Abstract
The present invention includes devices and methods for power sharing for a lower voltage programmable thermostat for operating a switch which operates at a substantially higher voltage. The present invention is preferably applied to two power line thermostat control of HVAC equipment. It is intended that the present invention be applicable to other such devices where power is stored by capacitance or in rechargeable batteries for use by lower voltage programmable thermostats while at the same time permitting sufficient current flow through a substantially higher power switch to operate directly or indirectly electrical power equipment.
