Single module optimizing controller capable of operating one of a plurality of different types of HVACR systems

A method for reducing the energy usage of a heating, ventilation, air conditioning and refrigeration (HVACR) system having an optimizing controller capable of operating the HVACR system and at least one evaporator coil, the optimizing controller including:

• a communications section for communicating with at least one remote controller terminal;
• and
• a control section operatively associated with the HVACR system for selectively activating or deactivating the at least one evaporator coil based on one or more settings received from the at least one remote controller terminal via the communications section;
• wherein the method comprises providing a coil treatment to the at least one evaporator coil, such that the use of the controller in conjunction with the coil treatment reduces the energy usage of the HVACR system by over 15%;
• wherein the coil treatment comprises:
• i) a first enzymic cleaning step comprising contacting the coil with an enzymic cleaning solution to provide a cleaned coil;
• and
• ii) a second step comprising coating the cleaned coil with a biostatic polymeric coating;
• wherein the enzymic cleaning solution comprises one or more enzymes, a biocidal quaternary ammonium biocide, and an anionic hydrotrope.

• a polyvinylpyrrolidone/polyvinylacetate copolymer complexed with triclosan;
• or
• a quaternary ammonium biocide and a compatible polymer, such as polyvinyl alcohol, or a half ester of maleic anhydride/alkylvinylether copolymer complexed with a quaternary ammonium biocide.
