System Features
( )
◆Accurate real-time monitoring
( )
Can display all terminal temperatures in lists and images Various parameters of the controller, such as time, temperature, working mode, operating status, etc. The inspection cycle is short, the response speed is fast, and the system monitoring is accurate and real-time.
( )
◆ Powerful online control
( )
Can control all functions of the terminal thermostat, such as time calibration, temperature setting, mode selection and how to Operation, etc., and can formulate planned tasks so that the system can automatically run according to preset settings.
( )
◆Comprehensive and efficient system management
( )
The management authority and capacity of the system can be set, the operation records of each terminal can be queried, and the system's operation records can be queried. Setting changes can be traced and billing statistics for each terminal can be carried out based on peak and valley electricity prices.
( )
◆ Safe and reliable system operation
( )
Adopt mature industrial-grade communication protocols and take a series of anti-interference and anti-surge measures to ensure the safety and reliability of the system Each terminal can also work independently offline, thus effectively improving the safe operation of the system.
( )
The above characteristics make this system powerful, reliable and easy to operate. On the premise of fully satisfying heating comfort, it can effectively reduce management costs and heating expenses, thereby achieving considerable results. economic benefits.

System composition
( )
◆⑴ Network thermostat
( )
Accepts the instructions from the monitoring center and completes various heating requirements. Various functions: According to the set temperature, control heating section programming, automatic operation in weekly cycles, and provide various working modes and various auxiliary functions according to different needs: overheating protection, floor temperature display, temperature recording, heating time accumulation and various background settings, etc.
( )
◆⑵ Computer and monitoring software
( )
System control software is installed to monitor and manage the entire system: monitor the working status of each thermostat It can control all functions of each thermostat. The control system automatically operates according to a pre-established plan. It conducts billing and management of each user's electricity consumption. Stores and queries the operation of each thermostat, executed plans and end-user operations. Record and set system capacity, administrator permissions, etc.
( )
◆⑶ Data converter
( )
Converts the R3 standard control data output by the computer into R protocol, and transmits it to each unit controller through relay amplification processing
( )
◆⑷ Unit controller
( )
Relays and processes the control signals sent from the computer through the data converter to drive each floor controller.
( )
◆⑸ Floor controller
( )
In addition to transmitting control signals to each thermostat, it also provides DC operating power for each terminal thermostat.
