Control systems for heat transfer systems, and related heat transfer systems

A control system for a heat-transfer system, the control system comprising:

• a system control logic having a first processor, a first memory, and a first communication connection, the first memory storing first instructions that when executed by the first processor cause the control system to transmit an indication of health of the system control logic from the first communication connection and to control operation of the heat-transfer system;
• and
• a supervisory control logic having a second processor, a second memory, and a second communication connection configured to receive the indication of health from the first communication connection, the second memory storing second instructions that when executed by the second processor cause the supervisory control logic to determine a state-of-health of the system control logic responsive to the received indication of health and, responsive to the determined state-of-health being below a selected threshold state-of-health, to output a command signal to selectively operate the system control logic,
• wherein the second instructions, when executed by the second processor, further cause the supervisory control logic to output the command signal from the second communication connection responsive to the determined state-of-health being below a threshold state-of-health,
• wherein the first communication connection is configured to receive the command signal from the second communication connection and, responsive to receiving the command signal output by the supervisory control logic, the system control logic is configured to re-boot from a boot source external to the system control logic.
