Both the G & E series have capabilities to do so. 

  • The E series has G2 wire already set from TAP 1 of Fan Motor to CN7 on Main Control Board (Can come on CN8 by mistake from factory, please advise to move to CN7) and from there follows in to CN9 (which is the  terminal for the themostat wires) that translates  into the wire you connect to the  G2 connection on our Thermostat. 
     
  • While the G series G2 wire needs to be given separately from the factory and is hard wired from the thermostat's G2 connection directly to the motor connection at Tap 1.
