Common Support Questions


While WarmlyYours electric radiant floor heating systems are typically installed by your floor covering contractor, a licensed electrician is recommended for the final thermostat hook-up. With every quote, we provide an Installation Plan layout, together with an electrical plan that has all the info required for the electrician.

Please keep in mind that you must check your electric floor heating system with a digital ohmmeter in conjunction with a Circuit Check™. Take an initial reading as soon as you take the product out of the box to verify that it is within -5% / +10% of the values stated on the product’s label. This will give you a basis of comparison for future readings. Take a second reading once you have positioned the system to match your custom installation plan. It is also advisable to take an additional reading in the middle of the tile installation, just to make sure that the Circuit Check™ is doing its job. Then, take a final reading when you are finished with the floor installation and are ready to hook up the thermostat.

The Circuit Check™ is a tool developed by WarmlyYours to give you peace of mind and ensure trouble-free installations. Simply hook up the cold leads to the tool while you position the system to match your custom installation plan.

The Circuit Check™ will continuously monitor the continuity of the circuit during the installation of your system and during the installation of your flooring. The Circuit Check™ beeps immediately when a short in the system is detected, alerting you to a potentially damaged cable in the area you are working, before you lay the tile over the electric floor heating system.
 The WarmlyYours technical support team is available 24/7 to provide assistance if the alarm sounds, or if you would have any questions during your installation.

Yes, in most cases, an electric floor heating system can be effective as a primary heat source. However, our TempZone™ and Environ™ systems are most commonly used as a secondary heat source, providing floor-to-ceiling radiant heat to any room in your home where you desire more warmth and comfort.

If you are considering electric floor heating for an addition to your home, such as a sunroom where you have no other source of heat, WarmlyYours offers an innovative online tool which calculates approximate heat loss. This tool can help you to determine if a WarmlyYours’ electric radiant floor heating system will provide your desired comfort temperature throughout the year. You can access the Heat Loss Calculator or you can call us at (800) 875-5285 and a Customer Service Representative will make the calculation for you.

The temperature of your floor can range anywhere between 75°F to 95°F. The floor's actual temperature will depend on a number of factors including the amount of heat loss that the room experiences as well as the room’s configuration. For instance, the warmth contained in a two story entry way would likely be less than that of a smaller, more enclosed area such as a bathroom. In a bathroom that is located on the second floor of your home or over another floor in your home that is typically heated, the temperature of your heated floor should easily reach a comfortable temperature of 85 degrees Fahrenheit, if the electric floor heating system is installed correctly. For the heat loss calculation for your specific room, you can access the Heat Loss Calculator or you can call us at (800) 875-5285 and a Customer Service Representative will make the calculation for you.

Electric floor heating works by having an electric heating cable installed underneath the flooring (embedded or floating, depending on the system and floor type), which is then wired to a special thermostat (either one specifically designed for electric radiant floor heating, like a WarmlyYours’ nSpiration Series control, or a third-party thermostat). When turned on, the heating cable emits heat upward through the flooring which is then radiated throughout the room, heating all solid surfaces.

Cause:

Some WiFi routers limit the number of wireless devices that can connect to the Internet.

Solution:

To test whether this is the problem, shut down one of the other WiFi-enabled devices in your home. Once that device is completely shut down, try once again to connect your WiFi Touch Thermostat to the network. If the WiFi Touch Thermostat connects successfully, 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.


Cause:

Some WiFi routers broadcast a stronger signal that the WiFi Touch thermostat.

Solution:

If this is the case the WiFi Touch thermostat can see the WiFi router – but the WiFi Touch thermostat cannot reach the WiFi router.


Cause:

Maybe your WiFi router requires a restart/reboot

Solution:

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 such problems. While most routers simply have to be unplugged and then plugged back into their power source to restart them, you should refer to your router’s documentation for specific instructions.


Cause:

Maybe your WiFi router firmware needs to be updated

Solution:

Contact your ISP or the router manufacturer for instructions on how to update the firm


Cause:

Other devices are interfering with the wireless signal

Solution:

Try turning off other wireless devices (Bluetooth, WiFi, wireless phones/cameras) that may cause interference, then test the WiFi Touch Thermostat’s network connection.


Cause:

Your WiFi Touch Thermostat needs a user reset

Solution:

Restart your WiFi Touch Thermostat. To restart the WiFi Touch Thermostat, go to Menu/User Settings/User Reset and select “Reset Thermostat”. Once your WiFi Touch Thermostat has restarted, go to Menu/WiFi/Weather Settings and try to connect your thermostat again.

Important! It is imperative that you make a note of the “Distributor ID” found in the thermostat under “Menu/User Settings/Information” before performing a “Factory Reset”. The thermostat will not operate without it.


Cause:

Insufficient WiFi signal

Solution:

Try connecting another device, such as your mobile phone, to your wireless network. Stand next to your WiFi Touch thermostat and access your phone’s wireless network settings. If the wireless network signal cannot be detected by your phone, or is very weak, other devices may also have trouble connecting to the network from that area of your home. You may be too far away from your WiFi router or there may be a problem with it. If you are too far away from your WiFi router, you can purchase a WiFi signal repeater which will improve the range of the WiFi signal in your home for all devices.


Cause:

Your WiFi router has insufficient security

Solution:

With so many home devices now connected to the Internet, we want to make sure that your WiFi Touch Thermostat is connected to a secure network so that hackers cannot gain control of devices in your home. WiFi routers utilize two main types of protective encryption: WEP and WPA. WEP is the original form of encryption and it offers very little security.

Hackers can very easily break into your wireless network if your router is set up for WEP encryption. WEP encryption 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 networks. Your WiFi Touch Thermostat currently supports WPA and WPA2 encryption only. If your router was manufactured after 2003, you should be able to change the setting from WEP to WPA by following the guide in the link: (http://www.tech-faq.com/how-to-change-wep-to-wpa.html). Your WiFi Touch Thermostat can still control your floor heating system without wireless network connection. As the best course of action, The manufacturer recommends that you upgrade your security settings to properly protect your network from hackers. If that is not possible, contact your network administrator.

The default is 10k.  If this is a new installation, that is the answer.  In the very rare occasion that this is replacing a 12 year old or older Energy stat (square OJ Microline from before 2010 with red and green sensor wires), choose 12k.  If this is a replacement for the other 99% of the other thermostats we sold (Honeywell TH115 and TH111 thermostats), 10 k is the value.

Always start with the default 10k and change later if needed.
