BF-200A+ upper/lower limit temperature controller can be widely used for solar heat pump water heating, and various applications requiring heating control.
For one-channel temperature measurement, BESFUL NTC-220 thermistor is used to measure temperature with a display accuracy up to 0.1 ℃, allowing users to intuitively monitor the temperature rise and fall trends. For one-channel output, a relay (NO/NC contact) is controlled to output temperature control within the range of 0 ℃～120 ℃. It is easy to set up these parameters by directly adjusting the upper and lower limits to the desired values.
Thanks to the wide range of rated power supply, the controller is able to ensure stable, reliable and durable operation by adapting to AC80V～240V power supply.
