I have this same unit in my condo and just recently the programmable
mechanism started making a constant buzzing noise. I was wondering if you
knew of any place that might sell a replacement for the part? If not, is
there any way to cut power to the programmable unit and just turn the a/c
and heater on manually?
Thank you for posting this! It helped us a lot.
I have the same thermostat but going to change it to Nest thermostat would
it work?
@VICNASTY1989 I didn’t think you’d intentionally break the mercury and I
wouldn’t either.
Have you ever heard of Ceil Heat (ceiling heat)? It was popular in the
1950’s and early 1960’s and did a pretty good job of heating the house. The
thermostats for that weren’t nearly as complicated as what you have there.
Nope, they’re some of the best! -Thanks for watching!
is it dangerous to take the mercury tube out?
@auaiao9 Yes I have heard of that- I was just talking about a oil or gas
burning hot water system. Its really cool yours was electric. I would think
the system would have a 120V line voltage snap switch thermostat? Must of
cost a fortune to run though.
i was reacently useing one of these on a homemade steam space heater, it
worked awsome, i will try to post a vidio about it.
@VICNASTY1989 yes it is. 🙂
@auaiao9 Thanks, I’ve cleaned it up a lot, but it is in fairly good
condition. I wont intentionally break any thermostat or thermometer to play
with the mercury- but I do have mercury samples in a container from other
devices that have accidentally broken (fever thermometers, contact
switches, etc.)- I really don’t enjoy chasing thousands of tiny silver
balls all around the floor with an index card but, it is really amazing to
play with.
Have you got any other thermostats in your collection besides the ones in
your video’s?
@VICNASTY1989 No, the type I’m talking about is electric strips in the
ceiling. It’s radiant heat from above, not the floor.
@airconguy1 Youtube is acting weird, I don’t think my other comment went
through. But, to use the energy saving program modes, you set the blue
slider to the minimum temp you want the system to reach and the red one to
the max. temp you want it to reach.
@auaiao9 Yeah, I dont do that- but it is fun to play with!
i have a chronotherm just like that, got it off a boiler change job, very
cool with the analog clock and pins for heat and reduced temp.
Is this high voltage thermostats p
@stickystick105 No, if it doesn’t break. But I do not recommend doing this
because mercury is dangerous- and more or less a real headache to clean up
(you have to join millions of little silver blobs running all over the
floor back together)- Trust me mercury is the best thing ever but it sucks
to handle- LOL!
It’s clean for the age that it is. You gonna roll the mercury around in
your hand??
@airconguy1 I just want to say I am judging off of memory with how this
works (we haven’t used this thermostat in 13 years). As I remember when you
have the system set to heat you split the red and blue sliders with blue
being the minimum temp you want it to reach before ignition and the red
being the max. temp you want the system to reach. With cooling- you reverse
the purpose of the sliders; blue now equals min cooling temp and red equals
max temp before the system turns back on.
@auaiao9 I have heard some tell of radiant ceiling heating (that’s what you
are talking about right?)- hot water tubing run above a ceiling for heat.
My dad’s Levvitown, P.A. house had something like that in the late
’50s-early ’60s but it was radiant floor heating below the asbestos tiles-
they had that retrofitted in the early 1970’s to radiators. I agree that
older thermostats are much easier to set and control- not like the new
digital ones.
@airconguy1 To use the unit as a regular thermostat, you disengage the
clock by taking all the pins out and sliding the red/blue sliders together
so they only point at a specific temp. With your question of which mode
turns on first with the clock- it depends on which color is in the circle
window in the center of the thermostat’s face cover- red/blue. I hope that
answered your questions- and the other videos will be up shortly (they take
awhile to upload with my slow internet connection)
I have a few more, plus I have been meaning to do more of these HD
Thermostat collection videos, so they should be up soon.
