It is a battery operated unit but they last a long time and are easy to replace.

The thermostat seems to use a little power from the batteries at all times and needs new batteries about once a year.

If the batteries are dead the thermostat will not work. However the batteries last a very long time so change them on a yearly basis if you are concerned.

No it does not. Ac power plug only and batteries for backup in cast of a power failure. I believe the battery backup is good for about 8 hours. We are very please with this product. As I said before, it is a little tough to get the timer set right ( of course I am pretty dumb when it comes to these things ) but once it is working, you will almost forget about it.

No, it only Works grid tied. Once there is no power from the grid, it stops working. It is not for back up systems.

If you don't mind that the back light will not be constantly on, you can run this thermostat off of batteries.If you have the wire providing power to the thermostat, you can set the back light to stay on which is very nice at night. The batteries at this point provide backup, but then if there is no power, the fan in the house for the HVAC system wouldn't be working either. It's just there in that case to hold settings including the time and date.

Yes. Word of warning...if the power goes out, you will need to reset the timer. Also, this product lasted about one year and died on me. Did not replace with another. Went to Lowes and bought one that is digital and has battery backup ($25) seems to work great, but time will tell

Your power source is integrated into your thermostat wire. Its not a separate power source. Most HVAC systems have a 24v power integrated. The battery is just a back up and to keep your settings.

It is a thermostat and will apply power to what ever you have hooked up to at the temp you set it to. It will stay on as long as the temp is above the set point.

Yes, it would work as a thermostat, but it needs a 12 volt source; with this source, it works as a switch which should work, jim

Yes, but only if you don't connect the COM common wire to provide power to the unit if the batteries die. If at all possible, make sure to connect that wire so the furnace won't go dead when you need it most. It may mean running another wire from the furnace to the thermostat. But it's worth it in the long run.

It does not come with thermostat or on off switch. This needs to be connected to power supply by electrician and thermostat added as well.

No it does not. This unit is powered from the source just like the Thermostat in your home which is usually 24 v ac. This unit is basically a switch with no electronic parts inside. It does not care if it is AC or DC. The Temp controls the on and off of the furnace. This is basically a temperature sensitive spring inside the thermostat. This is as basic as it gets. It works for sure.

Yes. It turns on and off using the thermostat setting. I have had two other units over the past few years and this is definitely the best I have owned.

No battery backup built in but it uses the battery from the the alarm system. It has retained my zwave configurations after being disconnected. Most of the alarm programming is retained on your alarm system. IP address and such is usually DHCP.

The thermostat retains the last settings if that is your question. If power is out, your HVAC is out of commission anyway :-)

Batteries are a back up in case your power goes out to the circuit. It keeps the time and the settings you have programmed. As long as the electric is on, the batteries do nothing. It's when the power is off to the circuit is when the batteries take over to keep your settings on the timer. However the batteries will not turn the lights on or off. It only keeps your settings when the power goes off.

No. It does not have battery backup. During a power outage, it will need to be manually disconnected to allow opening or closing of the garage door.
