At the heart of the Paloma House is a command-and-control structure where your Paloma Tankless Digital Remote Control awaits your command.
The Main Controller (UMC-117), also known as the Kitchen Controller in residential models, lets you set temperatures in 2-degree intervals between 100 and 120 degrees F. (With professional adjustment of dipswitches in the controller, you can go even higher on some models. However, Paloma recommends never making this adjustment unless you have a specific requirement for doing so � hot water causes serious burns!)
Temperature settings can be changed by touching in new settings at any time, even while the water is running.
A Main Controller should be installed in the kitchen, laundry room or near the Paloma itself (but never outdoors).
