Discount Honeywell RCT8100A 7-Day Programmable Thermostat

Customer Ratings:

I bought two of these thermostats (one for each floor of the house) at Costco a few months ago for around $35 each. They installed quite easily. The instructions are thorough, well illustrated, and easy to follow. The unit allows you to program temps for 7 days of the week in 4 different periods of the day (ex. mornings, leaving the house, returning home, and evenings). I have noticed a definite savings in my electric bill since installing these units. No more cooling an empty house or coming home to a warm house in the summer. It even has a reminder indicator so you can change your filter. The temperature controls (up and down buttons) are located next to the large backlit LCD display. However, to access the setting buttons, you have to remove the faceplate. My only complaint is that the faceplate is not hinged to the unit or slides to the side. No big deal though as these controls are seldom used. Another reviewer here rated this thermostat 1-star entirely based on the faceplate. That's ridiculous! Unless you have hands like the Hulk, the faceplate is easily removed.

I highly recommend this thermostat.

This is a great thermostat for saving money... seven day programable and easy to use... we share office space and it took everyone a few weeks to get comfortable with adjustments... it is simple and straight forward, all you have to do is read out of the book... i have recently ordered our second one for our hOMe... all the fuss over the cover-plate is just silly... yeah, it might not be like "easy" flip doors that you might be used to but all you have to do is slow down and exercise some patience and learn how the "New" one works... silly to knock a product because of some cosmetic issue you have... it is OK to mention design, but "How does the product WORK?" It is GREAT... like i said, it SAVES US MONEY!

Best Deals on Honeywell RCT8100A 7-Day Programmable Thermostat

The installation instructions for this model are uncharacteristically poor. Despite having installed similar units, I ended up puzzled and without air conditioning because of a mysterious unaccounted-for wire. The electrician who came out said ours was the second Honeywell RCT8100A that he'd rewired THAT DAY that they're popular because Home Depot and Costco carry them but the directions are "lousy."

The thing runs just fine now that the wiring is correct; the case and buttons are sturdy; the display is easy to read; the clock and programs are easy to set; the cost is moderate.

BUT users need to know something else, which I finally found online: With this model, if you turn the temperature up or down a bit (overriding the programming with a manual setting), it will NOT return to the programmed settings when the next time period starts. Other Honeywell models do, other brands do, and it seems clearly desirable that they should. Nevertheless, this model will retain your manual setting until you pry off the face plate and press "Mode" and make sure the little house icon is showing and not flashing in the lower lefthand corner.

So all in all, I'd suggest another Honeywell model. It's a good company. This model was just not their best effort.

Honest reviews on Honeywell RCT8100A 7-Day Programmable Thermostat

I thought I got a good deal from Costco at $36.99 for a name brand thermostat. After I opened it, I can not believe I need to remove the cover to turn ON/OFF the system. Not sure which genius designed it....and who was the supervisor to approve production? This should win the worst product design of the year. Returning back to Costco ASAP.

I am buying the 6350 for the same price on Amazon, yeah!!

This is the most awful thermostat avoid this unit. You will regret it, break it, then ultimately replace it despite the cash investment and sufficient feature set.

Before I begin, understand that my husband and I take care of our things. We maintain appliances, autos, shoes (etc) with great care, ensuring their usefulness long after their expected lifetimes. That said, we've had this thermostat a year and are today purchasing a replacement.

I just broke the front panel to this infuriating appliance. The design is flawed there is no natural release mechanism to get into the controls beyond the up and down arrows they are all behind the panel. To remove the panel, you pry it off with your hand. We've looked over it's design over and over, yet there is no means of safely removing the panel without prying it off with all 5 fingers. Worse yet, when it comes free, it resets and you are obliged to spend 10 minutes to reprogram the thing. Now we don't even bother we've given up.

It's absolutely awful. Spend your cash on any other unit even one that isn't programmable. This will save you more money than this terrible thermostat.
