The short answer
The Carrier Infinity Touch control in Northern Virginia homes does more than a regular thermostat, so most questions about it are about settings, not failures: how to hold a temperature, why the fan runs for a minute when you turn the system on, how to clear a reminder, and how to unlock the screen. Each answer here is from Carrier’s owner’s manual, along with what a real fault looks like.
Holding a temperature
Change the temperature on the main screen and you can hold it. HOLD UNTIL keeps it to a time you pick, in 15-minute steps, and then the schedule takes back over. To hold it for good, touch HOLD UNTIL and then HOLD. To go back to the schedule, touch HOLD UNTIL and pick PER SCHEDULE.
The $67 Heating Check
We check your furnace, heat pump or boiler before winter. Through December 31. See the offer
Home, Away, Sleep and Wake
The schedule runs on four activities, HOME, AWAY, SLEEP and WAKE, each with its own heating and cooling settings. AWAY has an extra Carrier calls Advanced Smart Setback: you set a range, and the control picks a temperature inside it to save energy while still getting the house back to your setting by the time you’re home. If the house sits somewhere between your Away limits, that’s this feature working.
Why the fan runs when you turn it on
When you switch from OFF to Heat, Cool, Auto or Fan Only, it’s normal for the blower to run for a minute or two. Carrier says the system is working out how much the filter has been used, and it can’t be turned off. If the fan runs all the time after that, check the fan setting before you call.
Humidity
With a humidifier, you can set the winter humidity anywhere from 5% to 45%. In summer, the control can over-cool the house a little to pull more water out of the air, up to 3 degrees cooler than your setting, and it asks you YES or NO before it does.
Clearing reminders
Reminders show up on the screen for the filter, the humidifier pad, the UV lamp and the ventilator pre-filter, if you have them. Once you’ve changed the part, answer YES to reset that reminder, then SAVE. Service reminders can be set anywhere from 3 to 18 months apart.
Screen locked?
Hold UNLOCK, in the bottom left corner, for 10 seconds.
Software updates
When the control is on Wi-Fi, a reminder shows up when an update is ready. Answer YES and it downloads, reboots and keeps your settings. Without Wi-Fi, an update can be loaded from a micro SD card, 1 to 32 GB, formatted FAT32.
One setting that sounds bigger than it is: Restore UE factory default resets only the utility event settings, the ones a power company program uses. It doesn’t wipe your schedule.
When it’s a real fault
A System Malfunction message, or an entry in the control’s service log, means the equipment is reporting a problem to the control. Carrier’s manual sends you to your dealer for those, and our Carrier Infinity System Malfunction guide covers what to check first. If the furnace itself has a code light, our list of Carrier furnace codes tells you what it means.
