Intermatic DT200LT Digital Astronomic Landscape Timer - Precision

In this review of the Intermatic DT200LT timer, the bottom line is simple: it is a straightforward, durable choice for homeowners and installers who need reliable automated control of low-voltage landscape and decorative lighting. The main reason to buy is its combination of easy programming and astronomic timing, which automatically follows sunrise and sunset so lights turn on and off at the right times without daily adjustments. The unit also keeps settings for months on battery backup, making it practical for seasonal installations and outdoor environments.

Key Features

• User-friendly programming: The one-push override and simple controls let users make quick schedule changes without navigating complex menus.
• Effortless automation: Built-in auto DST and astronomic scheduling mean the timer adjusts for daylight changes and seasonal daylight saving time automatically.
• Versatile compatibility: Rated for low-voltage transformers up to 1200W, it can handle landscape lighting, pool pump circuits used on low-voltage systems, and holiday lighting with confidence.
• Extreme climate reliability: The DT200LT is designed to operate from -40 F to 122 F, providing dependable performance in harsh outdoor conditions.
• Long-lasting settings: Two included LR44 batteries retain programming for up to three months without power so settings are preserved during maintenance or outages.

Who It's For

The Intermatic DT200LT is best for homeowners, landscapers, and property managers who want a reliable, programmable way to control low-voltage landscape lighting and decorative lights. Installers who work with Volt or similar low-voltage transformers will appreciate that it fits many transformer applications and that customers report easy setup and accurate timing.

It is less suitable for users who need wireless app control or smart home integration, since this is a stand-alone digital astronomic timer with physical programming. Also, some users may find physical fitment differences when replacing older timers in landscape boxes, so check dimensions before planning an in-place swap.
