The proposition $p$: The real number $x$ satisfies $x^{2}-5ax+4a^{2} < 0$ (where $a > 0$), and the proposition $q$: The real number $x$ satisfies $(x-2)(x-5) < 0$.
(1) If $a=1$, and the proposition "$p∧q$" is true, find the range of values for the real number $x$;
(2) If $p$ is a necessary but not sufficient condition for $q$, find the range of values for the real number $a$.
