How To Change The Fan Speed On A Carrier Thermostat

i take a carrier 58MVP infinity heat/absurd unit that has been on line for ii months and i want to lower the continous fan speed like to that which a friend has on his 5 yr onetime 58MVB unit....when my unit is on AC, the blower actually rolls and cools the business firm....when it hits the set point, it switches to coninuous fan as it is set upwards to practice....but, the drop in air movement is like from 100% on Air-conditioning down to 85% on continuous fan....my friend's unit goes from 100% on AC downwards to 15% on continuous fan....the local Carrier Distributor put both in and does has looked at my unit and says that he does not know how he could lower the fan speed or if it tin can be done.....thinks that mayhap my friend's unit drops so much because it is a larger unit of measurement and business firm....both seem very comparable air movement, speed and noise on AC....i guess the big question is..."Can the 58MVP continous fan speed exist adjusted?????,,if so, how?????..."....whatsoever inf on this would be appreciated...if the continuous fan speed could be lowered like to my friends unit, this would be a very good organization.

Do you have the Infinity control?

I thought my sales guy was handing me a line when he said he wouldn't purchase the furnace without the upgraded thermostat. After I thhought about it, I figured information technology wasn't also large of a toll to pay for the added comfort I'd get.

After 9 months with information technology, I highly recommend it.

I can suit my humidity in both winter and summer. It allows me to adjust the constant-on fan speed. It obviously has the usual set-back features. Plus, you can see fault codes, run times, cycle counts and static pressure level. Information technology tells y'all when to change your air filter based on static pressure level. A feature I actually like is the Smart Recovery. I tell it I want my home to be 72 in the wintertime when my family comes home and information technology measures the electric current temp and adjusts the time it will come on so it volition be 72. No guessing by me, merely pure comfort.

If you lot already shelled out the bucks for the furnace and mayhap fifty-fifty the Air-conditioning, practice yourself a favor and get the T-stat.

End running the fan continuously, especially in the cooling season, you are bringing a lot of the moisture that gets removed from the air right back into the home during the off cycle.

Sorry, but air moving doesn't create water.

The only style your air tin can exist humid, is if information technology is actually already boiling. Or are you proverb that the fan is pushing water off the curlicue back into the firm? If that'southward the case, why wouldn't it simply drip down the condensate line like it does when the unit is on? The coil isn't cold forever, the time it would take it to cool down and not be an issue would be relatively short. No?

Where would the additional water vapor come from?

i don't understand how information technology generatres more than wet either...can y'all explicate????.....as for the T-stat, my guys don't sympathize information technology all the same...they merely ordered one in to try to acquire it....yes, i live in the sticks.....but i had heard that the new T-stat would requite me control over "a lot of things" and will see if my guys accept the new one in and if that is a mode to exist able to control the speed...especially if it generates humidity....

Doesn't the fan button give yous low, medium and loftier speeds to choose from?

Mine is in the upper correct hand corner of the Infinity command. Small button. Low/Med/Loftier/Machine

When the system shuts off the evaporator is yet moisture, and at that place is water standing in the drain pan, with the fan on this moisture evaporates rapidly and is carried dorsum into the conditioned space.

In a properly installed arrangement, how much water sits in the pan? Seems like you'd take more left in the bathroom, in the tub and on the walls and mirror than in the pan.

Simply, I'm non a pro, just a homeowning guesser.

If you do not take an Infinity Control And just a standard thermostat, you could toggle the fan off then on 3 times. You should hear the fan first to ramp up.

xgpcer,

I have the 58MVP as well. There are dip switches in the furnace that need to exist ready correctly for continuous fan speed. Did your installer look at them?

What size of furnace is yours? Mine is a 58MVP-060 (threescore,000 BTUs). Different size furnaces accept different settings bachelor on the dip switches.

The dip switch settings can frequently be overlooked. Mine was not set correctly by my installer, so I adapted them myself.

Too, if you lot take a more contempo MVP furnace (seventy series or college), I really recommend getting the Infinity Control. I used to accept the Thermidistat control on mine, simply the Infinity is SO much better. You can accommodate the fan speeds very hands from the control. Absolutely get the Infinity Control, believe me, you lot'll love it! You lot don't have to worry nearly the dip switches either as everything is setup from the control and the dip switches aren't used anymore.

Regards,
Ken

Not sure if this will work simply I think some Carrier furnaces like the STA MXA or CVA you can change the cont fan speed by switching the fan switch at the Thermostat from ON to Machine and Back to on and tis will change cont fan speed. Y'all need to practice it quickly or the speeds will non change. Not sure if it works with a digital thermostat.

Also check your furnace manual you volition find enough of info in there.

The Carrier MVB is a newer model that replaced the MVP about a year ago. If you have the newer furnace board in your MVP you lot should wait into getting the
Carrier Infinity Controler, its a nice upgrade and works well with the furnace.

OOPS...i accept the 58MVB-060 and my friend has the 58MVP100...my themostat is not an infinty....merely did follow-up on the transmission and the on/off fan and did reduce my continuous fan speed tho i don't know that i got iy all the wat down....no hi,med,low settings tho, just fan on or fan off....i have heard of the famous "dip switches" simply been scared off of trying them and expected my installer to know and adapt...he has been installing them for 16 years.....when initially choosing the furnace, the Bryant guy stated that he would show me how to adjust them if i went with his Bryant...nonetheless sounds like something i should try to get my Carrier HVAC guys to do...thanks ...appreciate the help from all...

From install transmission which you should have:

Continuous Blower Speed Option from Thermostat
To select different continuous-blower speeds from the room
thermostat, momentarily turn off the FAN switch or pushbutton
on the room thermostat for i-three seconds later the blower
motor BLWM is operating. The furnace control CPU will shift
the continuous-blower airflow from the factory setting to the
next highest CF choice airflow as shown in Fig. 47.
Momentarily turning off the FAN switch once more at the thermostat
will shift the continuous-blower airflow up i more than
increase. If you repeat this procedure plenty, you will
eventually shift the continuous-blower airflow to the lowest
CF option as shown in Fig. 47. The choice tin be
changed as many times as desired and is stored in the retention
to be automatically used following a power interruption.
This feature is disabled when blower off delay is ready for 180 sec.

Continuous fan Volition pick water upwards off the ringlet and pan and redistribute into the house. Yes, almost of information technology will eventually drain if the fan is not running, but fifty-fifty in a "properly installed" system, some water volition alwasy sit in the fan.

If you have an Infinity control the dip switches that were mentioned earlier have absolutly no effect on fan speed. The Infinity ignores and overwrites the dip switch settings. If information technology is a standard stat so you tin adjust the dip switches.

If you practice have the Infinity your only constant fan selection is the Low/Med/Hello/Auto select in upper right of control. These fan speeds are set according to what size unit you lot accept and are a percentage of total fan speed, not adjustable. If on low it is still besides much so maybe it is a duct sizing problem that you have as well much velocity on low speed. With Infinity, if you take information technology set to continuous fan it is smart enough to shut the fan downwardly for 5 minutes at the end of the cooling bicycle ( to permit the water drain and not re-humidify) and then come on to continuous speed until next cooling phone call.

I did get ahead and wade through the manual...as a last resort...adjusted the speed via the thermostat and even sorted out the famous "dip switches"....i adjusted the CF dip switches all the way back to the factory default setting and now have as low a speed as the unit can requite for now...not as low as my friend'due south tho....but much improved....and my ductwork is more restrictive just would remember that i could just lower the CF further anyhow....the local Carrier guy said he will encounter if the factory rep can farther reduce the blower...I am not the only person that wants a minimal amount of CF... a number of people that i talked with said they would like to use the CF simply don't because of the dissonance....do capeesh the info

I'm another MVP owner and went the same road--showtime adapted the DIP switches to arrange my wants for continuous fan speed, then eventually got an Infinity control. I would concur with other people who say the Inifinity control is a swell match to the furnace. Carrier did an splendid job on it. Not but is it "nicer", information technology actually does command temperatures better than the dumb "on/off" controller that was originally installed with my new system. If you have an Infinity furnace, get the Infinity control.
