Abstract
Provided is an electrical device. In a setting unit, a right-room temperature display unit displays a set temperature or the current temperature of a first housing room. A left-room temperature display unit displays a set temperature or the current temperature of a second housing room. A right-room temperature setting button is an operation unit for a user to switch the set temperature of the first housing room. A left-room temperature setting button is an operation unit for a user switch the set temperature of the second housing room. The set temperature difference between the first and second housing rooms is controlled to be within a prescribed value. When the set temperature of one of the first and second housing rooms is changed so that the set temperature exceeds a prescribed value, a microcomputer automatically changes the other set temperature so that the set temperature difference is within a prescribed value.
