| 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 F. (With professional adjustment of dipswitches in the controller, you can even go higher on the 28-R and 28-C Series 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). | ||||||||
