Description of Stingl Safety Vacuum Release SR-500PS Residential Pool/Spa combination unit.

The new Stingl Model SR-500PS Pool/Spa Combination Switch (Safety Vacuum Release System) is specifically designed for Residential Pool/Spa combinations that share one common pump; and it still provides the same reliable vacuum entrapment detection capabilities as the Model SR-500 Stingl Switch.

The SR-500PS is equipped with two new features:
2 Vacuum memory settings--one for the pool and one for the spa.
Dry contact input for total automation used in conjunction with any remote system (such as a Jandy RS).

Other Features and Benefits:
Complies with ASME/ANSI A112.19.17 (SVRS Standards) as required by the International Building Codes (IBC) and the International Residential Codes (IRC).
Meets all current codes and standards for SVRS’s on new and existing pools and spas.
Newest state-of-art NEC microprocessor technology--guaranteed reliability and performance.
Vacuum monitored 128 times per second--rapid response and accurate readings.
Power monitored 50/60 times per second--insures continuous power detection.
Can act as a pool and spa controller with fully programmable 24 hour timer, or as stand alone SVRS working in conjunction with existing pool and spa controller.
Integrates with existing timer box (for easy retrofit).
Low vacuum sensing (prevents cavitations or running the pump dry, eliminating costly equipment failure).
30 minute maintenance override (for pool or spa service).
Power back-up insures settings and reading will be saved (30 minute rapid recharge).
Display error readout (prevents guessing during troubleshooting).
Works on all size pumps.
Easy and trouble free installation (no pipes to cut or glue).
Turns off pump in milliseconds upon detecting sudden vacuum change.
Multiple audible alarm capabilities --allows for quicker alert to harmful to harmful situations.
Provides a layer of protection, reducing entrapment risk.
