This solution uses network control mode，through telephone, wireless remote control、internet remote control water heater work state, satisfies your demand of hot water at anytime and anywhere. The entire solution uses the newest embedded technical achievement, the entire solution stability is high, cost is low, installment is simple, can plug and play, and saves energy.
　Function introduced:
　Uses network control mode，realize 4 remote control methods of traversing time and space:
　1、 Can choose through wireless remote control to control water heater;
　2、 Can choose through internet to monitor water heater work state and remote control water heater work state at any moment;
　3、 Through telephone control water heater work state, realize bespoke , on and off of water heater;
　4、 Can fix many handset users through server, realize handset message to remote state control and monitor of water heater, saving waiting time, avoiding waste source about long-time heater.
　Besides，can realize water heater protecting function ,such as excess temperature protection, parched protection, creepage protection and so on.

Electric water heater network remote controller

　Product characteristic:
　1、Each controller can independently compose many unattached system to control water heater, can select control mode of water heater at one's pleasure.
　2、Wireless remote control CMOS chip uses IA4421 of Intergration company of America, remote control distance can reach above 30 meters, at least can penetrate a wall of 20cm to control.
　3、Network controller and water heater controller use wireless control mode, avoiding routing bother when install water heater.
　Technical parameter:
　Wireless communication frequency：Two-way transmission，433 MHz
　Wireless communication speed：≥9.6 Kbps
　Ethernet interface:10M
　Handset/telephone control decoding mode：DTMF(double audio frequency decoding)
　Ambient temperature when use：-40℃～＋75℃
　Relative humidity when use：Below 95%RH（when room temperature 25℃）
　Application mode:
　Because uses separate embedded control module, can realize free combination of each function, convenient for water heater factory to develop new product, simultaneity, provide many selection mode to water heater terminal customer.　
　1. Can solely select telephone remote control mode, can select wireless transmitting telephone control instruction, avoiding routing bother, just install a module alongside of telephone, can realize telephone remote control.
　2. Can solely select network remote control mode, field only uses Microchip PIC18F66J60 to aim at embedded system, integration rate is high, stability is strong, cost is low.
　3. Wireless remote control solution choice is flexible, can select infrared control mode, wireless control mode, or doesn’t remote control, doesn’t affect other functions of the entire plan.
　4. Can select message control mode, only need to unify network control module, doesn’t increase hardware cost of the terminal customer.
