Some embodiments comprise irrigation controllers, comprising: a first set of functional inputs with each functional input of the first set of functional inputs exclusively corresponding to a first language; and a second set of functional inputs with each functional input of the second set of functional inputs exclusively corresponding to a second language that is different that the first language; wherein each of the functional inputs of both the first set of the functional inputs and the second set of the functional inputs are available for activation by a user at the same time, and wherein each function correlated with one of the functional inputs of the first set of functional inputs is also correlated with a corresponding one of the functional inputs of the second set of functional inputs.
