I would like to replace my thermostat in my apartment with a digital
I don't have access to turn off the electricity to my HVAC system and
I don't want to involve the landland (I can always change back the
thermostat when I leave).
Do most thermostats run off of a 120v power control? Is there any safe
way to replace the thermostat without being able to cut electricity to

No. They run off of 24 volts. If you want to make sure, measure

All the thermostat is is a couple electronically controlled switches,
plus an internal microprocessor. You should be able to take off the
old one and put on the new one without touching any of the uninsulated
portions of the wires and without letting any wire touch any other.
Heck, some people change 110 volt fixtures without turning off the
If you do touch the wires, you probably won't be able to feel 24
volts, and it won't kill you.
If you let them touch each other, I don't think there is any pair that
will hurt anything. More likely it will start the heat or ac.
But now is the time to learn how to do these things wihtout touching
Make a detailed drawing of which wire is on which screw now, so you
can put it back before you leave, and so you'll be able to figure out
how to attach the new one.
yeah , right ,
short the wrong two together and he'll let the factory smoke out of the

leave it alone ,or call the landlord and have them kill the power while you
replace the stat ,
you'll be sorry !!!!!
About 30 yrs ago I heard a joke about semiconductors. The joke was that
they worked with smoke. If you hooked them up wrong or abused them the smoke
escaped and they stopped working. Hope that clears up your confusion.

BTW, when you snip everything the previous poster wrote, no one can
tell if your comment makes sense or not. Leave the part that you're
objecting to, and you'll have a much better chance of convincing
There's no more power/electricty/danger/problem in changing out a thermostat
than changing the batteries in some flashlights (24 volts, not 120).
Go for it.
Whether you'll like a programmable thermostat is another issue.
More likely 240, but then there would be an individual thermostat in
each room. My parents' house has this, as there were no other
utilities available when it was built. Heat is solely from large
woodburning stove and 240V resistive baseboards.
