| Wrong password | Try entering your password again. Be careful to enter uppercase and lowercase letters, numbers and symbols as needed. The Nuheat SIGNATURE thermostat can switch between three different keyboards to enter these characters. |
| Your network name is hidden | If you have another device connected to your WiFi network such as your mobile phone, stand next to your Nuheat SIGNATURE thermostat and go into your phone's WiFi settings to see if the network name is appearing. If you do not see the network, it could mean that your network name is hidden. If your wireless network is hidden, it means you’ve chosen to not have the network name broadcasted to devices. In the WiFi Settings on the Nuheat SIGNATURE thermostat, select Other at the bottom and type in the name of your network (aka SSID). Then enter your password when you are prompted. |
| Thermostat is too far from WiFi router | Try connecting another device such as your mobile phone to your WiFi network. Standing next to your Nuheat SIGNATURE thermostat, go into your phone’s WiFi settings. If the WiFi signal cannot be detected or is very weak on your phone, it means other devices may have trouble connecting to the network from that area of the home. This means you may be too far away from your WiFi router or there may be a problem with it. If your WiFi router is too far, you can purchase a WiFi signal repeater which will improve the range of the WiFi signal in your home for all devices. |
| Insufficient security settings on your WiFi router | With so many home devices now connected to the Internet, we want to make sure our Nuheat SIGNATURE thermostats are connected to secured networks so that hackers cannot gain control of devices in the home. There are two main types of encryption or protection available through wireless routers; WEP and WPA. WEP is the original form of wireless security which offers very minimal security. Hackers can very easily break into your wireless network if your router is setup with WEP encryption. It was replaced with WPA encryption in 1999 and WPA2 in 2006. WPA is a security protocol that makes it much more difficult to break into the networks. The Nuheat SIGNATURE thermostat currently supports WPA and WPA2 encryption only. Nuheat is releasing a version of the SIGNATURE that will support WEP in the coming months. If your router was manufactured after 2003, you should be able to change the setting from WEP to WPA (httpyAvww.tech-faq.com/ how-to-change-wep-to-wpa.html).Without a WiFi connection, the Nuheat SIGNATURE thermostat can still control your floor heating system. Nuheat recommends the best course of action is to upgrade your security settings to properly protect your network from hackers. If that is not an option, please contact Nuheat at 1.800.778.WARM(9276). |
| Too many wireless devices connected to your network | Some WiFi routers have a limit on the number of wireless devices that can connect to the Internet. To test if this is your issue, shut down one of the WiFi enabled devices in your home. Once that device is completely shut down, try again to connect to the network with the Nuheat SIGNATURE thermostat. If the Nuheat SIGNATURE thermostat successfully connects, consult the documentation for your access point or contact your Internet Service Provider (ISP) to find out if you can increase the number of simultaneous connections to your WiFi network. |
| WiFi router requires a restart/reboot | The problem might be with your router (even if your other wireless devices are still connected). A simple restart of the router will usually resolve these types of issues. While most routers just need to be unplugged and plugged back into their power source to restart them, you should refer to your router’s documentation for specific instructions. |
| WiFi router firmware needs to be updated | Contact your ISP or the router manufacturer for instructions on how to updated the firmware. |
| Presence of wireless interference | Try turning off other wireless devices (Bluetooth, WiFi, wireless phones/cameras) that may cause interference then test the Nuheat SIGNATURE thermostat’s network connection. |
| SIGNATURE thermostat needs a factory reset | Restart your Nuheat SIGNATURE thermostat. To restart the Nuheat SIGNATURE thermostat, go to Settings>Factory Reset and select Reset. Once your Nuheat SIGNATURE thermostat has restarted, go to Settings>WiFi Settings to try to connect again. |
