1.5 3-WAY ELECTRONIC CONTROL VALVE
The 3-Way Electronic Control Valve is powered by 24 VAC from the ECS II Control Box. The
Temperature Controller in the Control Box supplies a 4 to 20 mA control signal to precisely
modulate the 3-Way Valve to accurately control the temperature of the DHW output to the
desired setpoint. The Control Valve is shown below. The connection unions have flat face
gaskets that provide the fluid seal.
