Mcdonnell miller model number rbt 3000 is a remote electronic low water cut off control probe for hot water boilers.
When defined parameters are exceeded the new pse 800 makes a decision to shut the burner off based on the volatility variability of the resistance readings.
These controls are used as the secondary lwco on steam boilers and can be used as the primary lwco on hot water heating boilers.
