PART 2: HOW THE MUNCHKIN CONTENDER OPERATES (CONT’D)

Super Stor Ultra Indirect Water Heater to get a fast recovery by prioritizing the flow at a higher temperature than may be needed for the central heating circuits (this will require two separate circulators). You must follow the piping, wiring and programming instructions

located in the Vision One section of this manual. Optional kit consists of the following

•Outdoor sensor – 7250P-319

•Indirect tank sensor – 7250P-325
