How to set the time controller?
How to install a time controller?
Two wiring methods:
When the power of the electrical appliance does not exceed 1320W:
The neutral wire of the air switch is connected to the inlet of the time controller, and the neutral wire of the electrical appliance is
connected to the outlet of the time controller.
Time Controller
When the power of the electrical appliance does not exceed 1320W, a 220V AC contactor is required:
1. Connect the fire neutral wire of the air switch to the inlet of the time controller, and then connect another set of fire
neutral wires from the air switch to L1 and L2 of the 220V AC contactor.
2. The output terminals of the time controller are connected to A1 and A2 of the AC contactor, and the neutral wire of the
electrical appliance is connected to T1 and T2 of the AC contactor.
