The GLAS smart thermostat by Johnson Controls is the perfect blend of form and function. Featuring a vibrant translucent OLED touch screen, the clearly smart thermostat maintains a comfortable space while it saves energy and monitors air quality. For easy voice control, GLAS works with Amazon Alexa and Google Assistant. The GLAS by JCI smart thermostat app allows you to easily tweak the temperature from anywhere.
Q: is the C-Wire required for this?
A: Short answer:yes. All smart thermostats require a c-wire to some degree. There are ones that claim they do not require one (nest.)However they draw the power they require by essentially short cycling your furnace when it is not in use, which may or may not be an issue depending on your situation. There are ones that come with power extener kits (ecobee) that people seem to like. There is always that garbage trick of jumping wires and sacrificing your fan control, or paying someone $300 to run new wires. However there is always the reasonable solution of purchasing an adapter kit for like $25 and that will be the easiest, cheapest, and you don't sacrifice any functionality. So if you really want a specific thermostat don't let a 4 wire system hold you back.
Q: Does it accommodate a 2 stage furnace with modulating fan.
A: The Glas can handle a two stage system and it also have an AUX out put as well but I would call Glas directly if the aux can be use to control the modulating fan
A: Hello Ed. I had a similar problem a few days ago. The internet was having issues and the thermostat disconnected from the modem. During that time the "Outside" temperature was not showing. I went into Settings->General->Wifi->Forget this network. I added the Wifi network again and that fixed the problem. Try it and let me know if it worked. Good luck.
Q: do you have to have Wi-Fi present to use this product?
A: On the last storm I lost the internet and the Glas continued to work but was not able to control the Glas via app / cell. Not sure if you need the internet during the initial set up. Best to call Glas and ask, you can reach them at 1-833-297-4527.
Q: Thermostat will not come out of test mode.
A: They stopped supporting the app and now the thermostat is useless.
A: No. The thermostat will no longer connect due to JC discontinuing the product. Therefore they will no longer support any updates, the app will no longer function and will no longer connect to wifi. This smart thermostat is not smart anymore and is basically an expensive standard thermostat.
Q: Will this work in my travel trailer?
A: undefined
