Abstract:
A microprocessor-based, DC powered control system for heating or cooling system comprising an interconnected series of microprocessors, wherein the series of microprocessors comprises at least one of each of: thermostat microprocessor; zone valve microprocessor; and boiler circuit microprocessor,wherein the at least one thermostat microprocessor quantifies one or more room temperatures and one or more user-defined set temperatures in a zone, communicates the one or more room temperatures and the one or more user-defined set temperature to the at least one zone valve microprocessor, and sends the one or more room temperatures and the one or more user-defined set temperature to at least one boiler circuit microprocessor; wherein the at least one zone valve microprocessor controls position of at least one zone valve based on the one or more room temperatures and the one or more user-defined set temperatures, and sends information regarding the at least one zone valve position to the boiler circuit microprocessor; and wherein the at least one boiler circuit microprocessor operates at least one selected from the group consisting of a stack damper, circulator pump, and gas valve.
