The Gavita Master Controller EL allows you to control your Gavita E-series ballasts and gives you maximum control, ease of use, ease of installation and plug and play safety. Simply connect the controller cables to the ballasts with the included T-splitter, set the ballast switches to EXT (external control), and connect the controller:
The controller can turn all connected ballasts on and off with its clock indoors, adjust them to the required output level (in percent or exact output power) and even simulate sunrise and sunset to gradually adjust the climate in the greenhouse as the lights go on or off.
