Honeywell thermostat

[gusherb]

Pro1 IAQ?

I tried their T701 single stage non programmable. I must've gotten a dud because set to 70 it let the house get to 66 before turning the heat on, then would let it get up to 74 or so before shutting it off. That was the first thermostat I ever got rid of...
I still have a T755S sitting in my drawer that seemed ok though.
The casings seem sturdy but I'm skeptical about the electronics.

Upon testing a few years ago I found many issues with accuracy among various models.
The only two brands that really are acceptable are Emerson and Honeywell, and even then different Emerson models vary temperature readings by a few degrees. I honestly don't know how any variation is considered acceptable considering that they've made some models read inaccurately for years. [this post was last edited: 12/19/2017-14:39]

That's IT

Oh, how I dislike it!!!

Thank you, GusHerb.

Picked up the new Emerson 80 series thermostat and a Honeywell T4. The Honeywell is shockingly complex for a $40 thermostat, many features for what it is and many installation options. The Emerson has a surprisingly high contrast display, brighter backlight and built in level. They both have quieter relays than older models.

Gonna see how accurately they read temperature...

Digital has come a long way for sure...

 

[gusherb]

Preliminary results look good.

I have this....

Honeywell that has been in my house since the 40's. Its heat only (some of you may remember being introduced to Big Bertha). I love the look of it, I really don't think I would have another.

Emerson

 
We have four Emerson Sensi thermostats at work.  They work pretty nicely.  Support two-stage cool and heat.  The WiFi app allows access to auto heat/cool switching which the buttons on the 'stat itself doesn't.  The only way to program a schedule is via the app.  The app has a keylock function which makes the buttons on the base non-responsive as a security measure.  A new feature added recently is geofencing, which triggers heating or cooling setback/recovery when the homeowner is +/- 3 miles distance from homebase (although it's useless for a business situation).  I'm the only employee who has the app so nobody else has control of the systems.

Dislikes:  Neither the base unit nor the remote app has indication of 1st/2nd stage operation.  They updated the WiFi app recently to force arrangement of the programmed days into alphabetic order instead of as entered, which throws me off kilter because I want them in order of F-Sa-Su-M-Tu-Th which is logical for the business week.  It also now combines days that are the same.  I need them all to remain separate because a couple/few given days may be the same this week but different next week and it's an ass-pain to re-separate them when necessary.  The work-around is to program extra temp points (even if it doesn't involve a change) so all the days are different.  Would be nice if fan on or auto could be programmed on the schedules.

The T87 were good. My parents has one, but over time, it had too wide of a swing, so I repalced it with another one, some off brand digtial in the 80's, and did ok till mid 90's when new Trane was installed.

I have the Honeywell VisionPro IAQ, that controls my Trane XV90 two stage, humidifier, a/c, fresh air damper, and blower speed for dehumid. Been super pleased with that for the last 14 years.

I do the set back at night and when we are away in the day time.. For our Minnesota winter, I only pay a $54 a month budget plan gas bill. I have all gas appliances on the house w/ 3 of us.

Gas must be really cheap in Minnesota! I pay $262/month (OK that's just Canadian dollars!) on a budget plan (and my water heaters, cooking appliances and dryers are all electric).

Apparently, gas is more expensive here in Quebec than elsewhere in the States or the in rest of Canada. But gas is still supposed to be cheaper for heating than our relatively cheap electricity (85% of households here use electricity for heating vs 3% for natural gas mainly because it's not widely distributed in Quebec). I don't have a very efficient boiler (82%) so there shouldn't be a big difference between gas and electricity in my case.

How much gas do you use during a year?
I used about 3500 cubic meters (or 123601 cu-ft) of gas this year (heating from October 15th to May 15th) to keep the temperature to an average of 65-68° (and I keep my garage at the minimum setting on the thermostat which is 50°).

Where I am its only propane and pay thru the nose for it. 4 bucks a gallon to top off my tank which runs 2 gas heaters, used mostly in spring or fall and a gas stove, because I dont use enough gas to get a discount. No natural gas here. I have an oil boiler for heat and hot water with the original Honeywell thermostats set at 55 down and 65 up, never touched and 2 330 gallon oil tanks that last me a full year. Last year it took 570 gallons and I bet this heating season will go up.

Here's a Dutch ad from 1976 with a semi-automatic Honeywell. It had two temperature options and with the round dial you chose the hours you wanted the lower temperature. IIRC there was a programmable version too.

 

[philr]

This Semi-Automatic Chronotherm is the equivalent of my older Semi-Automatic T-832A thermostats. It has a mechanical 12 hour setback timer for systems that didn't have the required extra wiring to power the electric clock version.

I think

Henry Dreyfuss was the designer of that Honeywell...

 

[philr]

Henry Dreyfuss designed a few things for Honeywell including the round thermostat.

 

[philr]

One of the thermostats I have at home is the early T86 model like the one pictured on the box in my previous post (for the current electronic round thermostats), I also have Tap-Lite switches that were also designed by Dreyfuss, it's shown on their boxes.

 

[supersuds]

I've never seen a Taplite, but they look neat!

 

[circlew]

Henry Dreyfuss' most well known designs are the Western Electric 302 & 500 series telephones.

My house was built in 1952, and I always thought the Honeywell round thermostat was original to it, but above it says it was introduced in '53. Perhaps the original owners changed it out, or maybe my parents did when I was very young (we moved there right after I turned 2). A newer model with sub-base was installed when we got central air in '74.
