The White-Rodgers 13902 SPDT automatic changeover switch with conduit is used to select between two loads

The control works with zone valves and combination hot and chilled water systems, and will automatically changeover the load to the secondary zone when the primary zone is fully open

The switch operates in the automatic "changeover" position when connected to a two-wire load

When in auto changeover mode, the heating or cooling pump will run continuously until manually reset by the white- Rodgers circuit controller (not included)

The two wires are connected to terminals 1-2 when the main power is off or to terminals 2-3 when the main power is on

It is ideal in applications where three-way valves are not permitted or recommended, such as hospitals and schools

The SPDT auto changeover switch will automatically change to the heating or cooling mode when the wafer contacts are energized
