Brand: Intermatic | Manufacturer Part Number: R8816P101C | Big Frog Supply SKU: R8816P101C
Product Overview
The Intermatic R8816P101C is a complete 240-volt mechanical irrigation time switch with a 14-day skipper and provisions for a compatible rain sensor. It is designed for landscape watering, greenhouse misting, agricultural feeders, and other approved applications that need several operating periods each day. The timer supports up to 44 ON/OFF settings per day, with individual watering periods from 12 minutes to 20 hours and 45 minutes.
The 14-day skipper allows selected days to be omitted and supports alternate-day operation. An ON/OFF/AUTO control lets the operator pause watering during wet periods or extend operation during dry conditions without moving the programmed trippers. A separate switch enables or disables a connected rain sensor; the sensor itself is not included. The timer mechanism and controls are housed in a gray indoor/outdoor Type 3R plastic enclosure.
