Retrofit control module for reverse osmosis system and method for using same

A retrofit control module comprising:

• a housing;
• a controller configurable to control a reverse osmosis system, the controller being located within the housing, the controller comprising:
• a first communication interface, the first communication interface being connectable to the reverse osmosis system;
• a processing unit operatively connected to the first communication interface;
• and
• a non-transitory storage medium operatively connected to the processing unit, the non-transitory storage medium storing computer-readable instructions thereon;
• the processing unit, upon executing the computer-readable instructions, being configured for:
• receiving, via the first communication interface, at least one parameter of the reverse osmosis system;
• comparing the at least one parameter of the reverse osmosis system with a predetermined threshold;
• and
• in response to the comparing:
• transmitting a control parameter to the reverse osmosis system, the control parameter causing the reverse osmosis system to control at least one component of the reverse osmosis system.
