This controller is used to operate the ventilation, heating, and wet curtain to establish a comfortable environment for poultry growth.

Features:
1. LCD: 24 letters could be shown
2. High-performance CPU: MicroChip PIC18F4525, instruction cycle is 160ns
3. Totally enclosed case: Grade IP65, touching screen(4*4), 8 LED. Conveniently
4. Operate target: Constant-speed ventilator by 1-5 stage, constant-speed ventilator or wet curtain by the sixth stage, constant-speed ventilator, wet curtain or heating system can be operated by the eighth stage.
5. Independent temperature probe: Four temperature sensors and one humidity sensors could be inserted in the 8-stage controller to get the average temperature of the breeding room soonly and exactly.
6. Minimum ventilated curve: Keep the oxygen and comfortable temperature for breeding room. This device can be adjusted according to the poultry age by customer.
7. Temperature curve: Customer can set a temperature curve to better breeding.

8. Slipped type: When the ventilator is working between the minimum ventilated curve and the top speed in the first stage, customer can set NO. 1 ventilator working time slipped.
9. Alert: Alert and show the unnormal temperature
10. Outside temperature supply: When the outside temperature dropped, the working time of the minimum ventilated curve would be shorted, but the cycle is not changed.
11. Humidity supply: When the humidity is higher, cooling equipment can be colsed or open next ventilator.
12. Special protection: To avoid the accident when the ventilators started at the same time.
13. Overvoltage protection: Fuses would be used in the case of overload or overvoltage time.
14. Virtual mode: Suppose to a plan to show the temperature to watch ventilator working.
15 Computer networking: Connected controllers by RS485 in a area would be controled by a computer which could announce the data to internet.
