Abstract

A unitary control module having adjustable input and output mapping functionality, including methods of configuring such devices for use in different applications, are disclosed. The unitary control module can include a unit type selector such as a DIP-switch that can be used by an installer to configure the control module to emulate a particular type of controller. The control module can be configured to run a selection algorithm for configuring the mapping of the input terminals and output terminals for the device based on the controller type selected. In use, the control module may run different control algorithms for controlling the system components based on the controller type selected.

a unit type selector for selecting between a number of controller type settings; and

a controller having stored therein a plurality of configurations for a plurality of controller types, wherein the configurations include algorithms, the controller configured to run a selected algorithm for configuring the input terminals and/or the output terminals based at least in part on the selected controller type setting.

2. The control module of claim 1, wherein the control module is configured to automatically detect the connection of the humidity sensor or adjustment potentiometer to the setpoint input terminals.

7. The control module of claim 1, wherein the controller is configured to run a different control algorithm based on the controller type setting selected via the unit type selector.

8. A unitary control module configured to selectively emulate a plurality of different controller types, comprising:

an input interface having one or more input terminals;

an output interface having one or more output terminals, wherein the output interface includes an analog output interface and a relay output interface;

a unit type selector for selecting between a number of controller type settings; and

a controller having stored therein a plurality of configurations for a plurality of controller types, wherein the configurations include algorithms, the controller configured to run a selected algorithm for configuring the input terminals and/or the output terminals based at least in part on the selected controller type setting.

9. A unitary control module configured to selectively emulate a plurality of different controller types, comprising:
