The apparatus includes a first triac having terminals to which the control wire of a heater gas inlet valve solenoid or other heating element is connected and the apparatus further includes a second triac to which the control wire of an air conditioner compressor or other cooling element is connected. The triacs are actuated by respective optical coupling devices. One or the other of the optical coupling devices is selected by a switch to indicate whether the heater or air conditioner mode is selected. Whichever optical coupling device, and thus whichever mode, is selected, a timer circuit provides a selectable timing signal to cause the selected optical coupling device to periodically actuate or deactuate the associated triac to thereby activate or deactivate the solenoid or compressor (or other element) associated with the triac.
