The SUPERPRO CRL-1 Combination Recycling and Lighting Timer offers horticulturists some of the most essential safety features available to control supplemental lighting and hydroponic pumps.

SUPERPRO CRL-1 Features

1. Features a 24-hour digital clock capable of turning lighting ON and OFF at the user's specified times.

2. When using supplemental HID or CFL or LED lighting, it is vital to ensure the grow lights do not raise growing temperatures beyond a safe level. The "high-temperature shutdown" feature uses an external temperature sensor connected to the CRL-1 to turn off the light fixtures if an unsafe temperature is detected.

3. Monitors the incoming power and makes sure the lighting fixtures will not attempt to re-strike lamps until they are correctly cooled down after a power failure.

4. The Superpro CRL-1 features a "recycling timer" function that controls any device working on a repeating schedule. The "recycling timer" is programmable to work during the day, night, or 24-hours. The timing feature is versatile, accurate, and can be adjusted from 1 second to 96 hours.
