DTC-170 Digital 7-Day Electronic Timer — Professional-Grade Lighting
Control your lighting systems safely & reliably with Vista’s DTC-170.
The DTC-170 incorporates a LCD (liquid crystal display) which accurately displays the time of day in 24-hour format. There are 8 possible “on/off” combinations that can be programmed. For security purposes, the timer has an additional feature that allows for a random variation of 2 to 32 minutes for each “on” and “off” time from the actual time programmed. Adjusting for Daylight Savings Time can be done quickly and easily.
The programming of the timer is maintained during power failures by an internal battery. When the DTC-170 is first installed, it is recommended that the battery be given an opportunity to charge for a few hours before attempting to program the timer.
The DTC-170 from Vista Lighting is a contractor-trusted choice for residential and commercial landscape systems. Sourced through authorized U.S. distribution and backed by the full manufacturer warranty, it delivers the reliability professionals specify on the job.
