3M Filtrete Thermostat. 7-Day Digital Programmable Thermostat 3m-22

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.

Eats batteries and cheap plastic tabs break

The unit eats batteries, despite being wired per instructions to a modern heat pump/air conditioner. Only 1.5 years old. Also, the plastic tabs that hold cover on are breaking off due to poor design for access--not room for all the wiring, is part of the problem.

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...

QA is a joke

What are the chances I get a defective product. The unit would turn the fan on but not the Heat nor A/C. Be careful with this product... It may cause you to spend more money on HVAC service call.

Nice unit so far, time will tell.

Took a little longer to replace than the suggested 15 minutes since the annotations on the old thermostat didn't translate to the Filtrete. A few minutes on the internet got me the installation instructions for the old Honeywell and I could get things cross-referenced. Programming was easy and perfect for my odd work schedule/days, the old 5-2 thermostat just wasn't what I needed. So far it works...

Took a little longer to replace than the suggested 15 minutes since the annotations on the old thermostat didn't translate to the Filtrete. A few minutes on the internet got me the installation instructions for the old Honeywell and I could get things cross-referenced. Programming was easy and perfect for my odd work schedule/days, the old 5-2 thermostat just wasn't what I needed. So far it works as advertised, time will tell how durable it is. Note/Comments on lambition's review & pictures: There should be a piece of thick white tape in the package to stick on top to cover the wires. I agree that it's not a great design or solution, but it is what it is. I think the gaps in the side are for optional add-on modules, like a WiFi receiver from the more expensive model. I'm guessing that's the only difference between them, WiFi receiver or not.
