How To Get Honeywell Thermostat Back Online
Honeywell is ane of the biggest names in home heating. Whether information technology'south a basic analog thermostat found in an older house or a country-of-the-fine art smart domicile interface that manages heating, cooling and more than, endless Americans use Honeywell thermostats.
The company has a reputation for making solid and dependable equipment. Every bit with any applied science, yet, things sometimes go wrong. While looking in the transmission is often the all-time solution for troubleshooting a thermostat, you're non alone by any means if you oasis't been able to keep track of it over the years. Fortunately, almost problems with Honeywell thermostats are fairly straightforward to solve. With the solutions below, you should exist able to identify and solve the most common issues with your device.
Checking Temperature Accuracy
Earlier you take autonomously your Honeywell thermostat, it'south a adept idea to ostend information technology'south really misreading the temperature in the room. If your room thermometer and Honeywell thermostat match, and so the trouble is either with the Ac or with your furnace. If the readings don't match, then the thermostat sensor could be malfunctioning. If this is the instance, yous tin can choose betwixt fixing the thermostat or purchasing a replacement unit of measurement.
In that location's one easy way to do that: a room thermometer. If you suspect that your thermostat is inaccurate, you should confirm that it'due south really misreading the temperature before doing anything else. To do this, accept a room thermometer (not the kind yous utilize to measure your ain temperature) and allow it have a reading. If your room thermometer and Honeywell thermostat match, then your trouble is likely to be with your furnace or air workout rather than the thermostat itself. If the readings don't match, still, then the thermostat's sensor could be malfunctioning.
If that'south the case, you'll need to either buy a new thermostat or recalibrate your old 1. Unfortunately, the way to calibrate a thermometer tin can vary greatly between models, and then you'll demand to place what kind of thermostat you have before proceeding. Also, continue in mind that Honeywell thermostats are designed to account for radiant as well as ambient air temperature. A small difference probably isn't anything to worry about.
Analog thermostats are much simpler than their digital counterparts, and troubleshooting one is simpler notwithstanding. In most cases, problems are the outcome of the thermostat not being properly aligned. If the thermostat isn't level with the wall, the mercury switch could tilt and have bug reading the temperature in the room. If this happens, utilise a torpedo level to correct the alignment. The thermostat should too be at to the lowest degree five feet from the floor and in a location with no obstructions that could interfere with air flow.
Dust can too crusade Honeywell thermostat problems. To bank check and clean out the dust on the inside, remove the thermostat embrace. With a soft brush or cloth, clear abroad the dust gently, taking care not to damage the electronics.
There could also be an issue with the wiring of the thermostat. If y'all experience confident (and ideally have your transmission handy), you tin can attempt to see if any of the wiring is out of society — colors should friction match. Be enlightened, yet, that y'all'll demand to turn off ability to the thermostat start before attempting this, and y'all could impairment the thermostat if you don't know what you lot're doing.
Blank Screens and Missing Readings
Is your digital thermostat not showing any information at all? If that'due south the example and you (or someone else) recently took a await at your heating system, the problem could exist the result of not closing the furnace door properly. The furnace door switch won't permit the HVAC system to turn on, which in turn prevents the thermostat from working. Shut the door properly, and your thermostat will likely return to normal.
If the screen on the thermostat is completely blank, the circuit breakers for your HVAC or furnace could be tripped. Bank check your excursion breakers and then flip them on and off. If that doesn't piece of work, a fuse may need replacing. This tin can be a whole project of its own, so y'all may desire to rent a professional to do it for you. Nonetheless, it could also exist a battery consequence, which is potentially much easier to solve. Speaking of which…
What a Blinking Orange Low-cal Means
If you lot see an orange flashing light on the thermostat, it probably doesn't mean that your thermostat has stopped working yet, but it will if yous don't practice anything about information technology. This low-cal usually indicates a low battery, and information technology may fifty-fifty bear witness the words "supercede bombardment" or "lo batt." While not all Honeywell thermostats use batteries, if yours does and that light comes on, you lot may have a limited amount of time before your thermostat shuts off (another crusade of a blank screen, incidentally), although some thermostats only rely on battery power as a backup when they aren't receiving information technology from the heating system itself.
To change the battery, only identify the bombardment case (there's usually a seam) and open it. Many models take AA or AAA batteries, although some models may use others. Once yous've replaced the old batteries, most of your settings should remain intact, although y'all may lose the date and time.If your battery draws power wholly from your heating organisation or the local power grid, there will be no batteries.
