How to Program the Intermatic DT200LT Digital Astronomic Landscape Timer 

Hi, @ask1209! Thank you for the question. If the event you have programmed is currently in the "OFF" position, (for example: lights should be off because it's daytime), then the current state will be displayed on the screen as "OFF". However, if you have it programmed for an "ON" event and the lights are on, but the display continues to show' "OFF", then we recommend calling our technical services team to troubleshoot the issue with you over the phone. You can reach them at 815-675-7000, they're available Mon-Fri from 8AM to 4:30PM, CST. Thank you for being a customer, and thank you again for the question - we appreciate you! LG

The device that you're controlling with the timer needs to be in the "On" position.

Hi Rick! Thank you for the question. The DT620 timer is for indoor use only. We do have quite a few outdoor timers to choose from. To make sure we find the best one to fit your needs, we need to know more about the application for the timer/what you will be using it to control. If you can provide that information, we can provide you with the best options. Thank you in advance! LG

Hi Jack, You'll need to select the time zone you're in (Mountain Standard Time), then follow these steps: Turn the selector knob (H) to select the correct Daylight Savings Time setting. The options are OFF, US/CAN, and Mex. You'll want to choose "OFF" since you live in Arizona, then press SET (D). If you run into any issues or have any questions as you're adjusting these settings, please reach out to our Technical Support Team via www.intermatic.com/en/support.

@@IntermaticIncorporated Thanks so much for your prompt and very clear, helpful instructions. It only took 5 minutes to reprogram the DT200LT and it's up n' running in new daylight savings mode. All customer service should be this good!

Yes it will.

Hi, Kai! Thank you for contacting us. The ON/OFF button can be used to manually turn the timer OFF and ON. An example would be if you need to test the lights (or whatever you are controlling) to see if they work. I hope this helps. Let us know if you have any further questions. Also, you can contact our Technical Services team at 815-675-7000. Their office hours are M-F, 8AM to 4:30PM, CST. They will gladly assist you and answer any questions you have. Thank you again for contacting us. LG
