Does selected thermostat still control furnace if alarm battery is out and unit is unplugged?

I would think it would not as it would defeat the purpose of having the unit wire in to the thermostat(s).

Because my builder ran only 4 wires from the thermostat to the furnace, the fan is always on auto. But regardless, I have seen nothing that would allow you to program the fan only.

No, I just wired it to the thermostat that was wired directly to the breaker. Just like your furnace thermostat.

This is a wired thermostat. While the unit does have internal batteries, I believe that they are designed for backup since the primary power should come from your system.

Since I have never left the burner unattended, I can't answer that - it will set off an alarm if a pan is removed and the burner is left on -

Hi Claude, This thermostat opperates on DC current. It is powered by a transformer on your furnace that converts your 120V AC corrent to 3 volts DC current. (You already have that transformer in your furnace. It operated your previous thermostat.) It also has a 2 AA Battery back-up in case the power goes out. Your local power companies Load Control Device will have absolutely no effect on this unit. Gil PS - it is a great thermostat. Easy to program and works like a dream.

The C wire provides the power for the thermostat. The batteries in the unit are only for backup purpose when your power goes out. You need to get new wiring put in from your unit to the thermostat location with a C wire.

Yes, the unit will remember the settings without power. Mine has been unplugged for 3 months and it remembered the settings I last used for the set point temp and the differential range all in the proper units.

Absolutely not. Unit operates when plugged . Once you unplug ,if turned on ,starts operating using the batteries.

It has a battery for memory back up, but it runs off the C wire. Be sure your thermostat setup has a C wire.

For me there was one already installed to control a fan. The existing one went bad and locked into full power so I replaced it. There was three wires from my fireplace. One is power that is looped with a thermostat and the other is a neutral. Should be simple swap out, resolder the wires and it's ready to go.

Cannot run on batteries; this is VERY complicated to install because of the remote control. The thermostat was easy, but I had to disconnect it because of the module that has to be connected to the furnace. Had 2 plumbers tell me to call an electrician. The electrician is still reviewing the book!

When power goes out the thermostat holds the stored information for a while. If the power is out for extended time period then information is lost. This is as accurate as I can offer it as I've never timed it.

Hello Enairo, the thermostat operates on two AA batteries, not included, and the wiring is low voltage with connects to a control board which turns the heater or air conditioner, on or off. This control board is were the AC voltage is connected, it is not connected to the thermostat. Hope this answers your question.

The unit has a battery in case you lose electric power, but they are also connected to your house's electric wiring so the battery doesn't need to be replaced so often. In addition, when one smoke alarm goes off, all the smoke alarms in the house go off. This is important as I have a smoke alarm in the basement that I might not hear from some of the bedrooms if they all didn't go off together.

The thermostat requires a two-wire cable to run 24 volts to the thermostat location. It cannot run on batteries like the other accessories, which require no wiring. I didn't find the wiring difficult. I just opened up the furnace and made sure that the G terminal on the furnace was connected to the G terminal on the wiring interface, etc. One tip - hook the thermostat to the wiring interface with a short length of two-wire cable while setting everything up to prevent running up and down the stairs a couple dozen times. Once everything is working, then turn the power off and install the thermostat at its permanent location. The thermostat requires a two-wire cable to run 24 volts to the thermostat location.

Well the thermostat does turn the unit on or off depending on the ambient temp.
