Abstract

A control system is disclosed for use in a restaurant having a forced air input air conditioning and/or heating system and a grill with an exhaust fan operating therewith. The invention includes an exhaust fan sensor means for monitoring the operative condition of the exhaust fan. A grill control means is provided for controlling the on/off operation of the grill. An air input sensor means senses the operative condition and the air flow of the air conditioning and/or heating system. A controller is connected for monitoring the sensors and for inhibiting operation of the grill upon an inoperative condition of the exhaust fan. The controller further inhibits operation of the air conditioning and/or heating system upon an inoperative condition of the exhaust fan thereby insuring the correct temperature within the restaurant. The invention may optionally include a stand-by power supply, a line voltage monitor and programmable thermostatic controller. An optional automatic telephone dialer may be connected to the controller for providing communication to a remote location of the inoperative condition of the system. The foregoing is merely a resume of one general application, is not a complete discussion of all principles of operation and applications and is not to be construed as a limitation on the scope of the claimed subject matter.
