1. A dialysis machine comprising:
- a control unit having a user interface;
a heater located separate from the control unit;
a supervisory processor located with the control unit;
a delegate control processor located with the heater, the delegate control processor in communication with the supervisory processor and configured to receive a heater temperature sensor input; and
a programmable sub-delegate heater processor which reads information stored on at least one memory device, the sub-delegate heater processor in communication with the delegate control processor and configured to control power to the heater using the information stored on the at least one memory device in response to a command that is (i) received from the delegate control processor and (ii) generated based upon the heater temperature sensor input.

Abstract
A dialysis machine includes a control unit having a user interface; a heater(s) located separate from the control unit; a supervisory processor located with the control unit; a delegate control processor located with the heater(s), the delegate control processor in communication with the supervisory processor and configured to receive load cell, heater(s) plate and supply bag temperature sensor inputs; and a sub-delegate heater(s) processor in communication with the control processor and configured to control power to the heater(s). The machine can also include primary and secondary monitoring processors that perform a safety check to the control processing and monitor the load cell.

15. A dialysis machine comprising:
-
a control unit having a first housing, the control unit including a user interface and at least one processor; and a heater unit having a second housing, separate from the first housing, the heater unit including a heater/sensor subassembly and a processor subassembly, each subassembly including at least one processor, the heater/temperature subassembly further including a heater and a temperature sensor, the at least one processor of the control unit electrically connected to the at least one processor of the processor subassembly, the subassemblies connected via heater power and signal wires, the processor subassembly connected to the control unit via data transmission lines and power supply lines only, the at least one processor of the heater/sensor subassembly programmed to control the heater by reading information stored on at least one memory device in response to a command that is (i) received from the at least one processor of the processor subassembly and (ii) generated based upon a reading from the temperature sensor. - View Dependent Claims (16, 17, 18)

19. A dialysis machine comprising:
-
a primary control processor; a secondary control processor in communication with the primary control processor and programmed to accept a desired temperature command from the primary control processor; a temperature sensor configured to input a sensed temperature input to the secondary control processor; and a heater processor programmed to operate a heater by reading information stored on at least one memory device, the secondary control processor programmed to send or activate heater commands to the heater processor upon accepting the desired temperature command if a desired temperature of the desired temperature command is greater than an actual temperature of the actual temperature input, the heater processor configured to operate the heater using the information stored on the at least one memory device in response to a command that is (i) received from the secondary control processor and (ii) generated based upon the temperature input. - View Dependent Claims (20, 21)
