A first timer operated switch is in circuit with temperature responsive switching means and space conditioning apparatus control means and is operative to alternately control operation of the space conditioning apparatus control means at one and then the other of two different levels of temperature. A second timer operated switch is in circuit with the space conditioning apparatus control means and with circuit means for recharging the battery and is cyclically actuated to an open position to ensure complete de-energization of the space conditioning apparatus control means and to a closed position to enable the battery to be recharged.
