Suggest a Stat, Please

[Dad]

I am looking for a good replacement for what we have been using. The White Rogers 1F95-371 is perfect for our operation and our customers. Here is the link for those not familiar with this stat. Click Here for Stat Link (http://www.white-rogers.com/pdfs/04_Cat_pages/04_Cat_pg_008_009.pdf)

I need something that is digital, 7 day set back, power robbing without batteries, 2 stage cooling, 2 stage heat, remote sensor capabilities, compressor power failure lock out delay. Also it is real important to be able to lock the stat using a keyboard process and not a dip switch.

Cost efficiency is a plus….


I have been too busy to do research on this project but 2 out of 5 of these stats that we use go bad between the 1st day to the 3 week of installation… no excuse from White Rogers as of yet…

Can anyone suggest a better or equal stat for my commercial customers?

Thanks

[glennwith2ns]

has to be power robbing??????

[Dad]

batteries just don't get changed... must be hardwired w/ common wire and without batteries

sorry

Interesting! Here I am in the business and have been for over 30-years. Can afford any thermostat I want, get it wholesale and what do I choose?

I am sold on a simple Honeywell T87F and don't want anything else. My entire family understands it and it always works!

I have a stock of fancy digital programmable stats in my van and would not think of installing any one of them in my own home.

I actually use a 1F95-371 in my house. I keep it locked to keep everyone out of it!

This is one of the reasons why I need this kind of stat.

To keep unwanted employees out of it.

To automatically handle energy efficiency by use of set back.

Have you looked at the Totaline P374 series, 3 levels of security plus total keypad lockout, check them out here:

we have used them for years with only one defective unit that I can remember.

[hvacprodmgr]

Agreed.

Vision Pro can do that.
T7300 can do that as well

We junked the t7300's

Customers didn't like them.

I have my eye on the Vision Pro. I will give the p374 a look later this afternoon. Thanks.

Vision pro 8000 without a doubt.
In the chain I work for, as the t7300's need replaced I have been using the vision pros.
The managers like them because they are easy to make changes to, and they are nice looking.
They are now the spec in all new units.

[Dad]

So far I am leaning to the Vision Pro but i really like the Total line P374 too.

I want to purchase my summer/fall stock this next week.

Any more advice is very appreciated. Personal opinions are the best.

Dear Lusker,

We have used both the Totaline P374 and the Vision Pro 8000 and have found both to be excellent thermostats, but our higher than expected failure rate of the Totaline P374 coupled with our Client’s overall preference for the Vision Pro 8000 has increased our installation of the Vision Pro 8000 overall.

Although we do nothing but commercial, industrial, and institutional HVAC systems, we do on occasion replace thermostats in certain supervisors, and owner’s homes and give them a chose of several thermostats, the overall favorite has been the Vision Pro 8000 when a digital thermostat is selected (approximately 85% of the time).

That’s our take in Los Angeles.

Respectfully Submitted,
John J. Dalton

PS: Use to use the T7300 exclusively, but the Clients found them extremely complicated and user unfriendly, haven’t installed one in over four years now.

[john dalton]

Dear Lusker,

My above post was a combination of preferences from my Clients, my service technicians in the field, and myself.

Just a suggestion, if you have at least two separate HVAC systems at work, install one of both for a week or two, and then place the order based on all the information at this thread, and your own personal experiences.

Better yet, if you don’t have two HVAC systems at your office, then place one of each of these thermostats at your best Client’s facility, tell him you are conducting a test, and see what he says after a couple of weeks, after all, after pre-qualifying both these thermostats…………it’s not what we like, but its what the Clients likes that counts doesn’t it?

Just a though friend………

Mr. Dalton, your participation and opinion is appreciated.

Dear Lusker

As yours are my friend.

These stats are junk I installed about 20 of these on a new rooftop Install about two years later I have changed about 8 of them already. The reason I changed them there was no heat or cool operation just supply fan was running! I would not recommend this stat to anyone.

[Dad]

well guys.... I think I have found one... take a good look at this one

9715i for two stage
9701i for single stage
or the 9800 line for humidity sensing

I ripped a few of those off the wall and put in the vision pro sorry to tell you

Doubtful


Look again.. this is a new product line.


I have looked at the Vision Pro… I don’t like it for my commercial needs. It is also over priced for what it does.

[Diceman]

I vote the vision pro as well.
Carriers Debonair series is very good too.

same thermostats as the lennox signiture series. have sold them with no complaints. have had one in my house for almost 2 years. really like the menu driven set-up

[superfittertech]

the only problem with the invensys stats is the keypad lockout. there is 2 levels of lockout & you make up your own lockout code, but if you forget the code you have to reset the stat & start over on the programming. 2nd when you unlock the stat to make changes make sure no one sees you enter the lock code as they can then unlock it & change the code.
by the way honeywell now has a visionpro commercial stat

Just like me


I bet you walk in front of the mirror and admire your Willie before your morning shower too..

:D

[ac/dc]

Lusker, I am also in need of stats with all the features
you mentioned. What is the price of the 9720i ?
I have to replace 55 stats and I quoted the job using
the cheaper visionpro8000 but soon learned they require
batteries for operation(not just mem. backup) The "commercial" visionpro is $80 more with no batteries
I was leaning toward Danfoss which Ive used before
and liked but the security is a dip sw. But they are in the
price range I need.
I also have replaced alot of failed Totaline and Debonair

I am sorry. Forum Rules (http://hvac-talk.com/vbb/showthread.php?threadid=1241)

No pricing on the site unless you are a professional member in the professional areas and done only for marketing info.

Any good power stealing stat will not be cheat. the 9700 model is more expensive than the 1F95 series I was using by about $20.00 a stat.

The more I look at Vision Pro the more I don't like it. It may be the finest stat in the world but it is like this...

If spinich is the most healty food on the planet and every one else eats it, loves it, I will still pass.

[Freezeking2000]

What stat is offered that has the provision to close Y to the dehumidification terminal on a v/s ICP fan coil to slow the blower to 80%.

I currently have an ambient t-stat that slows blower to 80% below 80 degrees.

No..no..no... Justin, How many times do I have to tell you... that thing you admire most about yourself is called a Willie, not a weiner. Besides... there is no such word as a "weiner" (unless your hungry)... what are we going to do with you. Take you to the beaches of MD or something?

Freeeeeeezeeeee

I wish I could help you but I am straight commercial applications only. I do know the 9800 Robertshaw has dehumidification.... see the link above.

[ac/dc]

Yes I forgot about the price rule,sorry
I actually dont need "power stealing" stats. I have enough
conductors for a common. I rarley see power stealing stats
in commercial systems.
I'll check out the 9720i at my distributer, It may fit the
bill provided its not power stealing.
The commercial visionpro is not a power stealing stat.

[Dad]

ac/dc

then it will fit the bill as we have to run a common all the time whem converting.

the 9700 is about the same price as the VP

the 9800 is just a bit more

the 1F95 series can be a bit less but we have 1 in 4 fail.

this is why I am looking for a new stat.

In the past three weeks we have installed 3 cases of 2 stage and 1+ cases of single stage 9700's. All worked just fine. We went through the setting like a hot knife through warm butter. We locked them using the last 4 digits of our company's phone number. We even programed our company service name and number to show for service.

Sorry to all you out there that like the VP stat. I haven't said anything negative about it but to me it is like eating spinach.

shut up Justin. :)

OOHHHH you can do that hmmm I think you just sold me on those stats.


But its still not as pretty LOL

Do you mean to tell me that you have been giving me grief without doing research on the 9700 series? Hummmmm

Pretty is like your Willie, it is not functionial so your wife tells me :D:D
