WIRING DIAGRAM

485 Communication Function Instruction

When the 485 communication distance is more than 300m, need to increase terminal resistance in 485 the beginning of the communication terminal and end Especially, if the communication equipment quantity is less in the trunk(less than 22pcs). When increasing terminal resistance, only short circuit the terminal resistance jumper J5 of the thermostat.
Remote Control Optional
