IMPORTANT
• Using a previously configured / used FARMOD is allowed, however, the user should exercise caution when doing so as it
could result in reliability issues if the usage/history of the FARMOD is unknown.
• The SV2 Series valves have internal algorithms that prevent the accidental or intentional removing of the Fuel Air Ratio
Module once the valve has been fully setup and is in use. If the FARMOD cable is disconnected, the valve will lockout.
• The fuel/air valves (V2V) FARMOD and main electronics CANNOT be replaced at the same time or all Honeywell and OEM
factory + field data will be lost, including the valve-specific stepper motor full stroke calibration. If both components must
be replaced, the installer must replace 1 at a time. Follow the Fuel/Air Ratio Module Change-Out Procedure outlined in this
chapter, restoring power after to preserve the configuration. Then follow the Valve Main Electronics Change-Out Procedure
in Chapter 9. This will preserve the most setup parameters.
New FARMOD Procedure
1. Replace module on valve per instructions in the SV2 Series Valve Fuel Air Ratio Modules installation instruction document,
32-00040, which is packed with the replacement Fuel/Air Module.
2. Once the valve is repowered, there will be 2 active faults present. Refer to
