Configurable HVAC controller terminal labeling

A system having a configuration tool for configuring a programmable HVAC controller having a plurality of configurable I/O terminals, the configuration tool comprising:

• a user interface;
• a controller including a processor, the controller in communication with the user interface, wherein the controller is programmed to accept user input from a user via the user interface, wherein the input relates to characteristics of a particular HVAC system to be controlled by the programmable HVAC controller, and based on the accepted input from the user, generate a corresponding configuration profile, wherein the configuration profile, once loaded into the programmable HVAC controller, causes the programmable HVAC controller to assume a particular controller configuration that is suitable for controlling the particular HVAC system, with each of at least some of the plurality of configurable I/O terminals of the programmable HVAC controller assigned to a particular I/O function that is tailored to controlling the particular HVAC system;
• an interface in communication with the controller, wherein once the configuration tool is connected to the programmable HVAC controller, the controller can download the configuration profile to the programmable HVAC controller via the interface;
• and
• the controller further programmed to generate a terminal diagram that labels at least some of the plurality of configurable I/O terminals of the programmable HVAC controller with the assigned particular I/O functions that are defined by the configuration profile.
