Automatic Boiler Controller advantages:

• Measure the boiler water level by a sight glass sensor

• Control the water level in the boiler

• Measure the pressure in the boiler

• Control the pressure in the boiler (small fluctuation)

• Measure the feeder tank water level

• If the feeder tank and the boiler run out of water set the burner to pilot light and switch the ALERT led ON

• Wide range input voltage

• Polarity protection

• Ability to control an electric pump
