Abstract

An apparatus (10) for monitoring and controlling a heater zone having at least one heater element (14) comprises a switching device (22) coupling the heater element to a power source (16) and actuable to allow power to be supplied to the heater element. A current sensing device (30) senses current supplied to the heater element when the switching device is actuated. A controller (24) is coupled to the switching device and the current sensing device. The controller signals and alarm condition (SA) when current drawn by the heater element deviates from normal operation and adjusts actuation of the switching device to compensate for the deviant heater element operation.
