Abstract

See full text

A controller for use in a climate control system includes a power stealing circuit connectible with a control of the climate control system and configured for stealing power via a signal from a power source through the control. An overcurrent limiting circuit is configured to limit a first portion of the signal to prevent a false call for operation of the control. The overcurrent limiting circuit is further configured not to limit a second portion of the signal to prevent a false call, where the control is configured to recognize only the first portion as determinative of whether the signal is a call for operation.
