It replaced my old Honeywell ST6400C programmer exactly as stated. Replaced a defunct ST7100 controller. Exactly the same backplate as old Honeywell 703010000B programmer.

Wiring is different, but easy to configure. Watch this space and fingers crossed it works!

The controller itself has a easy to read display and three on/off positions per 24hrs. Looks like an easy timer to use, with a very clear display.

Excellent. Works well, simple and easy to install. I will change the backplate later, but for now it's up and running.
Came set up with current time and date. You can have each day the same, or different timings for each day.
