the computer controller is used for energy-saving control in the computer room or base station cabinet. through effective use of outdoor natural cold sources to exchange heat for the base station of the equipment room to achieve the purpose of energy saving. Provide the communication room with an intelligent fresh air system such as air circulation. It does not have any refrigeration components. It directly introduces the cold air from outside the room and directly discharges the hot air inside the room to achieve natural cooling. It can be used independently or with other major refrigeration and air conditioning systems. The devices together constitute the air conditioning system of the computer room. 
the features of the controller are as follows:
L Compatible with different applications where fresh air or heat pipe heat exchangers are used for heat exchange
LIntegrated current transformer can monitor current in real time
LChinese display, intuitive and clear
LIt can be remotely monitored or connected to an environmental monitoring unit
LCan monitor air conditioning feedback to avoid control failure
LMultiple control options for base station air conditioning: manual/power (transformer)/key (pulse)
L Reserved for differential pressure fault and smoke alarm (or access control)
