@@ResideoSupport Of course I have already pressed mode button and it goes from heat to off to heat again without the cooling indicator ever coming on. It is already too late the customer purchased a Sensi and I installed it. I will be seeing that customer again and maybe he'll have the stat still.

Hello Jake, as you might know our thermostats are compatible with different system types. This thermostat might being configured to work on a heat only system. For further references, we recommend to check on the thermostat's configuration options so you can choose the correct one. Feel free to contact us if you have questions on how to access this menu. -Alex

Thank you for reaching out. If the thermostat original registration was made in the TCC portal and it is imported to the Resideo app these options are available only at the original platform. Some models will not display that option as the permanent or temporary hold are made directly from the main screen of the app where the thermostat setpoints can be adjusted. -Cesar

Hi, we're happy to help! Could you please provide us with the complete model number of your thermostat? This info will be located on the back side of the thermostat itself. It’s a number that starts with RTH, TH, or CT​. -Jerry

@@ResideoSupport TH1110D2009

Thanks. Do you feel any air at the vents when you set the mode to cool? -Jerry

@@ResideoSupport none. It won’t even come on anymore

Hello, A T-L. Thank you for contacting us. We are happy to solve all your questions. This is a non-programmable thermostat, which means the temperature you set will be hold until you change it back. Also, this model of thermostat has the Minimum and Maximum Heat/ Cool Setpoint feature which will allow you to lock the temperatures. You will need to access to the installer's setup menu to be able to customize these. Please, reach at us on Facebook so we can guide you step by step with the process. You can find us a "Resideo Pro" or "Honeywell Home". -Alex

Hi, thank you for reaching out. If the heating system has only 2 wires (R-W) and there is no C terminal at the board the only way to supply the Common/C wire would be to use an external 24V transformer wires to the RC and C terminals of the thermostat. -Cesar

@@ResideoSupport so does the one wire support both the fan and cool function independently?? I don't want any trade secrets from you on how the device operates, I'm just looking for assurance that this device can perform the task of two wires using just one wire. As long as I have the ability to control my furnace fan alone without having to turn the A/C on then I don't care how it does it.

Hello Steve! Thank you for contacting us. Yes, the K label in the C Wire Adapter can control the Fan and the compressor independently. It will provide you two independent wires that you can connect to fan and compressor separately. -Alex

@@ResideoSupport excellent. Thank you Alex. That is all I needed to know. Hope you have a great afternoon. 😊

Glad to help, Steve! Have a great day! -Alex

Hello, Quang! Thank you for contacting us. We are happy to help you connecting your thermostat to Wi-Fi. Sometimes, the home wi-fi network interrupts the connection between your thermostat and cellphone and doesn't allow the website to load.

If you are unsure how to disable the "Auto join", feel free to contact us at 1-800-633-3991, or through Twitter and Facebook under Honeywell Home. -Alex

Hello, Jigar. Thank you for contacting us. The instructions above does not apply to the T6 Pro Z wave.

Hi Onur B. Thank you for reaching out. Yes, the binding and troubleshooting operations are the same for both the devices. -Elena
