WHITE-RODGERS 13902 White Rodgers SPDT Automatic Changeover Control for Zone Valves and Combination Hot and Chilled Water Systems

AUTO CHANGEOVER SWITCH WITH CONDUIT

The White-Rodgers 13902 is a single pole double throw automatic changeover switch with conduit kit. It has a pipe body of steel and is UL and ULC listed.

The Automatic Changeover Switch 13901 is a SPDT device with nongrounded changeover contacts and delay coil. This device, which is intended for use on zone valves and combination hot and chilled water systems, has eight-inch leads with strain relief.

Visibility and convenience are the hallmarks of Series 13902 Automatic Changeover Switch. Cast aluminum construction and drip proof NEMA 4X/IP65, this Extra Heavy Duty switch is ideal for single or two factor operation. Series 13902 is an automatic changeover control to provide total reliability in critical applications where overloads, circuit failures, or component damage could result in costly and inconvenient downtime. The SPDT design helps ensure long life of the coils and contacts with field replaceable components by isolating them from line voltage surges through the use of a heavy duty marine grade molded rubber boot. This unit is specifically designed for use

The White-Rodgers 13902 auto changeover switch helps protect against water temperature shock or freeze damage and allows the user to control hot and chilled water applications. The device has an SPDT (single pole, double throw) construction that allows for temperature control of either hot or chilled water. The changeover switch can operate in two different configurations: automatic and manual. In automatic mode, once the desired temperature is reached, the chilled water valve opens and closes automatically to maintain the set water temperature. In manual mode, when it is necessary to have both temperatures controlled individually, the auto changeover function is disabled so that each valves

The White-Rodgers 13902 SPDT automatic changeover switch will operate a zone valve or combination hotwater and chilledwater system. It may be used where a two-way directional valve is controlled by a single control.

White-Rodgers 13902 SPDT Switch is designed for automatic changeover between hot water and chilled water. The device is a direct replacement for the popular 115V thermal vacuum type switch. Changeover occurs when the enthalpy difference between hot and chilled water drops below 2°F. It can also work in combination with zone valves, surface heat exchanges (cold water injection or diverting coils), fan coil units or individual equipment controls (such as air handlers, pumps, valves). Insulation class H/H-NH.
