Honeywell TL8230A1003 Line Volt Thermostat 240/208 VAC 7 Day Programmble

Used this thermostat for 20 years with cove heaters for garage. Excellent thermostat and super easy installation. Looking forward to the next 10 years. Thank you Honeywell!

I have had several Honeywell digital thermostats but this was my first digital line voltage thermostat (240v). Install was fairly easy though I am not an electrician. This thermostat replaced an old dial type used on baseboard heaters. I could not get control of the heater using the old dial type since it had no display and even the slightly turn of that dial yeilded a huge change in output to the heater. This new line voltage/digital and programmable thermostat did exactly what I needed it to do and more. Very pleased with it. The display is large and backlit when the button is pushed showing nice backlighted display. Programming is a little quirkie but once you spend some time with it you can figure it out but instructions are a little lacking. Stay, Away and Vacation mode. Comes with programmed settings that can be easily change. I purchased 2 of these now on separate purchases I like them so much. The relay click is hardly noticeable which is nice. No real take aways really. It is nice looking. Very accurate to 1 degree of temp which you can see easily now. These will save me lots of money and I know will make my house much more comfortable. I would highly recommend if you need a programmable digital line voltage thermostat.

Works great highly recommend

Very easy to put together. The light on it is bright and makes the screen easy to read. The only negative is the batteries going out because when they do your thermostat just turns off until you realize there is a problem. I am going to try and see if I can find better batteries to see if that helps them to last longer than the ones I initially put in did.

I received my order of 5 Honeywell TL8230A1003 Electric Heat Thermostat Line Voltage Digital 7 day programmable thermostats one week after I placed the order. The units arrived well packaged, are solidly built and are much nicer and smaller than they appear onscreen. I had a licensed electrician install all 5 a week ago, replacing my 25-year-old units. The electrician had never seen this particular thermostat before, but because of the straightforward installation guide coupled with his experience, it only took about 20 minutes to install the first unit, and about 15 for each of the remaining 4. Within minutes I had them all programmed!The Honeywell TL8230A1003 Electric Heat Thermostat Line Voltage Digital 7 day programmable thermostats are incredibly easy to program, and have icons that correspond to different functions (i.e., comfort mode, night mode, away/vacation, manual, etc.). I consider myself to be very "tech-savvy" and don't like to read manuals if I don't have to. With this product, I was able to figure out how to use every function, with minimal time, and without having to study the instructions (which, by the way, is just a front-to-back insert). Further, because they are connected to the heating unit power supply, there are no batteries to change. The only down side to this is that in the event of a power outage, I believe all the programming will need to re-done. Still, it's a minor inconvenience.The most wonderful thing about these thermostats is the ability to program 4 different times for each day of the week. Though they come pre-programmed, re-programming is completely customizable. For example, for Monday and Tuesday, I can set the three downstairs units to come on at 5AM, go off just before I leave home, come on again an hour before I return and go off again an hour after I go to bed. I set the living room and dining room units to only come on in the evening. For Saturday, I program a totally different set of times, and on Sunday, yet another set of times. The thermostat also has an "On/Off" switch that allows me to turn them off if I don't want the timed setting(s) to come on, as well as a "manual" function that allows me to completely override the programmed setting and increase or decrease the desired temperature. The thermostat is also EXTREMELY QUIET when switching on and off in timed modes, and has a backlighting feature accessible by a long bar-type button on the face of the unit - perfect for checking temps in the dark. Each of the setting buttons is made of non-slip rubber so fingers won't accidentally slide off during programming. The buttons are small, though, and there is no backlighting for the buttons. The only caveat is to be careful not to press the "clear" button unless you actually WANT to clear a setting. This button is not in a separate area of the unit, and I inadvertently cleared one of the programmed times.All in all, I am very satisfied with this product. What a great feeling to wake up in the morning or come home in the evening to a warm home! And the cost savings as a result of being able to use heat only when and where I need it are sure to be another benefit. I'm so pleased with these new thermostats that I've recommended them to two of my neighbors/friends, and I expect that they will purchase new sets within the next couple of weeks!To summarize,Pros:Small and sleekEasy and quick to install by licensed technicianEasy-to-understand iconsNice "green-glow" backlightFully customizable programming - up to 4 time settings for each day of the weekProgramming buttons have non-slip surfacesOn/Off switchExtremely quietNo batteries to replace - ever!Cons:No battery backupProgramming buttons are small and not backlit"Clear" button is not in separate area of the unit

Living in an all electric house has it's pros and cons. Here in Colorado, my power bill over the winter months is sometimes 400+ dollars in one month. I had 5 of the original heater thermostats for my electric baseboard heat controlling 10 or so heaters in total. I've replaced one of the old ones so far, and will be ordering more.The hardest part of the installation was determining which of the existing wires in my wall box were load, vs. line. I highly recommend that you also purchase a load/line tester. Home depot has them for 8 bucks. Most of the ones on amazon do more than what you need, I purchased one that can support up to 220 volt circuits, but this was not necessary in my situation as each leg of the 220 volt circuit is tested separately.. you shouldn't go over 110 volts that way.. Anyway.. After shutting down the power to the circuit, I removed the old thermostat and wires which I made sure were free and clear of each other. Then you simply turn the power back on and test each individual wire, connecting your black lead to the ground wire, and then touching the red lead to each of the wires that used to be connected to the thermostat. Take your time here and make sure nobody in your house (kids, etc) are running around where they could potentially get fried... obvious safety measures should be taken of course. Now that the line and load wires had been identified, I shut the power off again and labeled them.The back of the Honeywell unit has a little diagram on it showing you where to connect the line and load wires, generally you will have 2 lines (one from each leg of your 220volt circuit) and 2 load wires which only become 'hot' when the thermostat turns on. The colors of these wires will depend on if your previous install was done to code, when it was done, and by who, so I never trust it until confirming they are what I think they are.This unit installed in the same 'single' width gang box my previous thermostat was in, and includes new 'screw on' wire nuts to make the connections. The entire install took about 35 minutes, most of that time was spent on safety. Having live wires sticking out of your wall (when you are testing to see which ones are the lines) can be a bit nerve wracking for non-electricians. Take your time.After turning the power back on and doing a quick 'smoke test' to make sure everything was good to go, I reprogrammed the unit for our specific schedule. Waking up to a warm house and never really having to touch this thermostat at all are good enough reasons to get one of these programmable units. The major bonus was cutting my power bill by over 100 bucks last month. Winter is winding down, but I will be replacing every thermostat in the house with these. They will pay for themselves the year you install them.
