I just got installed the new Trane XL16i 4 tons about 6 days ago. Following are the problems that I am having:
- Excessive moisture outside air-handle
- constant cooling cycle even already change option 220 and 230 from the thermostast TCONT900AC43UA
- The dealer update system from 3 ton to 4 ton without do air balancing
- The vent direct hit the thermostat made the system shutdown fast
The most concern is why too much moisture developing outside the air-handle?
Does anyone have experience on Trane 4TEE3C07A1000A (air handle), 4TTX6 (outside unit), and TCONT900AC43UA (thermostat)?
How do I measure the CFM at the register? The dealer said it should be right but the register was designed for 2.5 tons when the house had not modified.
There are 4 settings for Airflow Performance on air-handler (290 CFM, 350 CFM, 400 CFM, and 450 CFM). The current setting is 400 CFM for 4 tons. If change it to 350 CFM is it means the system will run as 3.5 tons and 290 CFM is 2.9 tons. Will the cycle is going to be longer if decreasing the CFM?
