Nest Power Connector
The Power Connector functions as a solid-state power bridge installed at the HVAC control board, providing a constant 24VAC path that the thermostat requires to maintain its internal battery charge. This eliminates the 'power stealing' behavior where the thermostat pulses the equipment relays, which often leads to insufficient charging and unintended system short-cycling. It serves as a non-invasive alternative to pulling a physical C-wire through the building's infrastructure.
