When you purchase a Noritz SC-301-24M system, you're buying from a manufacturer that has been in business for over 60 years and introduced the original electronically controlled tankless water heater. Noritz's System Controller for NC1991 and NCC1991 units provides a central communication link for up to 24 units. This allows for a fully-modulating operating setup for all units connected to the controller, rotating the operation of installed units to extend device life and ensure even wear. The SC-301-24M includes a pump control that allows for pumps to be connected to the system and controlled by the built-in timer and aquastat features. Only one remote controller is required to control all of the units attached to this system controller and an auxillary backup ensures continued system operation even during partial failure conditions.
