FAQ
Q: Connect users between the sensor and the controller,Can it be matched?How long is the length in meters?
A: The user can wire,but it is required to use a 4-core shielded wire,and a 2.5-meter shielded wire is attached to the factory.
The longest distance between the sesor and the controller is 20 meters.
Q: Can WHD Switch control manually and automatically?
A: Yes,but be sure to explain to the customer service before placing an order,it is an unnormal operation.
Q: User have their own sensor,can they buy a controller?
A: No,the sensor and controller need to be used together,2 device can not sold seperately.
