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 installation the sensor shall be placed with the head upward and the wire downward.

 

3.In case of long-distance sensor installation from the controller, the sensor cable may be prolonged up to 100 m max. without any re-calibration

 

4.The temperature controller can not be installed in the area with water drops.

 

Accessories for the temperature controller:

 

1. One temperature sensor

2. One relay

3. One attached transformer
