Abstract:
1. A method to control environmental parameters of pre-defined zones within a first environment using a non-proprietary electronic controller, where each of said pre-defined zones has an associated duct work capacity, and where said non-proprietary electronic controller stores a weighting value for each of said pre-defined zones representative of said associated duct work capacity of each of said pre-defined zones, said method comprising: said non-proprietary electronic controller detecting any zone service calls from sensor devices associated with each of said pre-defined zones; said non-proprietary electronic controller transforming said detected zone service calls and said weighting value of each of said pre-defined zones associated with said detected zone service calls into a cumulative zone weighting value representative of a cumulative duct work capacity of said pre-defined zones associated with said detected zone service calls; said non-proprietary electronic controller selecting an air handler stage from at least two possible air handler stages in response to at least said cumulative zone weighting value; and said non-proprietary electronic controller activating said selected air handler stage.
