The climate controller can be set according to three different humidity parameters to control the indoor humidity not to deviate too much from the set value. The control of humidity is particularly important. Good humidity control can make crops grow happily and inhibit the occurrence of pests. Thereby improving crop yield and quality. Users can control the indoor humidity level based on relative humidity, missing humidity values, and evaporative pressure difference (VPD). The dehumidification interval and running time can be set in the controller to control the intermittent operation of the dehumidification program, or the interval time can be set to O to keep it running.

When the greenhouse is heated by hot water and a mixing valve is installed,Climate controller can calculate the heating water temperature of the greenhouse through the Al intelligent algorithm according to the set heating temperature value and the influence of the outdoor weather. 

The application of circulating fans in greenhouses is quite common, which can make the indoor temperature more even. It can also effectively reduce the humidity, thereby avoiding many diseases caused by excessive humidity. Climate controller allows the user to start the circulating fan according to a variety of conditions. Whether to turn on or off can be determined based on humidity level, cooling demand, and fog.When the indoor relative humidity level is too high or the missing humidity value is too low,the circulation fan can be activated to reduce the humidity level. When the cooling amount or the window opening angle is higher than the set value, the circulation fan can be turned off. If you want the circulation fan to running all the time, you can set the set value to 100%. When the greenhouse is  spraying and adding carbon dioxide,the circulation fan can be turned on or off temporarily.

The mist system can effectively increase the humidity level in the greenhouse and reduce the indoor temperature. The mist system can be activated by humidity level, indoor temperature,accumulated light or vapor pressure difference VPD. The mist system can be set to operate at intervals or continuously.When the mist system operates at intervals, the interval time will be determined by the outdoor lights, and the mist interval time is longer when the outdoor is cloudy. When it is sunny outdoors, the mist interval is short. When the indoor relative humidity is too low, mist can be activated to increase the relative humidity. When the indoor temperature is too high,mist can be activated to lower the temperature. When the accumulated light reaches a certain value, the mist can be activated. When the vapor pressure difference is too high, the mist will be activated to replenish water and reduce VPD, which is more conducive to crop growth. The user can set the above conditions to enable or disable certain condition sat the same time to activate the mist system.

The Lighting controlling module is used to control the fill light.Grower can extend the day time and increase the lighting at night through the fill light.Grower can set several groups of the different starting time and ending time of the fill light,the fill light could according to the starting condition to start and end,and it will be closed at other times.The starting time and ending time can be constant and also can be changed according to the astronomical time,the starting condition could be timing starting,lighting cumulative starting or starting according to external lighting conditions.The fill light will be opened when the time reaches the set starting time,and the it will be closed when the time reaches the set sending time.

The light accumulation starting means that the accumulated light during the day is not enough, and it needs to be supplemented by light at night, and the light will be turned off when the accumulated set value is reached.The starting according to external lighting conditions means when the illumination is lower than the set value at day,the fill light will be opened,and it will be closed when the illumination is higher than the set value.The user can set the shortest turn-on time and interval time of the fill light to prevent the frequent turn on and off of the fill light , to protect the rectifier of the fill light.

The Co2 is an essential element for plant growth,it could make plants keep a good growing if control the Co2 under a good concentration level and improve the yield and quality.There are many ways to supplement the CO2,it could be CO2 generator, liquid CO2 and CO2 produced by boiler.When the light level drops, the required CO2 concentration also drops. The task of the climate controller is to use precise and intelligent algorithms,well control the operation of these supplementary equipment,to keep the indoor CO2 concentration in a suitable range for plants.When it under a high light situation and all the vents have been closed,then it need much CO2.When the ventilation window is opened, it will further reduce the CO2

concentration level.The controller allows the user to set the CO2 concentration level under a high light and the CO2 concentration level under a low light. When the light is between high light and low light, the system will automatically calculate the appropriate CO2 concentration value.The user can also set the CO2

concentration value when the temperature is lowered. When the system cools down, the window or fans will open, and the CO2 concentration level needs to be reduced. When the cooling rate exceeds the set value, this operation will be triggered.

The function of customize program make it be possible for users to operate non-standard equipment.The non-standard equipment means not in the system,users can realize their starting and closing condition in the customize program.The customize program needs to set the shortest operation time ,shortest closing time,delayed opening time and delayed closing time such parameter,these settings are helpful when the starting condition changing rapidly,the equipment won't start frequently so that can protect the equipment.
