HVAC Fan

redlightning

i have an HVAC system with the Passport control system.  My question has to do with the fan.  When setting a temp with the heat or cooling, is there a way to have the fan stop at some point after reaching the desired temp.  Cycling on and off as needed when cooling or heating.  Now the fan seems to stay on regardless if the system is heating or cooling.

Yes, you can program it to cycle on and off. You need the manual and get the unit into programming mode to change it.

By default, the fan turns off when not heating/cooling.  Somebody must have changed your settings to constant-on.  I do that sometimes when I want a constant sound level when sleeping overnight.

According to the manual, the fan is supposed to be continuous by default while in cooling/heating mode. I know that mine is continuous when the Air/heat is on and only shuts off when the system is off.

yes, continuous is default.  The reason is because the cycling of the motor/fan will wear it out quicker than just leaving it on.

Thanks 
I thought the way I read the manual indicated it should cycle off.  I have not tried it with the heat yet, but after changing the setting a few weeks ago, it didn't seem to cycle off when the compressor would cycle off when cooling.

sorry wrong thread.

As others have said it's in the programming. Download the vendors manual to find out how to that

yep, programming.  I went to check the heater today since it will be 25 tonight.

checked the program and I guess I didn't save the programming change when I changed it earlier in the season.

Thanks for all the feedback
