Typical Application Wiring Diagrams:
The timer box can be configured for 120 VAC, 240 VAC, or 277 VAC. Jumper wires J1 and J2 (16 AWG) are used for the timer power supply.
- 120VAC Application Controlling One 120VAC Load: Diagram shows L and N connected to the timer's L and N terminals. J1 connects L to COM1. The load is connected between NO1 and N.
- 120VAC Application Controlling Two 120VAC Loads: Diagram shows L and N connected to the timer's L and N terminals. J1 connects L to COM1. The first load is connected between NO1 and N. J2 connects L to COM2. The second load is connected between NO2 and N.
- 240VAC Application Controlling One 240VAC Load: Diagram shows L1 and L2 (240VAC) connected to the timer's L and N terminals respectively. J1 connects L1 to COM1. The load is connected between NO1 and L2. J2 connects L2 to COM2 (unused in this configuration).
- 277VAC Application Controlling Two 277VAC Loads: Diagram shows L and N (277VAC) connected to the timer's L and N terminals. J1 connects L to COM1. The first load is connected between NO1 and N. J2 connects L to COM2. The second load is connected between NO2 and N.
Hot Water Heater Typical Wiring Diagram: Illustrates a specific wiring setup for a hot water heater using the timer box, showing connections to a 120VAC hot water tank and a 240VAC (Dualphase) circuit breaker box.
