WV4262B Powered Damper
Water Heater Controls
APPLICATION
The WV4262B Water Heater Control System is
designed for power damper water heater applications.
The WV4262B provides these features:
• Gas regulation and manual valve features
• Intermittent spark-to-pilot ignition
• Flame supervision using flame rectification
sensing through the spark rod. This flame sense
circuit uses patented technology to create a
robust sensing signal that is independent of AC
line polarity and appliance earth grounding.
• Water temperature sensing using solid state
sensors potted in a submersion well assembly
• Manually resettable High Temperature Cutout
(TCO)
• Damper motor control with position sensing
• Variable resistance flammable vapor sensor with
a sensing and control algorithm to provide
automatic shutdown when hydrocarbon vapors
such as gasoline are detected
• Retains up to 10 fault code histories in non-
volatile memory (available through the
EnviraCOM™ communication port)
• Solid state setpoint adjustment over a factory
preset temperature range using a linear
potentiometer to provide high resolution
adjustment
Special control features are available to address
items such as stacking. See a Honeywell Product
Specialist for more information.
The specific application of the WV4262B System is
the responsibility of the appliance manufacturer. See
the Specifications below for temperature ranges and
regulator types. The WV4262B system refers to the
combination of the valve and the electronic control
module.

    How to fix low flame signal on Honeywell WV4262B?
    • M
      Michelle BurnettAug 17, 2025
      To address a low flame signal on your Honeywell Water Heater, consider the following: * Check the spark/flame sense rod for any buildup of silicone-dioxide. * Check the spark/flame sense wire insulation.

    What to do if Honeywell Water Heater gives ECO Limit Lockout error?
    • D
      Debra SmithAug 19, 2025
      If your Honeywell Water Heater displays an ECO Limit Lockout error (water temperature exceeds TCO), the control enters permanent lockout after three ECO events. Reset the control by turning the Setpoint knob to its minimum setting for at least 30 seconds, then return the knob to the desired temperature. This limit should not be reached under normal conditions, so check the installation to ensure all manufacturer recommendations were followed. You may also reduce the setpoint temperature to keep the maximum water temperature further away from the ECO trip point.

    What to do if my Honeywell Water Heater has Soft Lockout - Failed Trial For Ignition?
    • C
      Crystal HurstAug 22, 2025
      If your Honeywell Water Heater experiences a Soft Lockout due to a Failed Trial For Ignition, first check the gas supply. If the appliance hasn't been used for a while, ensure air is purged from the gas lines. If the pilot flame lights but the control still locks out (6-1 flash), inspect the flame rod for silicone-dioxide buildup. If you have the tools, check the flame signal strength. If the pilot lights but the flame sense issue persists, consider replacing the control.

    What to do if Honeywell WV4262B has Soft Lockout - Recycle Limit - Flame Lost?
    • T
      Tara WilliamsAug 26, 2025
      If your Honeywell Water Heater shows a Soft Lockout - Recycle Limit because the flame was lost, check the pilot flame to make sure the main flame isn't lifting it away from the flame sense rod. Also, check the gas supply to ensure pressure is maintained when the main burner lights.

    What to do if Honeywell Water Heater detects FVS Fault?
    • J
      jillsalazarAug 28, 2025
      If your Honeywell Water Heater indicates an FVS Fault, first verify the Flammable Vapor Sensor (FVS) is connected. Then, check that the FVS resistance is not below 1.0 K?. Inspect the wiring to the FVS to ensure it is not shorted. If all these checks are okay, you may need to replace the control.
