Definitions

  • This invention is in the field of energy management systems and more particularly a system for managing a large number of separate heating and cooling devices at separate locations.
  • Figure 4 is a timing diagram of one embodiment of the circuit of Figure 1;
  • the purpose of this process is to periodically, nominally every four minutes, read the analog input of station zone temperature thermistor 74, convert it to a digital value via successive approximations, convert that value via a look-up table and save the result in a set of the three latest converted values.
  • station 150a of Figure 8 When the station control microcontroller- restarts from a power down condition, station 150a of Figure 8, the process of Figure 9 first goes into state 1, initialization, stage 252 wherein the locations reserved for the last three converted values of zone temperature are cleared to zero. As soon as initialization is complete the process proceeds to state 2, convert, stage 254, wherein the process rapidly accomplishes a successive approximation A/D (analog to digital) conversion of the analog station zone temperature input.
  • the successive approximations algorithm is a well known technique for performing an A/D conversion using a microcontroller, a DAC (digital to analog converter) and a comparator all of which are in said station control and need not be described in detail here.
