Hi! Thank you for your query about the DIAL 7617 digital thermostat. According to the installation manual, the green wire is for the ground connection. The ground wire will not be connected to this thermostat. You can connect the ground wire from your evaporative cooler going to the circuit breaker. You may check this installation manual for the electrical diagram and as a reference for a proper wiring connection. We hope this helps. Thank you for trusting PlumbersStock. Have a great day!

Hi! Thank you for asking about the dial 7617 controller thermostat. The ground wire must install a return (Common, or L2) wire from your cooler to this cooler controller junction box, not the model 7617 Cooler Controller. You may check this installation for more instructions. Thank you for trusting PlumbersStock. Have a great day!
