Lighting Timers, 24-Hour On/Off; Light Flip Box Control - Agrowtek GrowControl GC-Pro Operation Manual

Lights Timers
The controller has special timer controls for lighting equipment including two 24-hour lighting timers (one for each zone,) each
with their own secondary 'B' bank. The 'B' bank can be delayed to activate after the 'A' bank for reduced electrical load on
start-up.
Each lighting stage has its own hot-fire prevention timer which will prevent the lighting outputs from re-activating for a set
duration once turned off. The hot fire prevention timer ensures lamp bulbs and ballasts will not be damaged due to hot-firing.
See 'System Settings' for hot-fire timer configuration.

Light-Flip Box Control
TM
GrowControl is designed to safely and properly switch over lights on a light flip box. For extended light flip box contactor life,
ballasts should be turned off prior to switching the flip box trigger position. This prevents arcing and burning of the contacts
and also ensures the ballasts fire the bulbs properly after being switched.
Simply set the time of day to turn the flip trigger on and off and enter a delay time for switching. The delay time (seconds) will
be applied after turning off the lighting output before changing the state of the flip trigger, and after the trigger has been
flipped before re-starting the lights.
