How To Wire the DS-2C Controller ?
TYPICAL LOAD WIRING OF THE DS-2C CONTROLLER
The Yellow load leads are N.O. contacts and do not supply power directly to your load. The relay inside the DS-2C acts as a switch. While not as convenient as directly supplying power for the load this allows you to operate the DS-2C from one voltage while controlling a load of a different voltage without adding an external relay or contactor. For example, the DS-2C can be powered from 120VAC but can directly control a 24VAC signal for a boiler system or 277VAC for the heating wire.
The following diagrams show a possible wiring scheme for connecting the DS-2C to your load. Your load may be a direct connection to heat cable, a heater, a contactor coil, or a control voltage. For clarity, the green safety GROUND leads are not shown.
