Should I have 24 volts at thermostat?
Should I have 24 volts at thermostat?
24 volts is a safe voltage to work with and you shouldn’t even have to touch the wires. You can determine the voltage with the model number of the thermostat. It’s pretty much a given if you have a conventional forced air gas furnace, heat pump, or even oil heat then you likely have a 24 volt control on the wall.
Do thermostats use AC or DC?
Yes you are absolutely correct, typical Heating and Cooling thermostats operate at 24 volts AC. If we said DC somewhere that was a mistake. We do make a distinction between line voltage which is 120 V AC and the thermostat which powered voltage reduced by a Transformer to 24 V AC.
Which thermostat wire is 24v?
C-wire
A C-wire, or a common wire, runs from your low voltage heating system (24v) and carries continuous power to your thermostat.
Will a 24v thermostat work on 12v?
Most any battery operated thermostat will work for that system. You would only use the R and W connections on most units. You need to find something electronic, battery powered with relays – the lower voltage might cause problems with triacs found in cheaper t-stats.

Where does the power come from for a digital thermostat?
Power for a digital TT comes from one or at most two sources: Some thermostats also use a backup battery to remember settings when someone has turned off power or there has been a power outage. If the batteries are dead that’d be a second reason for a blank display.
What kind of power does an RV thermostat use?
Household thermostats normally run on 24V AC power but RV thermostat runs on 12V DC. If it is battery operated, not just battery backup, then the thermostat uses the internal battery to power the display and relay not external incoming power.
