Alexa and Lennox Icomfort are communicating. If I ask to set the temperature to say 75 degrees, I get an answer that says "I can only set the temperature between 0 and 0.5 degrees... Help!!


I had the same problem and worked with Lennox Support to fix it. Just to be clear, here was my problem: After a new installation of a Lennox M30 iComfort Alexa enabled thermostat, I was trying to control the temperature using Alexa voice commands. When saying "Alexa, set [thermostat name] to 72 degrees", I would get the response "Sorry, I can only set the temperature between 0.5 and 0 degrees." Solution: login to your iComfort account (lennoxicomfort.com) using your computer or laptop (not a mobile device). adjust the temperature setpoint using your computer (in my case, I simply raised the temp setpoint 1 degree). confirm that the temperature setpoint adjusts at the thermostat. Now try to use the Alexa voice command to change the temperature setpoint. Magically, everything now worked. The tech on the phone said that the computer adjustment was needed to initiate voice command capability and commented that doing this via mobile (smartphone or tablet) would not work.

Your control may a defected relay to the blower under heating mode. If that is the case you will need a new control board or replay.

I have a lennox 2 stage gas furnace and a lennox XP15 heat pump controlled through the Lennox 7000 touchscreen thermostat. I want to disable the heat pump due to excessive noise due to lower temperature...


At tstat press options. Press installer setup. Yes, you are qualified. System settings, non heat pump. Gas/ oil heat. Save changes. That should do it with no wiring changes.

I replaced a Lennox DSL-450LX heat pump thermostat with a Honeywell RTH3100C. Everything works except the gas does not ignite when set to emergency heat. The Lennox was wired as follows: W = white wire Y1...


Hi, If indeed you do have a heat pump, there wouldn't be any gas involved as a heat pump runs on freon with a reversing valve and heat strips for aux and emerg. heat. For gas electric operation thermostat terminals are rc to rh with factory jumper. Red wire to either.W to W for Heat, Y to Y for cooling G to G for Fan. If you have a blue, you wont need it unless this is a commercial stat useing a common for the Led lights on the stat. The unit will get its 24volts through R terminal in combination with y,w,and,g. Cant be a heat-pump if you have a gas furnace.Wrong t-stat. You need a gas /elect stat. And on a 24volt programmable t-stat, the batterys are used for the program only.If the batterys die, than you will loose the program on most residential stats. On commercial stats with the common in play, when batters die the stat defaults back to the factory settings.If you had a Lennox heat-pump stat on a gas/elect unit, you need to change it. Someone was using what they had on hand. Let me know if this has helped you.I will be here if you need me. Sincerely,

DSL connection not being shared by Linksys RV042 Dual Wan router


Looks like your "modem" is actually a gateway, as is common with DSL devices. It's acting like a modem and a router. So you're actually connecting a router to your RV42. You could get this to work a couple ways.
1. Leave the modem acting like a router and configure the WAN connection on the RV42 as a static IP, and use the IP of the modem. You may also be able to use "obtain IP automatically" in the WAN connection. This way, the modem stores your PPOE information and just forwards the traffic to the RV42. Any devices behind the RV42 won't know the difference.
2. Configure the modem as just a modem (no routing). Your ISP should be able to talk you through this, but in the modem configuration you can look for what's usually called "bridged mode." Then you would enter the PPOE information in the RV42. This is my preferred method.
