The SNO-1000 and SNO-0100 have gone through
rigorous quality control tests at the factory before
shipment. After receipt and before installation perform
the following checks:
Inspection
After unpacking the unit make sure the boxes contain:
SNO-1000 Package:
• SNO-1000 Snowmelt Control
• 1 Terminal Screwdriver (3.0mm)
• 3 Cable Ties
• 1 Remote Outdoor Temperature Sensor

where the relative humidity is less than 95%
• Do not store in places where the unit may come
into contact with corrosive gases or liquids
• Do not store in an area or upon an unstable
surface where it may become damaged due to
falling
GETTING STARTED
This manual will help with the installation, parameter
setting, troubleshooting and general maintenance
requirements for the control, and the module. To
guarantee the safe and reliable operation of your
snowmelt system, you must rst read this manual
in detail and take particular note of any and all
warnings or caution directives prior to connecting
to AC power.
Only suitably qualied individuals with
formal training in electrical and HVAC

PlacetheSNO-1000anddesiredSNO-0100onaat
surface. Align the 32-Pin connector with the holes
on the module and gently push into place. Next
slide the SNO-1000 onto the 32-Pin connection by
carefully matching up the holes and pins. When
installed correctly there is virtually no gap between
the units. With power applied to the assembly,
the rst (green) LED should be illuminated on the
module. This lit, green LED serves as conrmation

3. Menu and Programming Buttons:
These buttons will be used to set up the Control
during commissioning and for toggling between
displays or troubleshooting at a later date if
necessary.
4. Serial Number and Bar Code:
This label will identify the entire factory ordered
options and the date of manufacture. It can also
be used for re-ordering and will be required in the
event of factory service assistance or warranty
claim.
5. Communication Connection:
The standard communications port (RS-232) is
found directly below the bar code label. Optional
communications software needs to be purchased
to enable a connection. Please consult factory or
dealer.
Only a CAB-0100 can be inserted into this
connection without causing damage.
Example:
Viewing from top left and moving right in a
clockwise direction:
1. Back-Lit Graphic Display:
The display is one of the key features of the
Control. Depending upon which mode of
operation is selected, you will be able to view
most common system values simultaneously. It
will also serve as a visual indicator when in the
programming mode.
2. Lockable Keypad Option:
Once your system has been programmed and
optimized there should be little or no reason for
further changes. The Control has been designed
with the ability to physically “hard-lock” the
keypad to prevent tampering with the settings.
Refer to pg 11 for “hard lock” instructions.

11. Backup Battery:
The lithium-ion battery is purely a back-up supply
for the real time clock and will keep the clock
refreshed during a power interruption to the
Control.
Prior to installation, please remove the
protective paper strip to activate the
back-up battery as shown below.
6. 120 VAC Pump Outputs:
There are three separate (3-wire) 120VAC output
power terminals designed to run either a pump or
fan.
7. 120 VAC Power Input:
There is one (3-wire) terminal block for incoming
120VAC power.
8. Boiler Relays:
These are used to run boilers. The SNO-1000 can
run up to 2 On/Off Boilers by itself.
9. Thermistor/Sensor Inputs:
There are three (2-wire) sensor/thermistor inputs.
Under no circumstance should power be
applied to these terminals! Permanent
damage to the Control’s circuitry may
result.
10. Demand Inputs:
There are three (2-wire) “demand” control inputs.
Control signals between 20-240VAC are designed
1. 32 Pin Connector Port
The 32-Pin Connector Port allows a 32 pin

INSTALLATION & WIRING
The SNO-1000 and SNO-0100 are designed to be wall mounted, DIN rail mounted, or installed inside a separate
electrical enclosure. The unit should be mounted inside and be protected from falling water and high humidity
conditions. With all the covers in place it is designed to protect any individual from accidental electrical shock.
The Control has a built in 5Amp fast acting fuse to protect the circuitry on the Printed Circuit Board (PCB). The
unit is designed to power up to 3 pumps and 2 auxiliary relays of 10Amps each. As such, an upstream customer
supplied fuse or circuit breaker rated at a maximum of 30 amps must be in circuit. It is the installers responsibility
to provide either a 3 pin (3ft max) grounded plug and cable, or the unit must be wired directly to a breaker and
terminated inside the control box (terminals 17, 18 & 19).
All power wiring must be with a minimum of 18AWG wire.
Low power wiring ----------- insulated 18AWG (min.) wire to a max of 500ft.
Thermistor wiring ------------ insulated 18AWG (min.) wire to a max of 500ft.
It is recommended to use 18AWG Single Stranded Wire. It is also recommended to run signal and
power wiring in separate conduit.
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.

HBX Snowmelt System
Version 1.08
Page 9
P2 Relay - Any pump (or fan) output rated to
a max of 10Amps 120VAC. This relay is pre-
programmed to be the default (low temp) system
pump. When programmed for a mixing system.
P1 Relay - Any pump (or fan) output rated to
a max of 10Amps 120VAC. This relay is pre-
programmed to be the default boiler or (High
Temp) system pump.
Supply Power - The 3-wire 120VAC input to the
control. Protected by a 30Amp breaker or fuse.
Relay 2 - This relay is the default relay for bringing
on the 2nd Boiler or Boiler stage. It can be used as
an injection valve.
Relay 1 - This relay is the default relay for bringing
on the 1st Boiler or Boiler stage.
Misc Relays 1&2 are Dry Contacts and
rated for a max of 10Amps
Snowmelt Demand - This demand is used for the
main Snowmelt demand. This will put the control in
idle mode when no snow is present.
Forced Melt Demand - This demand will force the
control into melt mode. It will only stay in melt
mode for a predetermined amount of time. To use
again the user must take the demand away and
then reapply.
Zone Demand - This demand is used to tell the
control to only watch the extra slab zone. When
engaged the control will run the zone slab like a
setpoint.
Thermistor 1 - Boiler Sensor
Thermistor 2 - System Sensor
Thermistor 3 - Outdoor Sensor
TM1, TM2 & TM3 are designed for 10K Ohm
Thermistors and must never be subjected
to any external power supply (voltage or
current)
P3 Relay - Any pump (or fan) output rated to
a max of 10Amps 120VAC. This relay is pre-
programmed to be the default injection pump
relay when PMIp is the injection mixing strategy.

Snowmelt Sensor - This is where you attach the
Snowmelt Sensor.
Take care not to mix up the wiring.
Thermistors - These are the inputs for the return
sensor and the second (only) slab zone sensor.
Modulating Output - This modulating output can
be used for a modulating boiler, modulating
valve, or it can run a VFD for a pump. This is a
4-20mA or 1-10v Signal.
Supply Power 120VAC - The 3-wire 120VAC input
to the control. Protected by a 30Amp breaker or
fuse.
Relay Outputs
These relay outputs are only used for a oating
action (power open / power close) valve or this is
the output for the slab (only) zone pump/valve.
Dipswitch
The SNO-0100 is able to output either a 4-20mA
signal or a 1-10VDC signal from contacts 8 and 9
using a modulating output.
For 4-20mA the dipswitch is set to OFF (up
position).
For 1-10VDC the dipswitch is set to ON (down
position).
