The ASME construction on this model is the visible end of that, and it is why the same heater turns up on commercial installations and on residential jobs where the owner wanted the heavier build.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe control\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe control system is the part most people notice. Setup, temperature adjustment and troubleshooting all happen at one place, and the two line, 16 character display reports in words rather than numeric fault codes, so a technician is reading a message instead of looking up a table. Pool and spa each get separate control capability, and the heater is equipped for third party remote operation if it is being driven from an automation system.\u003c\/p\u003e\u003cp\u003eThis model is also cataloged as a Lochinvar Copper-Fin2 low NOx heater, so both names point at ERN-302-A.
