A system and process for loading control software into the control panel of a liquid chiller system is provided. A PCMCIA card socket is installed on a circuit board of a liquid chiller control system and is in direct connection with microprocessor data and address buses. A linear flash PCMCIA card having new control software for the control panel is inserted into the PCMCIA card socket when the control panel is de-energized. The control software from the PCMCIA card is loaded into a flash memory of the control system by software executed directly from the PCMCIA card. The software in the PCMCIA card erases the flash memory of the control system, copies the control software from the PCMCIA card to the flash memory and then confirms that the copy of the control software was successful. After the control software has been copied, the control panel is de-energized, the PCMCIA card is removed and the chiller system is restarted and executes the new control software stored in the flash memory.

System and method for loading software into a control panel for a chiller system

A heating, ventilation, and air-conditioning (HVAC) control system and method for controlling a device, a subsystem, and/or a process using a flash mini-card. Preferably, the present invention is directed to an HVAC control system and method for controlling a chiller and the devices and subsystems associated with the chiller using a flash mini-card. More preferably, the present invention obviates the need for the HVAC control system and method to use at least one of the following: a hard disk, a disk controller, a card reader, or a card controller. The method includes, for example, applying power to the HVAC control system, wherein the step of applying power initiates a boot-up of a processor associated with the HVAC control system; reading a default memory location, wherein the contents of the default memory location direct the processor to a Basic Input/Output System (BIOS) connected to the processor through a bus; configuring the processor associated with the HVAC control system by executing a set of BIOS instructions within the BIOS, wherein after the step of configuring, the processor reads a set of boot instructions that directs the processor to the flash mini-card containing a set of instructions; and performing at least one of the set of instructions contained within the flash mini-card to control the HVAC system using the HVAC control system.
