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.
