Master Digital Timer

The Sentinel Master Digital Timer combines the two main timing functions required for hydroponics into ONE convenient package. It combines the function of the DRT-1 recycling timer with an advanced method of SAFELY controlling HID lights. The second timer function is designed to operate like a standard 24-hour time clock to control the plant’s photo-period.

What sets the MDT-1 apart from other time clocks, is the built in functions like “hot-start” prevention logic which starts after a power failure. This function will prevent the HID lamps from re-firing until they properly cool.

The timer also has a built-in temperature sensor that allows the user to set a maximum temp that the area can get to. In the event of a cooling failure, the temperature will rise to unsafe levels. It will automatically shut down the lights to prevent disastrous overheating.

The MDT-1 adds two receptacles to the DRT-1. One receptacle controls lights (Daytime) another one can control Night devices like dehumidifiers.

Connect up to 1200 watts of HID lighting directly to the MDT-1 OR use 1 or more HPH-4 or HPH-8 to be able to operate as many HID lights as you need.
