 Water tower pump linkage control system for 
 Jinan the Tenda Electronic Technology Co., Ltd. developed water tower pump linkage control system is based on the GSM wireless network between the two GSM controller to communicate with each other to achieve the automatic control of cooling towers pump. No wiring, truly wireless remote control. The system is simple, easy installation, stable signal, a unique alarm system to improve the reliability and safety of the water tower water level automatic control. 

 Water tower pump linkage control system components 
 Two GSM SMS remote controller, 12V power output, antenna, level probe float. 

 Water tower pump linkage control system installation process 
 Two phone card into the GSM remote controller. 
 Pump remote controller output series all the way to the pump contactor coil. 
 Towers remote controller to the water tower next to the / pool (Note waterproof), and two float respectively fixed to the bottom of the water tower (lower limit) and top (upper limit). The user can set their own limits. 

 Water tower pump linkage control system linkage process 
 Towers remote controller through the stainless steel float real-time detection of towers / water level in the pool when the water level reaches the upper limit, the water tower of the remote controller to the pump remote controller to send text messages off the pump, the pump stops pumping; when the water level reaches the lower limit, the water tower remote controller remote controller to send text messages to pump a pump, the pump starts pumping. If the pump is not the action, controller alarm SMS is sent to the owner. 

 The water tower pump linkage control system advantages: 
 Linkage control system automatically without human intervention, automation can only control. 
 With the GSM mobile network, the controller signal stability, wireless remote control, free from the constraints of time. 
 Can be set up to 5 groups of alarm number. Alarm numbers can be changed or deleted. 
 Flexible control. Automatic control, can also manually send text messages control, so that special circumstances did not reach the assembly line will start the pump water supply. 
 Send text messages to complete remote communications, and low cost. 
 The master can send text messages at any time to query the pump state. 
 Will float level sensor instead, the user can query a specific water level. 
 12V power supply, the whole power consumption of 24V, energy saving, environmental protection, energy saving. 
 Controller to adapt to various work environments to solve the problem of people wiring. 
 This control system has been put on the market for many years, the continuous improvement of product performance, users can be assured.
