Claim:
1. A compact thermostat, comprising: a head unit having a circular exterior front surface and a first connector, wherein the circular exterior front surface comprises: a rotatable ring disposed around the circular exterior front surface; a back plate comprising a second connector, wherein the first connector is coupled to the second connector; the electronic display mounted within the head unit and viewable through at least a portion of the circular exterior front surface, wherein said electronic display comprises a non-circular dot-matrix color display element, said circular exterior front surface having a clear circular center portion and an opaque outer portion, the clear circular center portion permitting a corresponding circular portion of the non-circular dot-matrix color display element to be visible therethrough and the opaque outer portion masking a remaining portion of the non-circular dot-matrix color display element so as to create a circular visual appearance for the electronic display, wherein said thermostat further comprises: a printed circuit board within the head unit, wherein the printed circuit board comprises a wireless communication circuit that couples the compact thermostat with a network; a cavity located between the printed circuit board and the circular exterior front surface; a daughter circuit coupled to the printed circuit board comprising: a second temperature sensor positioned within the compact thermostat in a location separated from the first temperature sensor and positioned differently relative to one or more heat generating components mounted to the printed circuit board, wherein the calculation of ambient temperature is based at least in part on measurements from both the first temperature sensor and the second temperature sensor.
