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; The evaporator sensor must be installed between the fins of the evaporator in the area, where probably the ice is the thickest.
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 attached transformer and two relays
2. Two temperature sensors
3. One installation stand
