A controller for the power supply system of a building structure divided into multiple zones provides a time-programmer and a load shedder for controlling the availability of separate heating, ventilation, and air-conditioning apparatus for individual zones and the separate apparatus associated with the building and includes switches for overriding the time programmer to allow selected apparatus to operate at will for a short period. The controller includes thermostats monitoring the temperature in the zones and operating the HVAC apparatus during certain temperature conditions, a meter for displaying the monitored temperature, and switches for selectively disconnecting the thermostats from the respective zone apparatus and connecting them to the meter while simultaneously connecting a dummy resistor to the respective zone apparatus in lieu of the thermostat. Hour meters and counters on the controller panel monitor and indicate elapsed running time and number of cyclings for certain elements of the apparatus, and signal lights indicate the operating status of certain elements.
