APCTMDT Autopilot Master Digital Timer

Combination Recycling and Lighting Time

The Autopilot Master Digital Timer (MDT) controls lighting and timed recycling functions in your grow area. The MDT has simultaneous dual timer functions, a 24 hour time clock for lighting and a precise cycle timer for pumps, CO₂ injection, exhaust, intake, etc. The MDT has four outlets. One outlet controls a pump or other recycling device; two outlets control daytime devices such as lights and light movers; and one outlet controls a nighttime device such as a heater, dehumidifier, or exhaust fan. 

The MDT features a "high temperature shutdown" function that detects unsafe high temperatures in the grow room and turns off the HID lights in the event of a ventilation failure. The MDT also features hot start protection to ensure proper lamp cooling before attempting to re-fire. 

• Precise digital time clock with battery backup
• Adjustable high temperature shutdown and hot start prevention
• Recycling on/off range: 1 second to 96 hours
• 3' remote temperature probe

NOTE: This controller has a 14.5A maximum load. For higher amperage units, or combined lighting wattage above 1200W, it is recommended to use a lighting controller.
