    Abstract: Systems and methods are described for synchronizing an HVAC control system. A method, includes: a synchronization sequence including: reading a base time from an internal clock at a first time and saving the base time; measuring an elapsed time interval, from the first time to a second time, by counting an external clock using a frequency counter; and then resetting the internal clock to the base time plus the elapsed time.

    Abstract translation: 描述了用于同步HVAC控制系统的系统和方法。 一种方法,包括:同步序列,包括:从第一时间从内部时钟读取基准时间并节省基准时间; 通过使用频率计数器对外部时钟进行计数来测量从第一时间到第二时间的经过时间间隔; 然后将内部时钟重置为基准时间加上经过的时间。
