C. Components
The WUD device consists of two components:
1) a Thermostat and
2) a Solenoid
1. Thermostat
A thermostat mounted on the Heat Exchanger of the water heater (Figure 1) and connected internally
to the 12VDC power. The power connection is made after the Power ON/OFF switch located on
the GSW-1; NOTE: power is NOT supplied unless the switch is in the ON position.
.
Figure 1
The output of the thermostat is provided at the electrical connections on the
back of the water heater (Orange wire) to provide power to the Solenoid valve
as needed (Figure 2).
