Duct Placement

Just one thing before we kick off the installation: Do not screw the faceplate to the duct until the angle validation step is completed in the IAQ App. You'll thank us for eliminating any extra work, and your customer's ductwork will remain in good condition.

 

1. Turn off the furnace power.

Do not proceed unless this is complete.

 

 

2. Open the furnace door to reveal the furnace control board.

 

3. Determine the optimal Central Air Monitor location.

What to look for

The Central Air Monitor can be installed on both round and rectangular RETURN ducts that are a minimum of 8” in diameter. Optimal location is 24” ahead of the furnace filter in a straight section of the return duct to avoid air turbulence — avoid installing within 24” of a 90-degree elbow.

Airflow in the duct

The Central Air Monitor needs to be installed so that the probe is perpendicular to the airflow; this will ensure that the device accurately measures airborne particles and chemicals. The HAVEN IAQ app allows you to optimize the exact angle at which it’s installed. This helps increase the stability of the airflow signal and maximize the airflow speed through the probe’s air channels.

 

The Central Air Monitor requires 0.4 m/s or 80 fpm of airflow to accurately report data. We recommend confirming this level of airflow with an anemometer prior to installing the probe.

 

 

Within WiFi range

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

4. Mark the location & drill a hole in the center of the duct.

For rectangular ducts: use a 1 ½” hole saw 

For round ducts: use a 2” hole saw

 

 

Wiring & Power

1. Run a length of wire cable (18-24 gauge) from the inside of the furnace to the outside where the Central Air Monitor will be installed. Leave some slack for any future maintenance.

Use a knockout that allows the cable to stay put even when the furnace door is closed. Leave another 4ft of length before snipping the cable to ensure that it reaches the desired Central Air Monitor location in the duct.

 

 

2. Using wire strippers, strip the jacket off both ends of the cable. 

Make sure to leave ½” of exposed conductor on each wire.

 

 

3. Connect the Central Air Monitor to power.

There are multiple methods to connect the Central Air Monitor to power. It is advised to use a non-contact voltage testing tool to confirm that the power is not live before modifying furnace wiring.

 

 

Method 1: Furnace Transformer (recommended)

Find the 24VAC lines (these are usually yellow). Using wire strippers, strip the jacket off the wires, leaving ½” of exposed conductor on both ends of the cable. Using an inline, twist on, push on, or splicing connectors, connect the two ends of the new cable to the dedicated transformer.

 

 

Method 2: Furnace Control Board

Inside the furnace, loosen the terminal screws of the “R” and the “C” terminals. Insert one wire into the “C” terminal and the other one into the “R” terminal. Tighten the screws securely.

 

 

Method 3: External Transformer

You may want to power the Central Air Monitor a wall outlet. If so, we recommend using a 24VAC wall plug as shown in the photo. As with the previous methods, it does not matter which terminal each wire is connected to.

 

Note: To avoid shorting the other side of the wires, avoid plugging this into the wall until STEP 9 is complete.

 

4. Close the furnace door & secure any screws.

 

5. Connect the Central Air Monitor.

  • Connect the other end of the cable to the Central Air Monitor’s terminals.
  • Polarity doesn’t make a difference, secure wires either way.

 

 

6. Turn the furnace back on using the master switch or circuit breaker.

The Central Air Monitor’s LED light should turn solid blue.

 

 

Wireless Configuration

Configure Central Air Monitor to homeowner’s account.

After the LED light turns blue, slide the probe through the mounting plate until it clicks into place. You'll feel a small but noticable click, engaging the mounting plate interlock.

 

 

Provisioning the Central Air Monitor

 

Open the HAVEN IAQ App and begin the provisioning by selecting the Connect a HAVEN device card.

Now is a good time to ensure that you’ve got Bluetooth enabled on your phone.
 

Setup

Once the installation flow is open, follow the sequence to associate the device to the homeowner.

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

You've now added your customer's information, assigned the device to their dwelling, and have completed the initial setup process. You'll be met by a short confirmation panel (like the one below), after each section of the installation has been completed.

Fine Tuning

Just prior to inserting the probe into the duct, we'll fine-tune our HVAC details. Adding accurate information at this stage will ensure that we can offer our homeowners the most accurate and reliable IAQ data and HVAC understanding.

  • Zone 
    • Breaking down the different zones of a home and noting their sq. footage.
  • Air Handler
    • Equipment details on the furnace, A/C, or forced air system.
  • Duct
    • Information regarding the duct shape and size.
  • Filter
    • Filter grade, frequency of changes, and sizing - the HAVEN IAQ app has an onboard filter lifetime.
  • Reference airflow velocity reading (optional)
    • This step, though optional, is highly recommended to ensure a stable airflow signal in order to reduce the need for future troubleshooting visits to the home.

Once completed in full, another panel will appear to confirm that the fine-tuning settings are loading. You're almost ready to validate the airflow.

Validating the Airflow

1. Validate the angle of the probe in the duct.

  • Ensure Bluetooth is turned on, the HAVEN IAQ App will now connect to the HAVEN Central Air Monitor
  • Turn on the forced air-system

  • Place the probe into the drilled hole, starting with the TZOA logo parallel to the airflow in the duct
    • Do not secure the faceplate until the angle validation is complete!
  • If your airflow comes from a different direction you can use the toggle to reverse the direction

  • Optimize angle & secure
    • The system will now test three positions to find the strongest and most reliable airflow.
    • Select Start and the process will run a 10-second validation, hold the probe in place and repeat this step until the app confirms the final position
    • If you cannot find 0.4 m/s or 80 fpm of airflow, consider moving the Monitor to an unobstructed position elsewhere on the return duct.

2. Secure the mounting plate with the self-drilling screws provided.

Once you’ve validated the angle, use a drill or 1/4” hex screwdriver and self-drilling screws to secure the mounting plate in place.

Completing the Installation

 

1. Connect to homeowner's WiFi & finish the installation.

  • Connect to the home’s WiFi network - your customer must supply the WiFi network name and password.
    • Please note the name and password are both case-sensitive!
  • Just before the installation is complete, our system will run a self-analysis on the Monitor, connectivity, and our suite of sensors:
    • Cloud analysis
    • Probe position
    • Relative Humidity sensor
    • Temperature sensor
    • tVOC & PM sensors
    • Confirmation of adequate system airflow
