I'm having problems about the room temp, also I want to know the correct way to set the amps. When I opened the thermostat, there's 1.5 amp to 3 on the left side and 2.5 on the right side. What is the correct way to point the adjustor switch to let the A/C running and to let not the A/C to keep running forever? at the moment I go back and forth to 4 & 3. Is this correct? The temp in our room is not as cold/comfty compared in to our lving room. We live in a condo. Thank you.
