Up to 4 TR9299-WiFi. battery powered CO2 and Temp transmitters can be placed in a space to control an RTU. Control is based on highest level measured. The GW4201-A WiFi gateway is placed in the RTU. It receives the WiFi CO2 signal(s) directly and provides a 0-10 Volt signal to the RTU to control based on CO2 levels. WiFi antenna for gateway can be mounted outside RTU or extended down return air duct into the space. 24 VAC power is requred. 15 to 30 minutes installation time per RTU.

The AirTest TR9210-B WiFi thermostat can be added to the installation for additional benefits: • Replaces most existing thermostats using existing wires. 24 VAC powered. • Local CO2 readings from the TR9299 are displayed on the thermostat. • CO2 signal is passed to the RTU over existing thermostat wires. Useful when the WiFi connection to the RTU may be weak. • Thermostat can be adjusted, including lockout options using the WiFi connection on a smartphone or tablet. In the RTU, the GW4201 gateway connects to the RTU CO2 input and to the Thermostat contacts in the RTU. 24VAC power is required. 20 to 40 minutes installation time per RTU.

Most RTUs have a CO2 Demand Controlled Ventilation input that is not being used. AirTest’s WiFi CO2 retrofit allows for a fast and easy energy efficiency upgrade to most any RTU. The WiFi connection is made peer-to-peer eliminating the need to tap into an existing network. Utility rebates are available in most areas.

Additional Installation Options

The GW4205 is a cellular modem and WiFi transmitter that can provide a remote connection for up to 12 RTU installations. Data can be sent to any web address or to a dedicated web portal that provides: • Display of current and historical CO2 levels. • Display of thermostat settings and current and historical readings. • Provides remote thermostat setting adjustments. • Will provide power reading if the TR9215-3CT-BT is included. • Set up email and text alerts. Ideally the modem is mounted in conditioned space. RTU gateways communicate via WiFi to modem. there is a small annual web portal fee in addition to equiptment purchase. Need for a cellular connection can be eliminated if a local WiFi internet connection is available. 5 to 15 minutes installation time per site.

AirTest also offers the TR9215-3CT-BT module that can be used to measure current for 3 phase power or single phase current for two compressors and one fan. This module communicates via Bluetooth to the GW4201-B module. Bluetooth has excellent communication capabilities within and around the RTU. Up to 4 CTs are possible. This is designed to be used with the web portal to view current and historical data. 5 to 15 minutes installation time per RTU.

The AirTest TR9299 CO2 and temperature sensor can also be easily integrated into existing BACnet®, Modbus or SNMP networks using the BB2-7010-06 gateway. The TR9299 sensors are logged into an existing WiFi network and addressed to the gateway. The BB2-7010-06 gateway is connected to one of the routers on the network. Up to 200 sensor can be connected. Using an IP connection to the building control network the gateway identifies all CO2 sensors as BACnet®/Modbus control objects in the gateway web server.

Option 3: Add Cellular Modem & Web Portal

Option 4: Add Wireless Power Monitoring (CTs)
