THANK YOU FOR CHOOSING NUHEAT SIGNATURE!
You have chosen the most advanced thermostat to control your
Nuheat electric floor heating system. This manual will cover each of the
features of the Nuheat SIGNATURE thermostat.
INTRODUCTION

5SIGNATURE OPERATING MANUAL
The Nuheat SIGNATURE thermostat features
a series of diagnostic tests to confirm the
thermostat is installed and functioning properly.
The System Tests option is available the first
time the thermostat is connected to power or
after a factory reset is initiated.
The Nuheat SIGNATURE thermostat features a Setup Wizard to guide you through
the basic setup process.
The Setup Wizard is available the first time the thermostat is connected to power
or after a factory reset is initiated. Refer to section 6 on page 17.
The Nuheat SIGNATURE thermostat has a built-in GFCI (Ground Fault Circuit Interrupter).
The GFCI protects against risks of electrocution caused by a current leakage. If the current
leakage exceeds 5 mA, the GFCI will automatically be triggered, thus cutting power to the
floor heating system. To indicate the fault, a message will appear on the screen informing
you of the fault. To reset the GFCI, press the button on the right side of the thermostat.
If problem persists, contact Nuheat at 1.800.778.WARM(9276).

SECTION 8: WIFI TROUBLESHOOTING
I CAN’T CONNECT TO MY WIFI NETWORK
Cause Solution
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.

SECTION 8: WIFI TROUBLESHOOTING
I CAN’T CONNECT TO MY WIFI NETWORK
Cause Solution
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 (http://www.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.
