Autotrol 368

Summary

Product Identification

AUTOTROL RESIDENTIAL VALVE 368

Technical Characteristics

• Easy, three-step programming: time-of-day, salt dosage, regeneration interval
• Full range of application settings: water saver and multiple slow-rinse cycles
• Battery-free memory retention: super capacitor provides time-of-day backup
• Water cycling design incorporates the time-tested reliability of Autotrol valve disc technology
• Multiple regeneration functions: quick cycle, delay (next 2 a.m.), instantaneous manual operation and increased regeneration frequency
• Large LED display with icon graphics for system functions (salt dosage, regeneration interval, camshaft position, and more)
• Fast, easy service with front-loading components
