The display lets us know what the temperature is in the house. The display tells us what the desired settings are including letting us know the set point setting the temperature. Some displays give us the time and the newer modern displays show us family photos like a screensaver on our computer. But what happens when the display is not there or there is a blank thermostat display or no display on the thermostat? Is it a bad thermostat or something else that caused the display to disappear? Blank Display on Thermostat Problem — Types of Thermostats First, we need to distinguish between the different types of thermostats available on the market. There are thermostats that are battery powered only and need to have fresh batteries replaced from time to time. It is a possibility that your thermostat is this type of thermostat. You will notice the display starting to fade a little when the batteries are getting low. Furthermore, some of the battery powered thermostats have a battery indicator on the display and some do not.
Honeywell RTH6580WF 7-Day Programmable Thermostat Review
Is there another way to check and see if the wire is connected somewhere else before connecting to the furnace? It would be very unusual if the cable between thermostat and furnace connected to anything unrelated to HVAC components furnace, air handler, AC. Based on the number of cables visible in your picture of the furnace terminal block it appears that this is the location where all the connections are made and that is very typical.
For additional piece of mind, you can use a multimeter and make the following measurements after disconnecting the black wire on both the furnace and thermostat end: Don’t worry if there is a low reading as a small amount of voltage may be induced into the open wire from nearby electrical circuits. The primary purpose is to determine that it is safe to measure resistance which should not be done if there is a voltage present.
Honeywell thermostat Once installed it works great. “The instructions are difficult to follow” and the unit to install the wires comes out to be tightened then snapped back Rating: % positive.
Now the bad part To sum it up if you are going to place this well away from any rooms that you spend time in or you have a well sound proofed house then this will work , if not You will never get to sleep with the constant clicking on and off all night. I bought this thermostat because I trusted the brand name and wanted something sleek and low profile. It is good but it makes, what I consider to be an awfully loud noise when it clicks on and off. To give you an idea of how loud it is, we can hear it click from any room in our house, even with the internal doors closed.
If you’re a light sleeper – it will wake you up if it comes on at night. I did email Honeywell support about this thinking it could just be a faulty unit, however after some further research it turns out that this is how it was designed – I never heard back from Honeywell support either. One other point to consider, this is branded as an Eco device which to a certain extent it is. The issue i have is that this is a manual setting, not an automatic one. So unless you want to be ‘interactive’ with this unit I’d suggest not paying the premium.
Furthermore it does require batteries, if the batteries run out whilst you’re away the unit will not work; although this is true for any of the LCD type thermostats. I’m going to buy a plain ‘ole simple unit that does not make a loud click and requires no batteries. They are much cheaper and more reliable. I think it’s only fair not to buy a Honeywell unit either – I like to know that if I encounter a problem; there is technical support available.

The old WeatherTron was also really ugly. Having two heat sources, the electric heat pump and the furnace, seemed to complicate the setup and install of the new Thermostat. Since it took a lot research and verifying to find where all the wires from the old unit hooked into the new one, I thought it may be helpful to post the wire translation that worked for me.
With R, day thermostat is out of control at night, but its contacts must be closed to permit night thermostat to operate. 4. In D·C districts where timers can’t be used, T42A thermostat and L40SA Stoker switch can be used, up to,\i hp; T44A, RISA D-C relay and L40SA from >i hp to Y2 hp.

Honeywell Thermostat Wiring Instructions
Wax thermostatic element Car engine thermostat Perhaps the most common example of purely mechanical thermostat technology in use today is the internal combustion engine cooling system thermostat, used to maintain the engine near its optimum operating temperature by regulating the flow of coolant to an air-cooled radiator. This type of thermostat operates using a sealed chamber containing a wax pellet that melts and expands at a set temperature. The expansion of the chamber operates a rod which opens a valve when the operating temperature is exceeded.
The Nest is a decent thermostat but the best thing for you to do is to do a comparison for benefits from one thermostat over the other. Compare features and options of the Nest to the Honeywell thermostat.
The first-gen Echo was a wine-bottle-sized speaker, with far-field always-listening microphones that allowed you to talk to it from across the room. It can answer questions , play music , control smarthome devices , and act as an intercom of sorts with other Echos. However, to make up for the lack of speaker, it contains a line out port that lets you hook it up to your stereo or other big, high-quality speaker. Keep in mind, though, that all of the newer Echos have a line out port now.
The original Echo Dot contained a volume wheel along the top, just like the original Echo. However, that was shortly discontinued, and replaced with a cheaper version that contained volume buttons instead. You can also watch videos on it, see a feed from your security cameras, video chat with other Echo owners, and do a few other things that require a screen. The Echo, Generation Two:

Install Your Own Line Voltage Baseboard Heater Thermostat. Updated on September 28, A thermostat with a display and lighting of that display should be chosen that is usable by the owner. and 4 wires coming out of the thermostat (labeled L1,L2,T1,T2). So I think I need to hook up L to L1 and T to T1, and then run a pigtale from L to.
Two heat settings and fan only. Exceeds industry safety standards: The Honeywell HZ , Honeywell Surround Fan Forced Heater features an incredibly unique degree radius design that allows for superior all around heating. This feature can easily be adjusted and redirected in the direction of your personal choosing. A fully imagined adjustable thermostat has also been included and was designed to be especially accessible and easy to read.
The ability to navigate between two heat settings and the presence of a fan add even more flexibility to a heater that’s inherently versatile. Surpassing industry standards, Honeywell has gone the additional mile in incorporating numerous nods to safety into their series of portable heaters.
Honeywell T6 Pro Installation Instructions Manual
I really appreciate your info and it gives me a lot of ideas. One problem with any manual thermostat solution that’s not automatic is this: I could trivially put another switch breaking the thermostat line on the wall near the door, but it’s not exactly what I need. The scenario that I’m trying to avoid is that my wife has a garage control on her key-chain and has accidentally hit it a couple of times in her pocket or purse.
The alarm contacts are already installed, I just need something to hook it up do. I also have a problem with the batteries for a digital thermostat because the temperature swings will destroy the batteries I don’t run it all the time , possibly damaging or destroying the stat or the wall behind it.
Ok, so I have a Ct Thermostat hooked up to control my Family room fireplace. Currently it is running entirely on batteries as there are only 2 wires coming from the fireplace to the thermostat.
Perhaps the easiest way to reduce residential heating and cooling energy usage is to turn back the thermostat when people are away from home or sleeping. By “turn back” I mean two possible things: Lower the temperature during heating season; Raise the temperature during air conditioning season. Why Does This Save Energy? One of the fundamental laws of the science of Heat Transfer is that the rate of heat transfer between an object and its surroundings is proportional to the difference in temperature between the object and its surrounding environment.
If there is a big difference in temperatures, your house will lose more heat per hour than if the temperature difference were small. A couple of years ago I wrote a little article about the science of heat transfer , and it explains this in more detail. The basic Honeywell thermostat. This device controls both heating and air conditioning. It also has a fan control switch, which you can see in the photo, that lets you run the fan all the time. These Honeywell thermostats have a plastic ring that just pulls straight off.
There are some exposed electrical connections here, but this is only 24 volts AC. In this house the furnace is in the crawl space.
Honeywell Lyric T5 Wi-Fi Thermostat
You will most likely be working on circuits that carry volts; a shock from this voltage can be deadly and even a simple shorted wire near fingers will produce a very nasty burn. Remove the old unit. Most are connected via wire nuts to wires coming from inside the new thermostat, but some can have screw terminals to attach wires to.
If possible, make note which wires are “line” and which are “load”. A single pole thermostat will have 2 wires going to it while a double pole thermostat will have four wires.
The basic Honeywell thermostat. This device controls both heating and air conditioning. It also has a fan control switch, which you can see in the photo, that lets you run the fan all the time. I didn’t need to curve the wire into a hook, just slide the wire under a metal piece and tighten the screw. Then I turned on the power to the.

When a room cooled below a predetermined temperature, a thermostat closed the circuit and energized an armature.
What is the C wire that is needed for a Wifi “smart” thermostat?
How to replace an old Honeywell thermostat Elizabeth Knoll Updated February 21, You are most likely familiar with the old Honeywell thermostat, especially if you are looking to replace one. The most commonly known old Honeywell thermostat is the manual round style thermostat. If you want to replace one, you should put in a programmable digital thermostat. These programmable thermostats allow you to have the thermostat automatically adjust the temperature up and down based on a program that is predetermined by you.
I know to hook the red wire to the RC terminal on the new thermostat and the white wire to the W terminal. It has a red jumper wire from the RH to RC terminal and a yellow wire to a Y terminal.
Honeywell evohome is the original and best multi zone solution. If you are interested in controlling your heating system with Honeywell evohome and trying to understand what evohome items you need, please read the following information. What do you need to know about Honeywell evohome? Honeywell evohome is capable of controlling up to 12 heating zones and when used in a multi zone environment, all the other wireless evohome devices communicate directly to the ‘master’ evohome Controller using a secure 2-way point to point communication protocol called ‘Ramses II’.
The RF signal used by evohome is truly excellent and typical range in a domestic property is 30m from the evohome Controller to the relevant evohome components. However, there are no wireless range extenders available for evohome, so if you have a very large property or a property constructed with materials known to cause existing RF issues, then we suggest your home is tested for RF signal strength with one of our RF test kits prior to purchase Click Here To Hire Our RF Test Kit.
Honeywell evohome is capable of being used in many different ways and with different heating technologies. Honeywell evohome is typically used with wet heating systems, however if configured correctly and installed within its limits, it can also work in electric only heating environments such as infrared panels. Below are some examples of how Honeywell evohome can be used and what basic equipment you would need for the application.
The majority of Regular Boilers will be connected to an S-Plan 2 or more single port zone valves or Y-Plan mid-positioned or 3 port valve system to allow the heat produced from the boiler to do heating, hot water or a combination of both. All of the heating components required for the system Pump, Expansion Vessel, etc are usually fitted inside boiler. These are also capable of being controlled by Honeywell evohome, however caution must be taken as some existing boilers have manufacturers controls with integrated diverter valves inside the boiler instead of external controls such as S-Plan or Y-Plan and this may mean Honeywell evohome will not be fully compatible.
