Which terminals on an infinite heat switch should the power lines be connected to?

The power lines for an infinite heat switch should be connected to the L1 and L2 terminals. These terminals are specifically designed to handle the incoming line power, ensuring that the switch can correctly control the flow of electricity to the heating element. The L1 and L2 labels typically represent the line connections in an electrical circuit, making them the appropriate choice for facilitating proper heating operations.

Connecting to H1 and H2 would not be suitable, as these terminals are usually associated with the high or heating elements and not meant for direct power line connections. Similarly, the P terminal generally stands for a control terminal or a signal input rather than a direct power connection, which is why connecting to P in combination with L2 or L1 does not fulfill the requirement for power line terminals effectively. Therefore, the clear choice for connecting power lines is L1 and L2.
