High temperature control valves,auto zone valve for central heating system valve
Product description
The temperature regulating valve systems, are for water and steam commonly used in heating / cooling supply systems. These systems include a temperature control valve with an internal ball check valve to be opened or closed by manually or electric actuator motor. The ball valves for control of the water supply, and a digital thermostat that displays the outlet temperature.
Functions
- Wireless temperature control valve is divided into wireless temperature controller and smart valve, controller including motor drive and wireless communication part
- The controller senses the environment temperature, and the valve and the thermostat are transmitted by wireless communication module, so that the installation is convenient and the construction is simple
- The controller open and close the valve according to the environment temperature
- Smart valve can transmitted through MBus wires to the collector to control the valve open/close, to achieve the purpose of indoor thermostat
- Real-time display the indoor temperature, open/close state and the default prompt function
Controller
- Power:2* AAA batteries;
- Wireless radio frequency: 430 ~ 434MHz;
- Wireless transmission distance ≥ 200m (open area);
- Range of temperature setting : 4 °C ~ 50 °C;
- Range of the induction temperature range: 0 ° C ~ 70 ° C;
- The accuracy of sensor : ± 0.5 ° C;
- Setting of Beijing time;
- Setting of the required temperature;
- The "ON-OFF" on controller is means that to open or close the the temperature judgments of the controller, not equal to open and close the valve;
- The “OFF” on controller is means that to close temperature control function (equivalent to set the temperature of 99 ℃), the actually implement to “Opening” command and keep the valve to open position;
- The controller received the wireless synchronization signal and update the latest control state per 3 minute;
- The controller and the control module inside valves is one to one, real-time and re-code;
Technical introduction
- Work voltage:DC12V or DC24V
- Wireless radio frequency: 430 ~ 434MHz;
- The current temperature is lower than the set temperature (set temperature :-1), then the inside wireless control module implement command of” Opening” and the valve be open;
- The current temperature is higher than the set temperature (set temperature :+1), then the inside wireless control module implement command of” Closing” and the valve be closed;
- The valve keep open position when power-off;
- The valve will keep open position as soon as the controller is more than 10 min without receiving the remote control of the wireless synchronization signal;
- The controller update to detect the current temperature per 3 secs;
- The controller just power -on without remote control, the valve keep opening position;
