Notes for Installation:
1. Sensor leads must be kept separately from main voltage wires in order to avoid high
frequency noise induced. Separate the power supply of the loads from the power supply of
the controller.
2. When installing, the sensor must be placed with the head upward and the wire downward
3. The temperature controller must not be installed in an area where water drips.
