Brand: Intermatic | Manufacturer Part Number: R8815P101C | Big Frog Supply SKU: R8815P101C
Product Overview
The Intermatic R8815P101C is a complete 24-hour mechanical irrigation timer for compatible 120-volt watering and process-control applications. It combines a DPST timer mechanism with a noncorroding indoor/outdoor Type 3R plastic enclosure and adds a rain-sensor enable/disable switch for use with a compatible separately purchased sensor. The 14-day skipper wheel allows selected watering days to be omitted and supports alternate-day scheduling for water-conscious irrigation programs.
The timer supports up to 44 ON/OFF operations per day with watering intervals from 12 minutes to 20 hours and 45 minutes. An ON/OFF/AUTO control allows watering to be stopped during wet weather or extended during dry periods without changing the tripper positions. Twelve trippers are included for setting multiple operating periods throughout the day.

A rain sensor is not included and must be compatible with the timer and installed according to both manufacturers’ instructions. Electrical installation should be completed by a qualified person with power disconnected.

Why Buy This Product from Big Frog Supply?
The R8815P101C is useful when a 120-volt irrigation system needs mechanical scheduling, a weather-resistant plastic enclosure, and provisions for a compatible rain sensor. Big Frog Supply clearly identifies the sensor as separately sold and distinguishes this model from Intermatic’s 240-volt R8806 controls.
