WV4460E Power Vent Water
Heater Controls
APPLICATION
The WV4460E Water Heater Control System is designed
for power vent water heater applications.
The WV4460E 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)
• Induced draft blower motor control
• Draft proving switch sensing via pressure switch
• 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 Resideo Product Specialist for
more information.
The specific application of the WV4460E System is the
responsibility of the appliance manufacturer. See the
Specifications below for temperature ranges and
regulator types. The WV4460E system refers to the
combination of the valve (VT8804A) and the electronic
control module (WT4834Q).
