A central vacuum cleaning system can include a vacuum unit, a plurality of inlet valves, an exhaust, a cleaning air path from the inlet valves through the vacuum unit to the exhaust, and a control unit. An example control unit can include a power input, a power output, motor control circuitry to control application of power from the power input to the power output, a first port, a second port, a conduit providing a conduit air path between the first port and the second, a heat sink in thermal contact with the conduit air path and a component of the motor control circuitry, wherein the control unit is connected through the first port and the second port in the cleaning air flow path between the inlets and the exhaust, and the power output is connected to a power input of the vacuum unit.

Central vacuum control unit

Sensor includes electrodes on internal layer of multilayer printed circuit board, and sensing circuitry drives electrodes and reads signal having characteristic based upon capacitance between electrodes. Board may have first layer second layer, with electrodes between layers. One layer may be thicker than other layer such that capacitance external to board is primarily contributed from adjacent other layer. Electrodes may be on internal surface and sensing circuitry may be on opposing external surface. Components for sensing circuitry may be assembled to board such that board and components are multilayer printed circuit board assembly. Circuitry having wireless transmitter and wireless receiver, wherein circuitry has operating mode to transmit signals remotely through transmitter and ship mode wherein transmitter is silenced, and in operating mode circuitry listens for signals indicating transmitted signal has been received, and if receiver has not received acknowledgement one signal then circuitry enters ship mode.
