HBX SNO-0600 SNOW MELT MODULE
This manual will help with the installation, parameter setting,
troubleshooting and general maintenance requirements for
the controller. To guarantee the safe and reliable operation of
this control, you must rst read this manual in detail and take
particular note to any and all warnings or caution directives prior
to connecting to AC power. Please consult and install the heating
appliance in accordance with manufacture’s recommendations.
DESCRIPTION
The Wi-Fi enabled SNO-0600 Snow Melt Control operates Hydronic
heating and electric equipment tom melt snow and/or ice from
driveways, ramps, and walkway surfaces. The control consists
of numerous exceptional features including settings for snowfall
intensity as well as an adjustable delta T. The control can operate
a single boiler and also control a main system pump to supply heat
to the slab. The control allows for multiple mixing options including
injection, oating action and modulating (0-10 VDC).
The SNO-0600 now features weather forecasting in its programming.
This allows the control to receive your local weather forecast to turn
on your system in the anticipation of a snow storm. This will reduce
the need to idle your slab all the time in the winter and save you a
signicant amount of money on your utility bills.
Optical Snow Melt Sensing
The SNO-0600 control works in conjunction with the SNO-0110. The
snow sensor utilizes optics rather than continuity based on/off sensors
typically used by other manufactures. The sensor feedbacks snowfall
rate and intensity while also providing slab temperature. This sensor
technology allows the user to ne tune the type of conditions that
initiate a snow melt mode on the control.
Remote Access Anytime, Anywhere
Used in conjunction with the free HBX Sensorlinx™ mobile app,
users can control and monitor their snow melt system remotely from
there smartphone devices with the ability to set snow fall rates,
system targets, monitor equipment operation, and adjust weather
forecasting demands.
This control can also function as a stand
alone system without WiFi capabilities.
FEATURES
• Remote access for Apple and Android
devices via Sensorlinx mobile app
• Full-Colour touch screen display
• Weather forecasting
• Optical Snow Melt Sensing Technology
• Pre-Set Snow Fall Intensity Settings
• Boiler enable
• Modulating Mixing (0-10vdc)

SYNC CODE: Sync code of the SNO-0600.
SENSOR VOLTAGE: Displays the snow melt optical
sensor voltage. This can be used for troubleshooting
with HBX tech support.
SENSOR CURRENT: Displays the snow melt optical
sensor current. This can be used for troubleshooting
with HBX tech support.
SENSOR RESISTANCE: Displays the snow melt optical
sensor resistance. This can be used for troubleshooting
with HBX tech support.
REAL TIME SNOW: This allows you to view what the
snow melt optical sensor is currently sensing as a snow
fall rate.
SNOW RAW DATA: This is information for the snow melt
optical sensor. This can be used to troubleshooting
with HBX tech support.
WIFI NETWORK: Displays the current SSID network that
the control is connected to.
NETWORK PASSWORD: Displays the current SSID
network password that the control is connected to.
WIFI STRENGTH: Displays the current SSID network
strength connected to.
FUNCTION TEST: This setting will allow the user to pre-
test the control during setup. It will set the outdoor
temperature 10°F and the system temperature to 80°F
so the system will test on initial installation and/or in
warmer months. When set to on, the control will stay in
this mode for a period of 30 minutes.

DESIGN TEMPERATURES
These settings are used to congure the design
temperatures of the snow melt system.
DELTA T: Set this temperature to the ∆t you would like
in the system. This will calculate the system target. The
target is calculated by using system supply and system
return temperatures: System Target = System return +
System ∆t
(2°F to 100°F) Default: 25°F
MINIMUM SYSTEM TEMPERATURE: Set this to the
minimum temperature you would like your entering
water temperature in the slab to be. This is for the low
temperature system loop.
(32°F to 210°F) Default: 50°F
MAXIMUM SYSTEM TEMPERATURE: Set this to the
maximum temperature you would like your entering
water temperature in the slab to be. This is for the low
temperature system loop.
(32°F to 210°F) Default: 120°F
WARM WEATHER SHUTDOWN (WWSD): This is used to
set the outdoor temperature in which the SNO-0600
will go into WWSD. If the outdoor temperature rises
above this temperature, the control will turn OFF. In
WWSD the boilers and all pumps will shut off, and slab
temperature will not be maintained.
(2°F to 55°F) Default: 40°F
COLD WEATHER SHUTDOWN (CWSD): This is used to
set the temperature in which the SNO-0600 will go
into CWSD. If the outdoor temperature dips below
this temperature, the control will turn OFF. In CWSD
the boilers and all pumps will shut off, and slab
temperature will not be maintained.
(-41°F to 40°F) Default: 0°F
USE WEB OUTDOOR TEMP: This setting can be used for
outdoor temperature reading via the web instead
of installing an outdoor sensor. The control must be
connected to a Wi-Fi network and the user must set
the controller to a building via the Sensorlinx mobile
app for this setting to work.
(ON/OFF)
If the control disconnects from the Wi-Fi Network the
control will maintain the current outdoor temperature
for 2 hours. After 2 hours elapses the control will go into
WWSD.

SLAB SETUP
These setting are used to congure your slab options.
IDLE TEMPERATURE: This is the slab setpoint when there
is no snowfall present, and the control is operating
between the WWSD and CWSD parameters.
(-40°F to 80°F, OFF) Default: 20°F
TO TURN IDLE TEMPERATURE OFF, SET TEMPERATURE BELOW -40 °F OR
ABOVE 80 °F.
MELT TEMPERATURE: This is the slab setpoint when
there is snowfall present, and the control is operating
between the WWSD and CWSD parameters. This
setpoint can also be triggered by a Force Melt either
manually or through Forecasting.
(2°F to 100°F)
MELT TIME: This setting allows for the system to stay on
even after no snow is present. This will melt any residual
snow that has accumulated and not melted. This time
is also used when a force melt demand is given. Once
a force melt demand is given the control will stay in
MELT mode for this amount of time.
(1H to 99H) Default: 3H
SENSOR LOCATION: Set this to INT when the Snow/ Ice
Optical Sensor is mounted in-slab, or set to REM when
mounted remotely.
(INT or REM) Default: INT
USE SNOW SENSOR: This feature allows you to enable
or disable the snow melt sensor functionality for the
purpose to use the snow melt sensor remotely on
weather forecasting.
