A priority protocol is provided with respect to the SET and RESET functions. The circuit of the controller is housed within a circuit housing which includes a polymeric seal and operates in conjunction with a sealed keypad. This circuit housing is incorporated within a principal housing and a positive pressure is maintained within that principal housing to assure the integrity thereof.
