Estimating the term…
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.
A method of controlling a heating, ventilation, and air conditioning (HVAC) system using a HVAC control system, comprising the steps of
A heating, ventilation, and air conditioning (HVAC) control system for controlling an HVAC system, comprising a processor, wherein when the HVAC control system is initially powered, said processor reads a default memory location within said processor, and wherein the contents of the default memory location direct said processor to a Basic Input/Output System (BIOS) Erasable Programmable Read Only Memory (EPROM) associated with the control system;
A method of controlling a chiller with a heating, ventilation, and air conditioning (HVAC) control system, comprising the steps of
A heating, ventilation, and air conditioning (HVAC) control system for a chiller, comprising:
The HVAC control system of 37, wherein the plurality of parameters includes at least about 14 parameters.
