38. A backup device for a heating or cooling apparatus temperature controller, the backup device being capable of a plurality of modes of operation and comprising:
-
a temperature sensor;
sensor input means for receiving temperature data sensed by said temperature sensor;
a microprocessor board operable to automatically control a heating or cooling apparatus temperature controller responsive to timing data and to temperature data received by said sensor input means;
a power supply and power switch;
a mode switch for enabling selection among said plurality of modes of operation;
display means including a circuit board and a display screen; and
an output power relay operable to supply or terminate power flow to a heating or cooling apparatus temperature controller responsive to commands received from said microprocessor board, wherein said microprocessor board initiates at least one of a plurality of functionally different operational sequences when the backup device is in a run mode of operation in which the backup device controls operation of a heating or cooling apparatus temperature controller pursuant to heating or cooling process control parameters established by a user, said functionally different operational sequences being selected from the group consisting essentially of;
a start delay sequence wherein said microprocessor board commands said output power relay to supply power to a heating or cooling apparatus temperature controller following a finite period of time selected by a user;
a heating or cooling apparatus test sequence wherein the function of a heating or cooling apparatus is determined by sensing a predetermined temperature change in a medium in a predetermined period of time;
a heating apparatus warm up sequence or cooling apparatus cool down sequence wherein the sensed temperature of a medium must achieve a predetermined temperature in a finite period of time; and
a heating apparatus heat sequence or cooling apparatus cool sequence wherein a medium is heated or cooled for a finite period of time within a predetermined temperature band. - View Dependent Claims (39, 40, 41)
