* Default maximum temperature is 120⁰F. Temperature settings of 125⁰F to 140⁰F are available by setting switch #6 to the
ON position on DIPSW1 (upper set of switches).
** Temperatures above 140⁰F will require the use of a MCC-91-2 controller on most models
** NOTE: The C199 commercial model does not require the MCC-91-2 controller for temperatures above 140⁰F.
If multiple controllers are connected to one water heater, all controllers will display the same set temperature.
