Hydrofarm CAHLC Lighting Controller for Grow Lights - Automatic Timer & Dimmer for Indoor Plants, Hydroponics, Greenhouses - Energy Efficient Grow Light Control System

Advanced HID Lamp control - high temperature shutdown with selectable delaycombines all of The HLC1, HLC2, & HLC3 functions into one unit. Selectable switch lets you choose whether to run the controller for temperature shutdown, on-delay, or both. Temperature shuts off the outlet when chosen temperature is reached (and back on when it comes down 5°). perfect for protecting the crop in the event of overheating. Delay provides a 15 min delay between power up & the HLC outlet on the controller being energized. Eliminates "hot starts" After power interruptions to avoid damaging equipment. Both does both functions; on delay & over temperature protection. The updated controller features increased processor speed, better temperature sensors, higher quality circuit board Components, & more robust engineering. Rated for 15 amps maximum.- now backed by hydrofarm- upgraded circuit boards>- improved performance>- more precise operation.
