E2  Setup

Connect the network cable to the three-terminal connector on the COM port that has been configured for the 

thermostat. The thermostat polarity markings are the same as E2; connect the thermostat B+ wire to the E2 

RS485 + terminal and connect the thermostat A- wire to the E2 RS485 - terminal. The shield cable should be 

connected to the C terminal.
