valves).
The actuator has three different manual settings: AUTO,
OPEN and SWITCH (on 300 psi models only). In AUTO
mode, the valve cycles with the thermostat and activates
the auxiliary switch when valve is at full open.
In OPEN mode, the valve is opened to allow the system to
be filled, flushed or drained. The auxiliary switch is not
activated. The valve returns to AUTO mode when it is
energized.
In SWITCH mode (on 300 psi models only), the valve is
opened and the auxiliary switch is activated to run the
pump. The valve returns to AUTO mode when it is
energized.
