Carrier Infinity Control thermostat problem
We just had a complete new Carrier system installed. Top of the line
high efficiency gas furnace (96%) and central air condenser (18 SEER). The thermostat is an Infinity Control model which is supposed to eliminate the hot/cold syndrome of forced hot air heat. Well, it sure as hell hasn't done that. This unit doesn't recognize a change in the room temperature until it's changed by at least three degrees. That means it gets very cold before the furnace kicks on. It stays on for a long time - sometimes twenty minutes or more, then goes off for as long as an hour. It's four degrees outside right now and the furnace came on once in the past hour. When it does go on and off it "thinks" that the inside temp has changed by one degree when in fact the swing is about five degrees. The guy who installed it agrees there is a big problem but he is having trouble convincing Carrier. Does anyone else have a similar problem with this new model? It's very frustrating considering the little sucker cost about $400. Thanks Jane |

Carrier Infinity Control thermostat problem
So your installer doesnt know, what a pro he isnt. Is location same as
old stat, maybe its a poor location or cold wall or bad stat, or getting drafts. Im no pro but am sure it has a settings for temp Swing or Anticipator if it is anything other then your basic cheap stat, it is listed under swing or anticipator settings in your stat manual. Narrow its on off range. Is it a carrier stat. You say 96%, curious what size unit because the only 96% Infinity unit is 38000 input btu from what I saw all other infinitys are around 94.5%, more marketing deception. Is your unit with the VS DC motor designed to be left on 24x7. |

Carrier Infinity Control thermostat problem
Thermostat is in exact same spot as the old one. I'm not sure what you
mean about size. I know next to nothing about furnaces. The quote says "Carrier 58 MVP 96%". Also don't know what a "VS DC" is. It does have a variable speed fan that can be left on all the time at low, medium or high and an auto setting. My installer is going to have someone from Carrier come. He's convinced there's a bug in the thermostat. All I know is we are miserable. |

Carrier Infinity Control thermostat problem
The installer spent about two hours here yesterday. When he first came
he thought we were just some crazy complainers and that it would be fine. Within a short time he realized he was wrong. He had some fancy infra-red thermometers to read the temps in different areas. He saw that the temp would vary by as much as five or six degrees between heat cycles. It may be that he doesn't know how to calibrate it properly. He is having someone from Carrier come. Hopefully they will know more than he does. |

sorry you are having problems, but once they fix it you will be happy. i know the fan motor is expensive to replace, but does save on elec. i leave the fan on low year around. very happy with the system. |

Carrier Infinity Control thermostat problem
What is the "db"?
The problem is the room temp on the thermostat is wrong by about three degrees. The temp in the room has to go down or up two or three degrees before the thermostat sees any change in the temp and reacts. Would the "db" have an affect on the thermostats temp sensor? By the way - the installer came and put in a new thermostat and it did the same thing. He also said he had two other customers with the same problem. He thinks it's a problem with the thermostat. I think it's a problem with the setup. What do you think? |

db , I dont know, maybe he meant sb or set back as in anticipator or
swing, set it to the minimum Swing or Anticipator setting for now till you figure it out. It is in your thermostat manual . Or your " pro" should know the answer on the phone. VS DC is variable speed direct current, you have it. Learn about it. 96% efficient no, I bet yours is only 94-94.5% efficient, just BS marketing as I expalined |

Carrier Infinity Control thermostat problem
According to the manual for the Carrier Infinity Control unit the
"deadband heat/cool" setting only controls the minimum change of temp when the unit changes from heat to cooling. There is no other deadband setting that I could find. I don't know if you have time to take a look but here is the installation guide: http://www.xpedio.carrier.com/idc/gr.../uid01-1si.pdf We have noticed some improvement by setting the fan speed to low, but the actual room temp stills varies by two or three degrees without the change being recognized by the thermostat. Very frustrating. Thanks for trying to help. I really appreciate it. Jane |

Carrier Infinity Control thermostat problem
Well, looks like we solved the problem. I put a thermometer on top of
the thermostat. I kept track of when the temps changed and noticed it happened AFTER the furnace came on and shut off. That made me realize that the cold and warm air was getting to the thermostat from somplace other that the area around it. I looked around and found two heat registers that were closed in the dining room, which meant that area was colder than the living room. We almost never use the dining room but it's closer to the thermostat than the living room is. It was screwing up the heat. When I opened them up fully things improved dramatically. We are thinking about getting a remote room sensor so that the thermostat can react to the temp in the living room and not in the dining room. Do you know if the remote sensor can be easily deactivated so the furnace and/or air conditioner responds to the thermostat sensor if we want it to? Anyway, things are much better. Thanks all for your help. |

Thanks all for your help. Not sure if anyone brought it up or not, but: What is the wall like where the thermostat (interface) is mounted? If the installer left a good size hole (behind the thermostat) and you have a "draft" coming through it, that can really have an affect (or is that Effect?) on the operation. Just a thought... |

The new thermostat is in the same place as our old thermostat. I
didn't see them actual do the install but the old one was much small than the new one so I assume the hole is not big. I don't think they would have needed to make the hole any larger? I certainly don't see any space around it or feel any draft. Also it's an inside wall. Good thought though. |

Inside walls will get drafts too, but enough of that....;-] You know how they sell "gaskets" to put behind faceplates for switches and outlets in your house? That's kind of the same idea. Even a "figer-size" hole can let enough of a draft in to mess with the thermostat. The only thing is, if it didn't affect the old one, I don't see how it could now. |

Carrier Infinity Control thermostat problem
Did he run new wires, I bet he did with a fancy Ifinity and old wires
might have had hole sealed with caulk, you wont feel anything. Remove it and the plate and caulk the hole. Be sure mains furnace power is off and thermostat set to off first. Id say installer just missed this, but since you say he has many issues with other customers hes a hack. probably new in the trade. But im no pro either, just guessing. |

It's very frustrating considering the little sucker cost about $400. Thanks Jane Those thermostats have what's called an adjustable offset which means the temperature difference at which it turns on the HVAC system. It can actually be programed for a one degree difference even though most I've seen were set to 3 degrees. The offset keeps the system from turning on and off too many times per hour. You may also see it referred to as hysteresis. It can also be adjusted to come on at exactly your setpoint and cut off at a temperature 3 to 4 degrees higher than what you set it for. Electronic thermostats can be programmed to operate in many different situations but it takes someone who understands what is needed. 8-) [8~{} Uncle HVAC Monster |
