Honeywell Thermostat Reading Wrong Temperature From Indoor Sensor
Honeywell is ane of the biggest names in home heating. Whether it'due south a basic analog thermostat institute in an older house or a state-of-the-art smart dwelling interface that manages heating, cooling and more, countless Americans use Honeywell thermostats.
The company has a reputation for making solid and dependable equipment. As with whatsoever technology, nonetheless, things sometimes get incorrect. While looking in the transmission is often the best solution for troubleshooting a thermostat, you're not alone by any means if y'all haven't been able to go on track of it over the years. Fortunately, nigh problems with Honeywell thermostats are fairly straightforward to solve. With the solutions beneath, y'all should be able to identify and solve the near common issues with your device.
Checking Temperature Accurateness
Before y'all have apart your Honeywell thermostat, it's a practiced idea to confirm it'southward actually misreading the temperature in the room. If your room thermometer and Honeywell thermostat match, so the problem 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 example, you lot tin choose between fixing the thermostat or purchasing a replacement unit.
In that location's ane easy fashion to exercise that: a room thermometer. If you doubtable that your thermostat is inaccurate, you should confirm that it's really misreading the temperature before doing annihilation else. To do this, take a room thermometer (not the kind you lot use to measure out your ain temperature) and let it take a reading. If your room thermometer and Honeywell thermostat friction match, then your trouble is probable to be with your furnace or air-conditioning rather than the thermostat itself. If the readings don't match, all the same, and so the thermostat's sensor could be malfunctioning.
If that'south the example, y'all'll need to either buy a new thermostat or recalibrate your old one. Unfortunately, the fashion to calibrate a thermometer tin vary greatly between models, then you'll need to identify what kind of thermostat you lot have before proceeding. Too, go on in heed that Honeywell thermostats are designed to account for radiant also as ambient air temperature. A small deviation probably isn't anything to worry near.
Analog thermostats are much simpler than their digital counterparts, and troubleshooting 1 is simpler yet. In most cases, issues are the result of the thermostat not beingness properly aligned. If the thermostat isn't level with the wall, the mercury switch could tilt and have problems reading the temperature in the room. If this happens, use a torpedo level to correct the alignment. The thermostat should likewise exist at least 5 feet from the floor and in a location with no obstructions that could interfere with air menses.
Grit can also crusade Honeywell thermostat problems. To bank check and clean out the dust on the inside, remove the thermostat cover. With a soft brush or cloth, clear away the dust gently, taking intendance not to harm the electronics.
There could also be an consequence with the wiring of the thermostat. If you feel confident (and ideally have your manual handy), yous can try to see if any of the wiring is out of society — colors should lucifer. Be aware, however, that you'll need to plow off power to the thermostat first earlier attempting this, and you could damage the thermostat if yous don't know what you're doing.
Blank Screens and Missing Readings
Is your digital thermostat non showing any data at all? If that'due south the case and you (or someone else) recently took a await at your heating system, the problem could be the result of not closing the furnace door properly. The furnace door switch won't permit the HVAC system to plow on, which in plough prevents the thermostat from working. Shut the door properly, and your thermostat will probable return to normal.
If the screen on the thermostat is completely blank, the circuit breakers for your HVAC or furnace could exist tripped. Check your circuit breakers and then flip them on and off. If that doesn't piece of work, a fuse may need replacing. This can be a whole project of its own, so you may want to hire a professional person to do information technology for you. However, it could also be a battery upshot, which is potentially much easier to solve. Speaking of which…
What a Blinking Orangish Lite Means
If you meet an orangish flashing low-cal on the thermostat, it probably doesn't hateful that your thermostat has stopped working still, but it volition if you don't practise anything about it. This light usually indicates a depression bombardment, and it may fifty-fifty show the words "replace bombardment" or "lo batt." While not all Honeywell thermostats apply batteries, if yours does and that lite comes on, you may have a limited amount of time before your thermostat shuts off (some other crusade of a blank screen, incidentally), although some thermostats only rely on bombardment ability equally a backup when they aren't receiving it from the heating organisation itself.
To modify the bombardment, simply identify the battery example (in that location'due south usually a seam) and open it. Many models have AA or AAA batteries, although some models may use others. Once y'all've replaced the sometime batteries, most of your settings should remain intact, although you may lose the date and time.If your battery draws ability wholly from your heating system or the local power grid, in that location will be no batteries.
