Explaining the HID-1
Other digital timers can be difficult to set-up and “Program”.
The HID-1 has been designed to be simple and easy to use.
Separate buttons for each setting make changes easy.
The 24-hour timeclock on the HID-1 keeps track of the actual time in
hours, minutes and seconds and controls supplemental HID lighting.
The 24-hour Light(s) timeclock has two setpoints, one to turn ON the
lights, the other to turn OFF the lights. Normally, HID lights are used
for 12 to 18 hours each day.
The HID-1 also has a “Hi-temp” function which is used to protect
the plants from excessive temperatures by turning OFF supplemental
HID lights if the temperature inside the growing area gets above safe
levels. High temps can be then result of failed ventilation equipment or
high heat loads inside the area. The user can set the maximum
temperature to whatever level they would like to have. Once activated,
the Light outlet remains OFF until the user “resets” the unit by pressing
the Enter / Reset button for 3-seconds.
To protect your HID lamps from “Hot-starts”, the HID-1 also has an
intelligent function that allows the HID lamps to cool properly in the
event of a power outage. The “Light Delay Time” setpoint is preset to
allow the lights to cool for 10 minutes after a power failure. The timer
setting is fully adjustable. This timer is not activated during normal
operation.
Hot-starts can shorten the lifetime of your lamp and can burn out the
igniters in HPS systems prematurely.
