Device & Installation Overview

The TZOA HAVEN Central Air Monitor is an in-duct air quality system that tracks particulate matter and volatile organic chemicals. By being positioned in the return duct, in front of the furnace and air filter, HAVEN is able to detect air pollution and other environmental factors that travel through the entire home.  The homeowner gets a 24/7 dashboard view in the HAVEN IAQ app (for iOS and Android), as well as notifications of indoor and outdoor air quality events.

The Central Air Monitor Installation Instructions are also included in the HAVEN Pro Training program via the HAVEN Pro Portal. We recommend that all HAVEN Professionals complete the HAVEN Pro Training before installing or servicing any HAVEN device.

Requirements for Installation

Prerequisites

  • Ducted central air system

    • Suitable for any duct (round and rectangular) minimum 8" wide

  • Within range of WiFi

    • 802.11 b/g/n

    • WPA or Open

Parts included

  • HAVEN Central Air Monitor Kit

    • Central Air Monitor

    • Mounting plate

    • Gaskets

    • Screws

    • 2mm slotted screwdriver

    • Wago splicing connectors

  • ~12ft of 2 wire cable (18-24 gauge)

  • Optional - 24VAC wall plug

Tools needed

  • Drill

  • Hole saw (1 ½” for rectangular ducts, 2” for round ducts)

  • 1/4” hex driver

  • Wire Strippers

  • Android or iOS phone

  • Optional - non-contact voltage testing tool

Duct Placement

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.

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

Wiring & Power

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

6. Using wire strippers, strip the jacket off both ends of the cable, leaving ½” of exposed conductor on each wire.

7. Connect the Central Air Monitor to power.

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 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 of the furnace, loosen the terminal screws of the “R” and the “C” terminals. Insert one wire into the “C” terminal and 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. To avoid shorting the other side of the wires, avoid plugging this into the wall until STEP 9 is complete.

8. Close the furnace door & secure any screws.

9. Connect the Central Air Monitor.

 

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

 

 

Wireless Configuration

11. Configure Central Air Monitor to homeowner’s account.

 

Completing the Installation

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

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

14. Connect to WiFi & finish the installation.
