Will this handle a "dual fuel" setup?

This question is from 7-Day Programmable Thermostat
Asked by
Read all my Q&A
February 10, 2014
I have traditional baseboard heat that is fueled by a furnace using oil. I also have a newly installed AC/HeatPump Mitsubishi system installed throughout the house.

Will this device be able to handle BOTH tasks? Ideally, I'd like to use the heat pumps in the winter down to 30 degrees outside - then have the oil heat take over when below 30 degrees (due to the heat pumps inefficiency).

If not, can anyone recommend something else?

Answer: 
Obviously, I'm not there to actually see your setup, but this thermostat should handle both types of systems. Be sure to follow the directions to the letter and label each wire as you remove the old thermostat. The main thing to remember when replacing the old thermostat is to cut the power to the heating/cooling unit BEFORE changing the thermostat.

One of the reviews had a picture showing the enclosure to be partial (not entirely covering the top or sides). Is this still true? or did the owner leave off additional pieces?

7-Day Programmable Thermostat is rated 3.7 out of 5 by 109.
Rated 5 out of 5 by from Lots of Connections It has lots of connections so it should work for most applications. Installation took 15minutes in the dark using a flash light. Programmable for 4 different temperatures 7 different days each week. Trouble free for almost 1yr and counting.
Date published: 2013-03-12
Rated 5 out of 5 by from Excellent product Factors for 5 star rating: -Easy to follow, clear instructions -Comes with very nice labels that I used before removing the wires. This is something that I did not think about, but 3M thought of it for me :) -For the price and features this unit has, it cannot be beat. I checked bidding sites, local listings, and competitors. You can do your research so that you will feel as good as I do after purchasing and installing this unit!!! -Works with various different setups, including Heat Pump w/Aux and Emer Heat -The unit looks better than what is shown in the picture on this website (3/15/11) -Even though this is 7-day programmable, my use is really 5-1-1. I thought it was going to be a pain entering in all the schedules but there is a "COPY" button on the unit that will copy the settings onto the day following your selection -This should really say it's 7+1 programmable... Has a vacation mode setting that also has the option for morn, day, eve & night -Energy save button is a awesome! Whenever I'm going out for a few hours, I just hit the button and it automatically reduces the scheduled temperature by 5F -It has a quick button to switch between C and F right on the front. No need to open up panels and mess with any jumpers -LCD has a cool feel to it -If you are not a techie person and don't want all the details, you can switch the screen to "simple" mode that will just display the temperature -The unit I got takes 3 AA batteries. I'm thankful that it did not use CR2025 or one of those fancy digital camera batteries. This way I can easily use my rechargeable batteries -To the person below whose unit died after a year... FYI, it has a 5-year warranty from home depot. Don't need to buy a new one. This is why I purchased this unit because others, ie honeywell only has 1 yr warranty. Tip: If you have B, O and C wires, O -> O, B -> C, tape off C and don't use it for this model (This is in the instructions but I thought I'd post it here just in case)

Rated 2 out of 5 by from Looks cool and cheap, but bad side finish. First of all, the picture shown at home depot website is outdated. New model does not have cover over buttons and buttons look very different. Check picture from their website. I want to give link to it, but home depot rejected my review for wiring URL. At first impression this thermostat looked cool with blue back-light. However, having so many buttons exposed make it look very complicated. Also, sides do not have cover and you can see a deep voids on each side of thermostat. It looks very ugly from sides. On the top, you can actually see wires entering thermostat because there is nothing covering it.

Rated 3 out of 5 by from Not an easy install Has nice features for the price, and the warranty, however, it doesn't have enough room to route 4-5 wires to the terminal block. Very poor design compared to ones I've installed before Also, instead of programming 5 days then 2 days you have to program a day then copy it to other days a little more time involved. Also, the the alignment install holes are different seems like the companies would make them all the same so when you replace an old one

Rated 4 out of 5 by from Good value and works well. I purchased three 3M Filtrete 7 Day Programmable Digital Thermostats to replace the manual thermostats that operate different zones for radiant floor heating in my house, so I only needed to use them as a 2 wire heat only application. They are capable of much more. I took a chance on these thermostats, as I could find no reviews of the product anywhere. They were $10 less each than the highly rated LUX TX9000TS. I am very satisfied with the product and plan to buy more to replace my remaining thermostats. I rated them 4 stars instead of 5 stars only because of the housing and mounting hardware (more on that later), otherwise they are great. The installation instructions were clear and installing them was a snap. Programming the thermostats was also easy and again, the instructions were clear. I wanted 7 day programmable thermostats because of my irregular work schedule. It took very little time to program the thermostats. By the time I installed and programmed the third thermostat, I was a pro at it. I especially liked the copy function. I was skeptical that is would be easy to use, but it was. I had no trouble copying one day to the next when I wanted to use the same heating schedule. Of course we have cold winters in Wisconsin, and I am happy that my master bath will now only be heated for an hour in the morning and an hour in the evening instead of 24 hours a day, 7 days a week. I am also happy that the temperature in other parts of the house will be setback during non use periods. I recommend this thermostat. The only negatives I have, as previously mentioned are the housing and the mounting hardware. Although the housing is fine, it seems a little substandard. I had trouble fitting one of the covers onto one of the three thermostats, but eventually, I was able to attach it. Each thermostat comes with four screws and four drywall mounts. The drywall mounts are the smaller ones. The screws also are very thin and I bent one of them during the installation. I tried to replace it with a thicker screw that I had on hand, but the head of the replacement screw was too large to fit into the mounting bracket. I would not let these minor faults deter anyone from purchasing the 3M Filtrete 7 Day Programmable Digital Thermostat though. I think it is a great buy and a good product. One last thought: I think it would be nice if the required drill bits were included, one for the drywall mounts and one for the screws if mounted directly into wood.

Rated 5 out of 5 by from Good Value Don't let the one star reviews for this thermostat scare you from buying this unit. As you probably already know, most people can't read directions. This unit comes with a help line in case you need help. The directions are very straight forward and I had no trouble installing this unit. I replaced a Honeywell 5-1-1 programmable thermostat with this unit. I bought this because it was $10 cheaper than a comparable Honeywell unit. I had no trouble hooking up the wires, or covering up the hole where the wires come out of the wall. The battery compartment is in the front, under the display, which is extremely convenient IMO. There is no separate mounting base that snaps off the main unit, so it is a little difficult mounting the thermostat to the wall. Other than that, this thermostat was easy to install and functions flawlessly.

Rated 2 out of 5 by from Died after a year and a half Good thing Home Depot has a 5 year warranty on this product. Mine died after a year and a half - no display, no lights, nothing. Put on fresh batteries and verified the voltage at the main board. Still no go. Otherwise it worked well.
Date published: 2014-07-19
Rated 4 out of 5 by from Good thermostat if ... My old Honeywell needs replacing and immediately I went for another Honeywell thermostat. Tried 3 different 5+1+1 & 7 days programmable thermostat but none worked. Bought a 3M22 for its price (features are like Honeywell RTH64000D but without auto switch over cool/heat) and it worked. As opposed to those Honeywell models I tried, the 3M22 display screen works and the heat/cool and fan work too. The flaw about 3M22 is not the awkward dry cells placement, it's the fact that it does not fully cover the hole in the wall. The instruction booklet says it will, but that's only if you're going to look at it from the front and ignore the hole in side views. 3M should have designed a front load 2-battery tray for both sides, and the hole in the wall will be covered..The 3M22 is a good thermostat, but I'll have to return it.
