Abstract
Methods for controlling an economizer of an HVAC system are disclosed. An illustrative control method may include positioning one or more controllable dampers in first and second configurations such that a mixed air stream has first and second mixing ratios of incoming outside air to return air. First and second measures related to the temperature of the mixed air stream may be recorded when the dampers are in each of the first and second configurations. Based on the recorded first and second measures, it may be determined whether and/or how much of the incoming outside air to admit into the economizer via the one or more controllable dampers during subsequent operation of the HVAC system.
