The Venstar 1700 does not have batteries in it. It is powered by the red and common wires coming to the thermostat from the furnace or boiler. The venstars are usually very reliable. I would check the furnace or boiler and make sure it is sending out 24 volts to the thermostat. Sometimes a fuse blows on the furnace board or transformer goes out. Don Patterson
No, the power is supplied by the house wiring. Recheck the house wiring connections to the thermostat. If the power to the house goes out, there is a built in back up to remember your settings, but not to operate the thermostat. Fred D
You need the Comfort Call module (part ACC0433).
I did not use this w/ Wifi. I used this in conjunction with Comfort Call (a wireless receiver whose counterpart plugs into the phone line). Samir Patel M: +***.****
Unfortunately it is designed to work with matched wireless phone modem that is sold separately. We have two mountain cabins we use these on. They work perfect for our application. In my research, the wifi thermostats require a subscription and a fee. Hope this helps. Sent from my iPhone
I don't think so. I added the comfort call module so I can communicate remotely through the phone. This was the most effective for me since I did not want to dedicate/power a computer & router while I was away. I looked at the website to see if you could add an 802.11 module but didn't see anything. They do have a 365day usb programmable thermostat calendar module but don't think that is what you are looking for. There are 802.11 features for thermostats on the market though, I remember seeing them when I was looking for the phone controlled thermostats. Fred
