principles to find the ideal RF location to identify the best mounting position on the air handler itself. The location needs to be on the blower case or door, and needs to provide enough space for you to use a drill and run the cable.

 

Wiring the Controller to HVAC Equipment

Please note: the Controller is only designed to switch loads under 30 volt with a 2 amp max current draw.

 

In this guide, we will discuss powering the Controller from the terminal on the central air system. The Controller could alternatively be powered by a 24VAC transformer instead.

 

If you’re adding an inline transformer or using the R and C terminals on the air handler, first turn off power to the air handler before making any modifications.

 

 

Powering the Controller

 

1. Prep your length of wire from the power source to the Controller, and leave length for a service loop. Since we're also controlling the G terminal of the air handler with this Controller, we will be running 2 pairs of wire - one for power and one for signal.

 

2. Remove the door and locate your power source, and do not energize the power until both sides of the circuit are connected.

    If you’re using a knockout hole or making a new hole for the wires, make sure you add a grommet or        cable gland to prevent air from escaping from the hole.

 

3. Strip back 2 inches from the cable jacket and one inch from the wire insulation to prep the connection to the power source.

    Here you can either use the Wago lever Nuts and splice in the Monitor power cable into the 24V                transformer low side, or if you’re planning to use the R and C for power, you can directly connect to          the terminals like you would a thermostat.

 

4. Insert the exposed wires into the power terminals on the bottom of the device. You can either use a small slotted screwdriver or the reset pin to depress the terminals to make it easier to connect the wires. 

    The power input is reversible, so don’t worry about which wire goes into which hole as long as they are      the color pair assigned to power.

Controlling HVAC Equipment

 

1. For controlling the blower, you need to add a wire to the G terminal and another wire to the R terminal. Remember which color pairs you’ve used for power and for control.

    The Wago nuts are especially useful if you have more than one device already connected to the                  control-board terminals, such as with the Monitor you’ve already installed     

    If you are only using 1 output on the Controller, please connect your signal wires to terminal 1. You            can add a second control circuit to terminal 2 if you are controlling 2 pieces of equipment with 1                Controller.

 

Make sure the wires are fully inserted by giving them a quick pull test.

Controller relationship to HVAC Equipment


Here's an example wiring scheme required to control the HVAC system's blower motor, via the Central Air Controller. 

CAC_Stuff_Thermostat_Wiring_2.png
In the above instance, Channel 1 of the Central Air Controller has been wired to control the AHU blower motor via the system's thermostat. Later on, we will set the controls to action our intended command. 

To control the blower in this manner, you'll need to run a wire to the G terminal and another wire to the R terminal.

The supplied Wago nuts are especially useful if you have more than one device already connected to the control board terminals, just like the Central Air Monitor you have already installed.

It's time to power up the central air system so we can configure the Controller and begin controlling the air we breath. 

 


 

Completing the Installation

Configuring your Customer and Central Air Monitor Details

 

In the HAVEN IAQ App, follow the prompts to complete the install, including entering in the customer’s information if you haven’t already done so.  

 

During setup, you’ll be asked to select a Monitor to associate with your Controller. As long as you are using the same account and address for this install as you used with the Monitor install, this Monitor should show up in your list.

 
  • Choose your installation type and find or add your customer & dwelling information.
    • If they have an existing account, just enter their email address and our system will find them
    • If they don't have an account you can add their information manually.
  • Select the appropriate device (Central Air Controller) and deployment type from the lists and continue by selecting next.

During setup, you’ll be asked to select a Monitor to associate with your Controller. As long as you are using the same account and address for this install as you used with the Monitor install, this Monitor should show up in your list. 

  • If this Controller is for personal use, then select Personal Use Program in the Deployment type. 
    • The other three Selections - sale to homeowner, Short term investigation, and service contract - are used when you are installing the Monitor in a customer’s home.

Configuring the Controller Terminals
  • The Monitor was preconfigured with a Zone and an air handler during installation, which is what will be shown in the Equipment step. 
  • If you’re connecting the Controller to the G terminal on your air handler as shown in Figure 2, then select the Central Air Handler associated with your Monitor. 
  • If you are connecting the Controller to a different piece of equipment, select the “Set up new equipment” and select the template you want to use. 
  • If you’re connecting to the G terminal of the air handler, it will tell you that a blower schedule will be enabled, which turns on the blower intermittently throughout the day. 
  • With new equipment, It will ask you if this output is controlling a blower motor that supplies airflow to the Monitor. 
    • In most cases, you should to select “No”, which will disable the blower on this output. 

The Controls step will ask you what Monitor measurement should be used to activate the output. What you get shown here depends on the equipment template you used. 

 

For example - if your central air system has a filter rated MERV 11 or higher, you should select PM2.5 as your measurement for the automation.  You can set the automation threshold to either Fair or Poor, depending on how sensitive the home’s occupants are to IAQ issues.

  • Setting the automation to trigger on Fair is appropriate for sensitive individuals, but most homes should be fine with the automation threshold set to poor.
  • If you are also connecting a second piece of equipment, please repeat the setup steps for this terminal as well. Otherwise, select skip this terminal.
  • The next step is to connect to the Controller from your phone, so make sure you have Bluetooth turned on on your phone.
  • The App will attempt to connect to your Controller over Bluetooth, and then it will take you through a test sequence of the equipment you’ve connected.
  • If the equipment doesn’t turn on during the 15-second test, please check your wiring and try again.
    • You'll need to visually verify this step so ensure you can see the Controller and its LEDs.

WiFi & Firmware Updates

  • Next, you will connect the Controller to WiFi. Make sure you’ve typed the network name and password properly, and the Controller should start blinking blue and then green. 
    • You can also select your customer's WiFi SSID from the drop down menu if you have not already entered the details.
    • This step may take 30 seconds to a minute to complete.

Finally, when the device connects to the WiFi network, it may need a firmware update. The app should make you aware of this, and you'll be able to tell on the device because the power LED will be flashing green and aqua rapidly. It may take a couple minutes to resolve, after which it should land in a solid, non-blinking green, with an aqua flash once per minute. This flash signals that the device is successfully connected to the cloud.
