The RBT-3000 is a combination Low-Water Safety Cut-Off and Fuel-Saving controller for residential heating systems.

The Low Water Cut-Off is specifically designed to provide burner cut-off if there is an unsafe water loss, which can result from a broken or leaking radiator or pipe, or a cracked section in the boiler.

The Energy saving feature reduces: fuel consumption, wear on boiler parts and burner emissions, by actively managing the burner cycling, in conjunction with the boiler operating-control, to properly match boiler-output to the required load. This controller indicates actual savings on a burner cycle by cycle basis and also indicates the averages of these cycles. All programmable parameters are stored in non-volatile memory.
