I need a new thermostat. I see that there are a zillion out there. I
*think* all I need is separate AC/heat(gas) temp settings and perhaps
some kind of late night setback. And, reliable, so I can lock it down
and forget about it. It's going in the rental.
Does just about every digital fit those needs, or are there models to
either avoid or seek?
Most of them runs on battery or battery back up. A set of battery lasts
more than a year. Stick with name brand like Honeywell, you'll do just
fine. I use Honeywell wireless programmable one.
As Tony said, they either run on batteries that last several years or
power via the thermostat wires with battery as backup. Powering
via the thermostat wires requires
that you have a "common" wire at the thermostat, ie a return current
The lockbox you linked should fit just about any thermostat available
the only issue would be some huge one not fitting....
But.... I'd reconsider the locking. I'd find any rental that didn't
me to control the temp unacceptable..... Not only in regard to temp,
but how do you know when they want it setback at night or not?
Suppose someone is sick and wants it warmer one night? Or there
schedule changes..... Lock it and I see a LOT of trouble coming,
like you going over frequently to adjust it for them.
An intermediate solution might be a thermostat like the Honeywell
VisionPro. They aren't cheap, but you can get some good deals on
Eay. I just got a used one that is a multi-stage for $45. Would not
be my choice for a rental unit, but.... they have
an "installer menu" that takes a special key sequence to enter. In
that menu, you can set limits on the max heat settting allowed and
the min cooling temp allowed.

My understanding is that Honeywell is licensing out their name, with no
direct connection to design or manufacturing. At least my Honeywell
space heater is that way. That makes me suspicious, as the heater is a
bit of a dog.
That is lesser problem because whoever took the license has to maintain
quality standard. Otherwise they lose the licensing deal. Lot of us look
down on Chinese products but they just produce per specs. They can make
things as good as any. It is all matter of product specs. I retired from
Honeywell(from different division). When I switched to wireless, stat. I
sold my used Vision Pro 8000 to a guy and later he phone me asking if I
can sell more. He said he liked it very much.
Advantage of wireless is I can move it around the house if I want to.
Vision Pro has several models which will fit any situation.
I have to move my temp levers twice a year. The tenants would like it
better if they didn't have to set it more than once, and if Jeff is
paying for the heat or cooling, he'd like it better too
I bought one 22 years ago that is semi-electronic. A digital clock
keeps track of the time, but there is a mechanical slide switches for
the two temps (one degree increments) and another nech. slide switch
for the one or two setback start and stop times each day (15 minute
increments), and dip switches for M-Su to choose which days get one
setback period and which get two. Working fine for 22 years**.
The one thing it doesn't have is separate policies for summer and
winter. In the winter the daytime temp should be about 68, or in my
case 67. In the summer, 72 is apparently cool enough.
**I kept the original thermostat, which goes back in place before I
show the house, if I decide to take this one with me whan I move.
The contractor put a White-Rogers 1F85-277 in our home when we built
it but it is probably overkill for you because it is set up to run two-
stage air and heat systems. It sells for around $70 on Amazon We had
a similar, but similar unit in the last house that was about 1/2 that
price and provides all of the basic setback and thermostat setting
tolerances. If you don't have two-stage you should be able to get a
pretty basic programmable for $20-30.
And if you program it for setback during the night, or day (if you are
gone) it WILL save you money.
