QR code for Installation Manual The Non-A2L Furnace Integration Kit was designed to support the HVAC replacement market for systems containing 1) a Furnace, Indoor Coil and Outdoor Air Conditioner or Heat Pump unit or 2) a Modular Blower, Indoor Coil and Outdoor Air Conditioner or Heat Pump unit. If either the indoor coil or outdoor unit needs to be replaced, both must
be upgraded to R-32 models. If the furnace or modular Blower is still operational, it does not need to be replaced.
NOTE: If the installation check, as detailed in these installation instructions, does not pass successfully and cannot be resolved by calling service for further assistance, the installer must replace the furnace or modular blower with an R-32 compatible furnace or modular blower. The Non-A2L Furnace Integration Kit relies on existing functions of the currently installed furnace or modular blower control boards or PCBs to achieve the necessary mitigation function required for a system utilizing R-32 refrigerant. Therefore, it is important to verify the function of the system, as detailed in the “Verification of R-32 Leak Mitigation” section of this manual.

terminal in the indoor unit by sending a 24VAC signal. It also disconnects the R signal to the thermostat and/or, disconnects ClimateTalk® communication, as applicable. This action will terminate all HVAC operation (Cooling or Heating) while keeping the main blower on to dissipate any refrigerant gas.
NOTE: R-32 is an A2L classified refrigerant which requires a refrigerant leakage detection system to be installed. The Non-A2L Furnace Integration Kit, when connected with an R-32 gas sensor, is a refrigerant leak detection system. The Non-A2L Furnace Integration Kit is designed to be installed externally to the cased coil and furnace. It should never be physically mounted anywhere on the cased coil or the furnace. The kit can be mounted to a wall near the unit, on a wood beam, on the furnace return duct or other locations deemed acceptable. The kit can be mounted using the wall anchors and screws provided with the kit. The kit must always be accessible and serviceable. This manual will explain how to wire and test a new installation where the original furnace or modular blower remains installed while the indoor coil and outdoor unit are replaced with R-32 models.
NON-A2L FURNACE INTEGRATION KIT OPERATING PRINCIPLE
NON-A2L FURNACE INTEGRATION KIT is designed to read R-32 sensor concentration and utilize existing function of indoor PCBs to mitigate R-32 leakage in an unlikely event of a leak in the system. The integration kit continuously monitors the system for R-32 leaks and does not impact the normal operation of the unit when no leak/sensor fault is detected.
A simplified version of operating principle of the integration kit is described here. For a more in-depth understanding of the integration kit’s operating principle, please contact technical service.
The integration kit has two screw terminal headers Indoor Unit (Green) and Thermostat (Black). The integration kit is connected between the thermostat and indoor unit, and it controls the traffic of signals between the thermostat and indoor unit, based on the R-32 concentration. 1. R-32 Concentration detection: The integration kit is
connected to a refrigerant sensor, which detects R-32 concentration. The sensor transmits the concentration, and the integration kit acts based on the concentration. 2. When R-32 concentration is at safe level, the integration kit, does not interfere between the thermostat and indoor unit. All signals are passedthrough. 3. When R-32 concentration is above a certain level or the R-32 sensor or the integration kit encounters a fault, the integration kit, energizes the G (fan)
NON-A2L FURNACE INTEGRATION KIT PRE-CHECKS
The NON-A2L FURNACE INTEGRATION KIT works successfully if the following are true for the thermostat and furnace or modular blower. While these conditions are true for most thermostats and furnace or modular blower, please consult the user manual of the thermostat and furnace or modular blower to verify. If the thermostat or furnace or modular blower does not conform to these common operating principles, please contact technical service to identify a compatible thermostat and/or furnace or modular blower. Do not install R-32 coil and/or outdoor unit if the thermostat or the furnace or modular blower is not compatible. 1. Standard 24VAC Thermostat: R signal of the
thermostat is the source of Y1/Y2, W1/W2, G and other signals. Please verify this by disconnecting the R signal in the thermostat. If the thermostat powers off, then the thermostat is compatible. If the thermostat is still powered on (by alternate power source or battery), lower and increase the thermostat setpoint to activate COOLING and HEATING call, respectively to the indoor unit. In either case, the indoor unit and outdoor unit shall not operate in COOLING or HEATING mode, respectively. 2. Non-communicating Indoor Unit: Noncommunicating indoor units must activate blower fan within 15 seconds, when a G call is presented to activate the blower fan. This can be verified, by putting the system in FAN ONLY mode. The blower shall activate within 15 seconds after the thermostat provides 24VAC on the G terminal. 3. Communicating Indoor Unit: Communicating indoor units must prioritize 24VAC calls, over ClimateTalk® communication and activate blower fan within 15 seconds, when a G call is presented over 24VAC signal. This is true for all ComfortNet systems. However, ComfortBridge systems, may require a firmware upgrade therefore, please do not install the R-32 Coil and outdoor, until the latest firmware is installed in ComfortBridge system, via CoolCloud app (version available for download on your mobile device). 4. Tools Needed: A 1/8″ flat head screwdriver. 5. Identify thermostat wires in the indoor unit and note it down. It will greatly help to identify the wires later.

Please consult the WIRING FOR VARIOUS CONTROL SYSTEM section below, to understand the scope of wiring.
NON-A2L FURNACE INTEGRATION KIT INSTALLATION STEPS
RUNNING THE SYSTEM TEST IS MANDATORY FOR ALL INSTALLATIONS. THE HVAC SYSTEM COMMISSIONING IS NOT COMPLETE UNTIL THE INSTALLATION STEPS LISTED IN THIS MANUAL HAVE BEEN SUCCESSFULLY COMPLETED.
IMPORTANT NOTE: If installing a condensate float switch, see wiring diagram in this IO manual. The float switch must be UL recognized, normally closed float switch that opens a set of contacts as the water level rises. Any other type of float switches are not compatible with this application.
Identify the type of control system being installed.
a. Non-Communicating System (indoor / outdoor units
that only use standard thermostat inputs such as Y,
W and G for control).
b. ComfortBridge Communicating System (indoor unit
contains a ComfortBridge control and is connected
to the outdoor unit using wire terminals labeled 1
and 2. Indoor unit is then connected to thermostat
using standard thermostat inputs such as Y, W and
G). NOTE: If you have this type of system, make sure all available software updates have been made to the indoor control board using the Cool Cloud HVAC Phone Application before continuing to install the Non-A2L Furnace Integration Kit. (2 Stage Furnace: software version 11 or greater. Modulating Furnace: software version 8 or greater. Ultra Low Nox Furnace: software version 11 or greater). c. ComfortBridge Non-Communicating System
(Indoor unit contains a ComfortBridge control but
the outdoor unit is wired as a non-communicating
system meaning standard thermostat inputs such
as Y and W are used. In this case, the indoor unit
ComfortBridge control contains terminals labeled 1
and 2, but they are not in use). NOTE: If you have this type of system, make sure all available software updates have been made to the indoor control board using the Cool Cloud HVAC Phone Application before continuing to install the Non-A2L Furnace Integration Kit. (2 Stage Furnace: software version 11 or greater. Modulating Furnace: software version 8 or greater. Ultra Low Nox Furnace: software version 11 or greater). d. ComfortNet Communicating System (Indoor unit,
Outdoor unit and Thermostat are all connected
using terminals labeled 1 and 2).
e. ComfortNet Communicating System with EEV Coil
(Indoor unit, Outdoor unit, EEV Coil and Thermostat
are all connected using terminals labeled 1 and 2).
f. ComfortNet Mixed Mode System (Indoor unit and
communicating thermostat are connected using
terminals labeled 1 and 2. Single stage non-
communicating outdoor AC unit is controlled by the
indoor control board’s Y terminal).
g. ComfortNet Non-Communicating System (Indoor
and/or outdoor unit contains a ComfortNet control,
but they are not wired together using terminals
labeled 1 and 2. All wiring is done using standard
thermostat inputs such as Y, W and G).

2. Using the appropriate wiring diagram that matches the controls being installed, make all the appropriate wire connections using standard thermostat wire. It is not recommended to insert multiple wires into a single terminal block. Using wire nuts is recommended to achieve this. NOTE: For ComfortNet systems that are using a 4 pin green connector (1, 2, R, C terminals), the kit contains a 5 pin green connector with an added G terminal that is required to complete the wiring. Replace the existing 4 pin green connector with the new 5 pin connector included.
3. Connect the R-32 sensor from the coil to the Non-A2L Furnace Integration Kit control board (4 pin connection point). ATTENTION! AFTER THE CONNECTION OF THE A2L SENSOR AND THE NON-A2L
FURNACE INTEGRATION KIT, ENSURE THE A2L
SENSOR IS KEPT IN ITS ORIGINAL LOCATION
AND CORRECTLY MOUNTED IN THE SENSOR
BRACKET.
IMPORTANT: If sensor is not connected before powering up, the system will enter leak mitigation mode. Once the system enters leak mitigation mode, it may stay there approximately 5 minutes, even if the board loses power (i.e. power cycled). Therefore, it is strongly advised to connect the sensor, before powering up. 4. Turn power on to indoor and outdoor units (this will apply power to the Non-A2L Furnace Integration Kit control board) and make sure the thermostat is in the OFF mode (no cooling or heating calls being made). The red LED on the Non-A2L Furnace Integration Kit control board will start flashing slowly if the control is functioning properly (2 seconds on and 2 seconds off continuously).
NOTE: The indoor blower might run temporarily after power is applied to system (the blower will turn off automatically). NOTE: Any errors will also show up on the red LED of the Non-A2L Furnace Integration Kit Control Board. These will need to be addressed before proceeding with the setup instructions.
5. If a communicating system has been installed (ComfortNet or ComfortBridge), wait until the thermostat or phone application has clearly identified both the indoor unit and outdoor units before proceeding to step 6. NOTE: In a ComfortNet Mixed Mode System, there is a communicating indoor unit, but the outdoor unit is non-communicating. Once the thermostat identifies the indoor unit, it is ok to proceed to step 6.
6. Test all modes of operation with the system to make sure they are functioning properly (Fan Only Mode, Cooling Mode, Heating Mode). This step does not involve the Non-A2L Furnace Integration Kit. The
purpose here is to confirm basic operation of the system before testing the Non-A2L Furnace Integration
Kit functionality. 7. (Mandatory for successful, safe installation) Verification
of R-32 Leak Mitigation depending on one of the below
systems.
7-1. For Systems with a 24VAC Non-Communicating Outdoor Air Conditioner or Heat Pump Perform the control R-32 leakage test for all modes of operation one by one Cooling, Heating, Emergency heating, Constant fan and Idle. Each test will
take approximately 2 to 15 minutes.
a. Set the thermostat to one of the operation modes
and ensure system is running properly in that
mode. Note which mode is being tested. The test
sequence will need to be run again under the other
modes as well.
b. Locate the push button on the Non-A2L Furnace
Integration Kit control and press it two times (See
Reference to the push button on page 2). You
will hear all the relays on the Non-A2L Furnace
Integration Kit control switch as it goes into R-32 leak test mode. The Red LED will also start to flash rapidly during this 5-minute test mode.
c. The HVAC operation that was chosen should turn off (compressor, electric heat, gas heat) after a short period of time (times will vary depending on
the installed system but Electric Heat or Gas Heat should turn off within 30 seconds and the outdoor unit should turn off within 2 minutes). NOTE: If the compressor, electric heat, or gas heat is still operating after 2 minutes, the Non-A2L Furnace Integration Kit is not functioning properly. Please re-check the wiring diagram for your installed system and do not continue until the issue has been resolved. d. The indoor blower will begin to operate within 30
seconds and remain running. NOTE: It is normal for the indoor blower to ramp up or down during this test. NOTE: If a communicating thermostat is installed, a loss of communications error code might be displayed on the thermostat screen during the test. If this does not happen, it is okay to proceed with the testing as long as all HVAC operation, other than the blower, were confirmed to turn off during this test. e. Once steps c and d have been confirmed, the test was successful. It is recommended to wait for the
full 5-minute test to expire. However, pressing the
same push button once will automatically exit this
test mode.
f. Wait for the system to return to the state it was in after the first step, to confirm the system will automatically recover, and then repeat the tests
using the other HVAC modes not previously tested.
It is extremely important to verify the Non-A2L

Furnace Integration Kit will function properly for all
modes of operation.
NOTE: If the Non-A2L Furnace Integration Kit is not functioning properly for any of the modes, please re-check the wiring diagram for your installed system and do not continue until the issue has been resolved.
7-2. For Systems with a Communicating Outdoor Air Conditioner or Heat Pump Perform the control R-32 leakage test for all modes of
operation one by one Cooling, Heating, Emergency heating, Constant fan and Idle. Each test will take
approximately 2 to 15 minutes.
a. Set the thermostat to one of the operation modes
and ensure system is running properly in that
mode. Note which mode is being tested. The test
sequence will need to be run again under the other
modes as well.
b. Disconnect the R32 sensor from the Non-A2L
Furnace Integration Kit control board. The relays
will switch after 5 seconds and the LED will display
a sensor communication fault (3 flashes followed by a 5 second delay before repeating the 3 flashes). c. Electric heat or gas heat will turn off after a short period of time (times will vary depending
on the installed system but Electric Heat or Gas
Heat should turn off within 30 seconds). The Communicating outdoor unit could take up to 12
minutes to turn off. NOTE: If electric heat or gas heat is still operating after 2 minutes, the Non-A2L Furnace Integration Kit is not functioning properly. If the communicating outdoor unit is still operating after 12 minutes, the Non-A2L Furnace Integration Kit is not functioning properly. Please re-check the wiring diagram for your installed system and do not continue until the issue has been resolved. d. The indoor blower will begin to operate within 30
seconds and remain running.
NOTE: It is normal for the indoor blower to ramp up or down during this test. NOTE: If a communicating thermostat is installed, a loss of communications error code might be displayed on the thermostat screen during the test. If this does not happen, it is okay to proceed with the testing as long as all HVAC operation, other than the blower, were confirmed to turn off during this test. e. Once steps C and D have been confirmed, the test was successful. Reconnect the R32 sensor. The
on-board LED will turn solid on once the sensor is
detected and the system will remain in this mode
for 5 minutes before exiting.
NOTE: Power cycling the system will bypass this 5 minute delay period. f. Wait for the system to return to the state it was
in after the first step, to confirm the system will automatically recover, and then repeat the tests using the other HVAC modes not previously tested. It is extremely important to verify the Non-A2L Furnace Integration Kit will function properly for all modes of operation. NOTE: If the Non-A2L Furnace Integration Kit is not functioning properly for any of the modes, please re-check the wiring diagram for your installed system and do not continue until the issue has been resolved.
R-32 LEAK MITIGATION PERFORMANCE
NOTE: If a R-32 leak is detected, the Non-A2L Furnace Integration Kit control will automatically enter R-32 Mitigation mode. R-32 Mitigation mode provides the same performance as seen during the test mode. The NonA2L Furnace Integration Kit will ensure all HVAC system functionality (Heating and Cooling) is off and the indoor blower is running. After the R-32 sensor no longer detects refrigerant, the system will remain in mitigation mode for an additional 5 minutes. During this 5-minute period the red LED will change from a rapid flashing pattern to being continuously on. After 5 minutes, the Non-A2L Furnace Integration Kit will allow the system to return to normal operation and the red LED will start a slow flashing pattern again (2 seconds on and 2 seconds off).
