Russ here. Sorry about wait. Getting ready for Hurricane Irma. The fan speed has to be setup in the air handler or furnace. Is this a two stage system. Can you give me model numbers of outside and inside unit. Russ
Yes it made sense. Do you just have one thermostat for the house. Russ
What is happening since you are just sometimes cooling the bedroom the ducts are handling more air than they need to at times. The installer should have installed a bypass damper to take care of the problem. The by pass damper opens and closes to allow the static pressure of the duct to remain the same. Check with installer and see if damper was installed. Russ
Can you get the model number of the air handler inside . I can adjust fan speed from there. Russ
Furnace in the Garage.
Thanks. Pulled manual on system. Dip switches in air handler can be set up for low fan speed . Sounds like the fan speed is set at 400 CFM. Also I did not see a bypass damper in system. This would assure you that you would not have a blast of air like you are getting. Can you contact installer and see if he installed a bypass damper. Russ
Yes just get back with and I will walk you thru it. Rating is open. Russ
