A wall mountable connector for securing a thermostat to a wall is disclosed. The wall mountable connector may include built in jumper functionality. In some cases, the wall mountable connector may include a plurality of wiring terminals as well as structure enabling an installer or other person to easily electrically connect (e.g. jumper) one or more of the wiring terminals in order to accommodate different equipment installations. For example, in some cases there may be a desire to electrically connect (e.g. jumper) or disconnect certain wiring terminals that correspond to transformer input terminals, which in some equipment installations are intended to be independently powered while in others they are not.
