DESCRIPTION
Together the SNO-0110 (sensor & cable) and the
SNO-0111 (socket and cover plate) make up the
sensor portions of the HBX Snowmelt System. The
SNO-0110 snow/ice sensor is an optical design that
is capable of sensing snow conditions. This allows
the user to set a preferred starting condition for
the snowmelt system. The SNO-0110 is design to
be mounted in the slab however because of the
optical design it can also be remotely installed.
The SNO-0111 socket and cover plate allows for the
concrete, asphalt, etc. to be poured prior to the
installation of the Snowmelt Control, and the SNO-
0110 snow/ice sensor.
Only suitably qualied individuals with
formal training in electrical and HVAC
controls should attempt the installation
of this equipment. Incorrect wiring
and installation will affect the warranty
provided with this unit. Wiring must be
completed in accordance with the
codes and practices applicable to the
jurisdiction for the actual installation.

INSTALLATION AND WIRING
INSTALLATION:
1. Slab Sensor Location
Installing the sensor at the correct location in the slab is
critical for a properly functioning snow/ice melting system.
The sensor should be located where snowfall is normal and
not affected by surrounding buildings. Also, the sensor must
not be installed where standing water could accumulate
on its surface.
The sensor location should also be halfway between the
twoheatingpipesthatareinstalledintheslab(seegure
1). There is a thermistor built into the sensor that senses the
slab temperature at all times. Keeping the sensor away
from pipes in the slab ensures the accurate operation of
your snow/ice melting system.
a) Mounting the Socket and cover plate
When mounting the socket and cover plate in the snowmelt
slab use rebar mounted in the soil below to level the socket
and cover plate so that the cover plate is level with the
nishedgradeofthesnowmeltingsurface(seegure2).
When the socket and cover plate are level use a screw to
tightenthesocketontotherebar.(seegure3)
Failure to mount the socket properly may result in
incorrect or faulty sensor readings.
i) Ramp Mounting
The socket and cover plate can also be mounted on a
ramp. Make sure to locate the socket and cover plate near
the bottom of the ramp. This will allow for proper ice melting
whenthemeltedsnowowsdown(seegure4).
ii) Brass Plugs
On the socket there are 4 brass plugs. These plugs are
designed to make contact with the brass ring on the sensor
so the sensor can get proper slab temperatures. Take care
not to press these plugs in or out as they are properly set
at the factory. Manipulation of the plugs may result in the
sensornotttingproperlyinthesocket(seegure5).
Take special care to clean the brass surfaces on the inside
of the socket. Making sure to clean any concrete that may
have accumulated on them. Failure to do so may result in
the sensor not making proper contact and not reading the
slab temperature properly.
