We prove a criterion for Klein four symmetric pairs $(G,G^\Gamma)$ satisfying the condition that there exist infinite-dimensional simple $(\mathfrak{g},K)$-modules which are discretely decomposable as $(\mathfrak{g}^\Gamma,K^\Gamma)$-modules. Making use of the criterion, we classify all the Klein four symmetric pairs satisfying the condition for the exceptional Lie groups of Hermitian type: $\mathrm{E}_{6(-14)}$ and $\mathrm{E}_{7(-25)}$.
