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 Honeywell 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).
