A relatively simple status indicator for a building control device that helps the user more quickly and intuitively identify the operation status of the building control system and more quickly troubleshoot faults and/or other problems that may occur within the building control system. This may help reduce the cost of maintain the building control system and may help reduce unwanted downtime of the building control system.

The present disclosure relates to a user interface module for a building control system that has flexible mounting options to address mounting constraints that are often encountered in utility rooms and/or equipment panels. In some cases, the user interface module may be provided with interchangeable mounting bases from which an installer can select depending on the mounting constraints presented at a particular installation.

A rotor assembly may include first rotor half, a first spring supported with the first rotor half, a second rotor half, and a second spring supported within the second rotor half, wherein the first rotor half and the second rotor half are adjoined to enclose the first and second springs. A coiled section of each spring may surround a rotor center pin. A contact arm positioned between the springs may include a non-circular opening. A method for assembling such a rotor assembly is further described.
