| 4. Note: |
| 1). Number of temperature, humidity(or temperature) sensor to be connected with WHD72, WHD96, WHD 46 is up to 1,2, 3 respectively; |
| 2). Every sensor match with two control output contacts(passive), connected with heater and fan respectively, the heater is used for rising temperature or removing moisture, the fan is used for decreasing temperature; |
| 3). For RS485 communication and alarming output function, only one can be selected, "-C" for communication,"-J" for alarming.4. The connecting wire maximum length between sensor and controller must not exceed 10 m. |
