1.BF-D215B + LED display the current temperature difference, you can see high and low temperature zone temperature measurement point temperature; 2. high and low temperature and the temperature difference between the value of the temperature difference set value, and the temperature difference between the lower back to the difference between the control relay output; 3 . realization antifreeze circulating collector plate; 4. have temperature deviation correction function, can effectively adjust the temperature deviation due to the long distance transmission or caused by different measurement points; 5. power supply AC90V ~ 250V;
Functional overview
BF-D215B + microcomputer temperature control, mainly used in hot water circulation, backwater system control and other occasions o LED screen real-time display the current temperature difference, and can always view the high and low temperature zone
Temperature value of temperature measurement. Through the high and low temperature zone between the temperature difference and set the temperature difference, and the temperature difference between the lower part of the hysteresis to solve the relay output, to achieve cold and heat cycle, improve thermal efficiency,
But also to achieve the collector plate antifreeze cycle. At the same time with the temperature deviation correction function, can effectively correct due to long-distance transmission or due to different temperature points built temperature deviation o BF-D215B +
Ready to adjust the temperature deviation correction function, can effectively adjust the long distance from the transmission or due to different temperature points built temperature deviation o BF-D215B + with advanced power supply design, to ensure that the power supply
The controller is stable, reliable and continuous when changing between Ac90V and 250V.
