The WT8840C1000 is the Water Heater Control for trade use to replace valves used in Rheem Water Heaters. It has a 1.5" insulation tank and a 4" WC setting.
It is designed for use in Standing Pilot applications using an immersion well for water temperature sensing. An included integrated NTC temperature sensor reads water temperature within the appliance up to 221°F (105°C).
The WT88xx Water Heater Control is designed for use in Standing Pilot applications using an immersion well for water temperature sensing. All models of WT88xx controls include an integrated NTC temperature sensor. The WT88xx controls are powered from a thermopile heated by the standing pilot flame. CS88xx pilot assemblies are designed for use with this control. The immersion well for sensing water temperature has matched NTC thermistor sensors. These sensors provide the fail-safe mechanism through which the WT88xx controls can provide both accurate water temperature control as well as water temperature limit (Temperature Cut-Out [TCO]) function.
