Power transformation self characterization mode

A self calculating load test mechanism comprising:

• a heating, ventilation and air conditioning (HVAC) load selected for calculation;
• and
• a load test run on the HVAC load upon meeting predetermined conditions indicated by a thermostat control circuit;
• and
• thermostatic control of the HVAC load is disabled when the load test has started;
• and
• wherein:
• if a call for heat or cool is made at the thermostat, a response to the call is delayed until the load test is completed, and if AC power is lost during the test, the test may finish and allow AC detection of the phantom AC detection device with a loss of AC power;
• and
• if a voltage of a storage capacitor falls below a battery boost threshold (BBT), the test is cancelled to allow the phantom circuit charge the storage capacitor to a predetermined value for the test.

A method for load calculation comprising:

• setting up a test arrangement with a charge current source for charging;
• connecting for measuring a load of an HVAC;
• connecting a charge percent circuit to the charge current source;
• setting a charge percent rate of the charge percent circuit to zero;
• taking a baseline voltage measurement;
• setting a charge percent until a charge rate is equal to or greater than a predetermined value;
• taking a voltage measurement where the baseline voltage measurement was taken;
• and
• calculating a voltage across the load of the HVAC from a difference of the baseline voltage and the voltage measurement when the charge percent of the charge percent circuit is equal to or greater than the predetermined value.
