Rail Type Temperature Difference Meter Solar Hot Water Circulation Temperature Difference Controller
Rail Type Temperature Difference Meter Solar Hot Water Circulation Temperature Difference ControllerDescription
BF-D215B+ microcomputer temperature difference controller is mainly used in hot water circulation, return water system control and other occasions. The LED screen displays the current temperature difference value in real time, and can view the temperature difference value between the high and low temperature areas, the set temperature difference value, and the temperature difference lower limit return difference value at any time to control the relay output, realize the cooling and heating cycle, improve the thermal efficiency, and also realize the integration Antifreeze cycle of hot plate. At the same time, it has the temperature measurement deviation correction function, which can effectively correct the temperature deviation caused by long-distance transmission or due to different temperature measurement points.
