Abstract
A condition responsive time proportional control means which has a relatively fast time constant when operating in its proportional band has the time constant expanded by means of a digital counter. The counter is a resettable unidirectional type counter that has two counting channels. The main counting channel provides for the counting function during the normal cycling of the system when in the proportional band. A second channel in the counter acts to enable to the counter rapidly in the event that there is a disruption of the counter when the condition responsive system has been outside of the proportional band.
