KD2 SERIES offers a unique combination of sophisticated features and familiar operation, making it the ideal residential controller from Irritrol®. Its automatic, semi-automatic and manual operations, a wide range of watering intervals, and the ability to make percentage changes to watering duration for seasonal adjustments provides excellent scheduling flexibility. Electrical surge protection, self-diagnostic function, an electronic circuit breaker, and a five-year warranty provide peace of mind for years to come. In addition, non-volatile memory maintains program information and built-in memory maintains date and time when AC power is lost. KD2 SERIES is compatible with the CLIMATE LOGIC® Weather Sensing System which adjusts run time based on on-site weather information and the SMRT Logic® gateway for app-based remote system control.
