Low-cost controller having a dynamically changeable interface
First Claim
1. A single HVAC zone controller for dynamic redefinition of a short stack initialization-comprising:
- a first processor connected to a network; and
a second processor connected to the first processor, wherein the second processor is connected to the network via the first processor; and
wherein;
the first processor comprises;
a communication interface; and
a first network variable memory having a first set of network variables; and
the second processor comprises;
a control logic module connected to the communication interface;
a second network variable memory connected to the control logic module and the first network variable memory; and
the communication interface provides a second set of network variables to the control logic module;
the control logic module provides the second set of network variables to the second memory; and
the second memory has contents flashed into the first memory such that the second set of network variables replaces the first set of network variables.

Abstract
A controller for dynamic redefinition of a short stack initialization to provide a low cost generic controller. The controller may be built with a network variable interface which has its variables initially selected by the time of the completion of the build. Thus, if different network variables are desired, then the controller needs to be placed with the builder or special technician for implementing the changes. The present invention modifies that controller so as to provide a capability of changing the network variables without the need of the builder or anyone else to modify the network variables in the controller'"'"'s interface. The network variables may now be changed by an operator or customer, even while that controller is in operation.
