A pager-based controller including at least one pager configured to receive a signal from a remote location, the at least one pager being further configured to provide an output to change an on-off state of an external electrical component; a heater unit and a fan unit to maintain a predetermined temperatune range within the pager-based controller; a power supply for supplying a required AC voltage and DC voltage to electrical components within the pager-based controller; a latching relay electrically connected to the at least one pager; an interface unit electrically connected to the at least one pager and the latching relay, the interface unit configured to receive the output from the at least one pager and supply a corresponding signal to the latching relay; the latching relay including at least one normally-open contact and at least one normally-closed contact, for providing one of an open and a closed circuit to the external electrical component in response to an energization state of a coil within the latching relay; and a timing relay having a contact electrically connected in series with the output of the at least one pager to eliminate spurious signals from the at least one pager during a power-up operation.

1. A system for controlling the on-off state of a remote electrical device comprising:a pager-based controller; and a terminal for transmitting a signal to the pager based controller; wherein the pager-based controller comprises a housing; at least one pager positioned within the housing and configured to receive a signal from the terminal, said at least one pager being further configured to provide an alarm output to change an on-off state of an external electrical device; and a time delay relay having a contact electrically connected in series with the alarm output of the at least one pager, said time delay relay operable to prevent the pager from changing the on-off state of the external electrical device for a predetermined time period during a power-up operation of the pager-based controller.
