How do I wire my WSM-63 to my DS2 controller?
Wire Your Heating System to Your Controller
Wiring the WSM-63 and DS2 together is a great way to be able to control the WSM-63 timer panel with an automatic sensor. You will power the 120V coil of the WSM-63 with one leg of 240VAc and the neutral. Do NOT run both hots to the WSM-63. For more, please refer to the installation manuals or find the diagram here or below.
