What the HID-1 controls...
The HID-1 has been designed to control both your Daytime and
Nighttime devices.
1) HID lights that must turn ON and OFF at the proper times.
The HID-1 also protects your HID lights from “Hot-starts”.
Even more important is the HID-1’s ability to monitor the tem-
perature inside the growing area and turn off the HID lights if
the temp rises above a safe setpoint, saving crop loss in the
event of a ventilation failure.
2) Night devices that only need to be activated at night when the
lights are off. You could connect a small ventilation fan, a
heater, a de-humidifier etc.
Light On receptacle: 1 provided
The light On receptacle is used to control your HID or other
supplemental lighting. Any 120 volt lighting less than 1200 watts
combined can be connected to the Light On receptacle. To control more
than one light, a power splitter can be used. If multiple high wattage lights
are to be controlled, an optional HPH-4 o r HPH-8 lighting controller
can be connected to control as many HID lights as required. Each HPH-4
can control up to (4) 1000 watt HID lights. The safety functions built into
the HID-1 keeps your expensive HID lamps safe and protects against
ventilation failures.
(See Max Temp / Hot-start)
Light Off receptacle: 1 provided
The light Off receptacle is used to control any device that needs to be
turned On only at night. The HID-1’s digital timeclock will turn Off the
lights before the night device is turned On. Any 120 volt AC device can be
connected to the Light Off receptacle as long as it is 1200 watts or
(15-amps)or below. Some users have to operate small space heaters only at
night to keep plants from freezing. Since all heaters have an internal
thermostat, simply set the heater thermostat at the minimum level and
plug it into the Light Off receptacle. When the lights turn Off and the area
begins to cool, the heater will take over until “morning” when the lights
are again activated.
Other users may want to activate a small exhaust fan at night to keep
humidity levels for getting too high during transpiration by the plants at
night. There may be other devices only used at night which will work great
with the HID-1.
