 Change Log:
-v2.7   34/02/17 Fix USA apparent power readings (assuming 110VRMS when no AC-AC voltage sample adapter is present). Fix DIP switch nodeID config serial print if node ID has been set via serial config
+v2.8   27/02/17 Correct USA voltage to 120V
+v2.7   24/02/17 Fix USA apparent power readings (assuming 110VRMS when no AC-AC voltage sample adapter is present). Fix DIP switch nodeID config serial print if node ID has been set via serial config
 v2.6   31/10/16 Add RF config via serial & save to EEPROM feature. Allows RF setings (nodeID, freq, group) via serial
 v2.5   19/09/16 Increase baud 9600 > 115200 to emonesp compatiability
 v2.4   06/09/16 Update serial output to use CSV string pairs to work with emonESP e.g. 'ct1:100,ct2:329'
