How do I connect my Aprilaire Wi-Fi Thermostat to the Internet?

Please view the Start Up Guide for connection instructions. This guide can also be found in the packaging for your thermostat.

How do I find the password to my router?

The password is usually set when the router is setup by a homeowner or internet service provider. If you do not know the password, check the bottom of the router, the router owner’s manual or any service papers from the install process. If you cannot locate the password, you will need to contact your router manufacturer. Aprilaire does not have this information.

Is the MAC ID case sensitive?

No. You can enter the MAC ID with upper or lower case letters following the correct format [Ex: b4.11.22.43.4E]. The MAC ID should populate on its own when connecting a new thermostat, if the device is added following the directions in the User Guide.

Can I connect my Wi-Fi thermostat to my guest network?

It is recommended that you connect this thermostat to your home network. If you wish to connect to a guest network, you many need to contact your router manufacturer for assistance.

I have followed the connection instructions in the User Guide but still have no connection. What should I do?
