Gree Condensate Pump Wiring

If you are experiencing difficulty wiring Gree ductless mini-split units to the condensate pump, the below instructions will help you.

Problem:

Code E6 communication failure upon commissioning. L1 and L2 (condensate pump) are wired to N(1) and 2. Terminal 2 is DC communication between the outdoor unit and the indoor head.

Solution:

Wire L1 and L2 (condensate pump) to N(1) and 3. Reference image above. We sell the Diversitech Clear Vue Mini condensate pump but any other condensate pump will work.

Conclusion:

Once the wiring is connected correctly, the system operates normally, the pump will cycle and the end-user will be satisfied.
