I was recently shopping at Home Depot B&M and saw this network thermostat - Filtrete 3M-50 for around $100

The price is significantly less than similar units out there - www.bayweb.com,, www.ecobee.com , www.proliphix.com.


Has anyone here purchased one of the Filtrete network thermostats ?

-Thanks

is the iphone app extra? is there an android app for it?

I did a little more digging... The thermostat is made by www.radiothermostat.com . The iphone app is free and they are working on an android app - see- http://forums.radiothermostat.com/


edit-

They also have released an Android application - (see - www.forums.radiothermostat.com )

This is oh so much better than the old BSR X-10 stuff.

looks pretty cool but I'm not sure how much it would help me. I need something will display the cost of current usage so my wife will realize heating isnt free and will use another blanket instead...

My CPS San Antonio bill this month offers one similar to this for free if you sign up for the peak shaving service. They use it to turn your AC off for 15 minute intervals 2-3 times a day max during the 4 peak months of June-Sept. You also get a $30 credit on your October bill for participating.

nsdp, more than likely they are using something that does not allow your A/C compressor to turn on during peak periods. Does not have anything to do with your thermostat. I am signed up for this. Your A/C continues to run, but it will get "warm" during these peak times due to the compressor being automatically cycled by the power company's device mounted to the side of your house.

Yes things have come a long way even since I purchased a Proliphix unit a few years ago. This IP / network / internet controlled thermostat seems like great deal if it is reliable .

However, depending on your need , you might want to pay for more for one of the other units that offer more features (eg- remote sensing, motion detection , appearance ,etc)

My earlier generation Proliphix internet thermostat unit ( cost about $400 at the time )is in an out of town vacation rental property. We regulate the HVAC during the vacant periods . There were some problems at first but I got them worked out. It has paid for itself about 5X in energy savings in the 3 year period. Proliphix has been at this for a while and has very good support. There is a Proliphix discussion group at Yahoo groups - http://tech.groups.yahoo.com/group/proliphixgroups/.

LOL! Me too . This is an ongoing "battle" at my house . At least one of these network thermostats model (Bayweb ?) offers a running cost calculation .

Here are some good blogs write-ups from a user with an Ecobee system. These things aren't perfect -

BTW- Some of these devices require you the use their server hosting (basic service free) and some don't ( Proliphix can work without using their server ).

So what you're saying is that they "proliphix"ed the thermostats and made them reliable.

So has anyone actually used one of these? I have a newer Honeywell 5-2 programmable.. Works fine. Don't know if I justify spending $100 on a techy gadget when mine works fine.

THIS X100

I purchased one of the Filtrete 3M-50 thermostats today and will install it in my house this weekend.

1. These are internet controlled / enabled thermostats. However, I cannot determine whether a user is required to use the company server to operate the Filtrete 3M50 ( ie- can you independently control (direct connectivity ) operation via private LAN or fixed IP / dyndns option - same question with the Bayweb and Ecobee ?).

2. Reliable - I don't know.
From their website- " Radio Thermostat Company of America makes the world’s most innovative home energy management solutions. For the past 30 years, we’ve sold millions of our thermostats and related products through leading retailers, as well as our extensive HVAC and dealer network and utility partners."

1. "So what you're saying is that they "proliphix"ed the thermostats"
2- "and made them reliable"


I agree . It depends on your needs . My current thermostat is an old single lever White Rogers (WR) bi-metal coil and mercury switch thermostat . I will keep it for backup.

What you need is a Honeywell VP 8000:
Temperature display offset
Heat / Cool range stops

I have installed the Filtrete 3M50 thermostat . I had to run another wire to the furnace for the "c" connection but there were no other issues. I hope that they will tweak /upgrade the firmware (and web controls) to offer some simple options that would make buying one of these more worthwhile .

More comments later.....

update -

I have experienced connection issues (both WIFI and cloud ) which have required resetting and re-provisioning the thermostat . Both of these tasks have to be performed at the location of the thermostat. The CS suggestions of moving from DCHP to static IP did not improve the reliability of connection. Maybe future firmware upgrades will fix the connection issues but they need to hurry up. In addition to resolving the connection issues, they should consider adding more features that would be benificial to the user of a remote controlled thermostat eg,-direct web interface (use of their clould server not required for local use), user set email alerts , passcode lock(for programming and display options), better backlight control.

There is a nice third party program which fills in some of the gaps . It is inexpensive but the features it offers should be included with the device (firmware/software). -

The Filtrete 3M50 / Radiothermostat CT50 is a new product that is evolving and I anticipate improvement over time . Depending on your needs (reliabilty and features), it may be better to pay the higher purchase for one of the more established models (Bayweb, Ecobee, Proliphix) for a situation like a vacation home at a distant location .

Thank you for the update. /sigh too good to be true eh?

or "not ready for prime time"

X10 is the way to go,that is if you still have a telephone.I rehashed one of their controls to turn my auto change-over thermostat off and on in a beach house,works perfect,works so well installed system in 11 of my neighbors houses,all are extremely happy.

It's funny, this thermostat is in my Home Depot ad. I don't think they upgraded the software did they?

I've had the 3M50 thermostat installed for 4 months now. I have not had any connection issues, or any trouble at all. I've got a an Android Phone, and my wife has an iPhone. We battle a little bit over the temperature - but other than that, the thermostat is working flawlessly.

I can confidently say that installing this thermostat has easily paid for itself already. I can think of at least a half dozen times where we left the house for the day and I used the phone to make sure the heat didn't turn on. When it's really cold here, it costs about $10/day to heat the house.

Be sure you have a C wire. This is A SECOND wire that goes directly back to the transformer. Older and cheaper HVAC systems usually do not have it. The R wire is the OTHER wire that goes back to the transformer and is always present.

Otherwise the thermostat will try to pull power from the heat, fan, or cool wires. So your system will malfunction or the thermostat wont work.

Systems with added-on AC may have two transformers which is going to create additional problems. Look for two R wires called Rc and Rh.

Its no freakin wonder that there are stacks of thermostats behind every Home Depot return desk. This product won't really take off until 3M offers a coupon or partial rebate for installation.

So maybe there will be quite a few of these marked down on the table.
