DESCRIPTION The SNO-0550 is a stand-alone snowmelt control that utilizes a unique sensor technology unmatched by any other snowmelt control system on the market today. This control utilizes proprietary sensor technology to detect falling snow. The snowmelt sensor uses a heater to melt the snow that lands on the sensor. The control then measures actual snow fall rate.

The SNO-0550 consists of numerous exceptional features including settings for your snow fall intensity as well as an adjustable ΔT. This distinctive design incorporates our user friendly programming features, while offering applications and snow melt provisions over and above conventional slab sensing. With the ability to control a system and an injection pump, or a floating action valve for mixing purposes, this value added stand-alone control is suitable for single scale projects, or multi-zone projects that require individual optical sensors for each melt zone.

The SNO-0550 can also be controlled remotely using your smartphone or tablet device with the free HBX ThermoLinx App. The ThermoLinx App allows you to control your snow melt system with the ability to set snow fall rates, adjust/monitor targets, set slab demands , and the ability to turn on/off your snow melt system anytime, anywhere.

Some features of the HBX SNO-0550 are:

• Pre-set snow conditions - Very Light - Light - Moderate - Heavy • Utilizes optical snow fall settings technology • Integrated slab sensor (can be installed remotely) • Injection and mixing valve control • System pump control • Warm / Cold weather shutdown • Smart testing function • Wi-Fi Enabled • Remotely access via Apple® and Android™ smartphone or tablet devices

As seen here, based on a “Light” snowfall setting, you

can see the HBX sensor will turn on the snowmelt system Heay much later than a conventional sensor. This results in huge savings each snow season if your system can turn on later and turn off sooner. Moderate

SENSOR ERRORS

HTR-LOWC: Low current is being drawn into the sensor and will not sense snow. Check the wiring of the control. Refer to testing procedure on page 23, and inspect the SNO-0110 Sensor for signs of damage or improper drainage.

Reset control when issue has been corrected to eliminate error code.

HTR-FAULT: High current is being drawn into the sensor and will not sense snow. Screen will flash orange, and fuse in control will trip. Check the wiring of the control. Refer to testing procedure on page 23, and inspect the SNO-0110 Sensor for signs of damage or improper drainage.

Reset control when issue has been corrected to eliminate error code.

ON: Control is awaiting signal from optical sensor or Forced Melt Demand from user.

OFF: Control is in WWSD/CWSD or no demand is present (Pins 6-7) when in DEMAND mode STANDBY/IDLE (See Page 11)

MELT: Control is ON and snow was detected by the sensor higher then the intensity setting.

IDLE: Control is ON and maintaining the slab at the idle temperature until snow is detected by optical sensor or forced melt demand is given by user.

STANDBY: Control is ON but not maintaining a slab temperature. Control will remain ON until snow is detected by optical sensor or forced melt demand is given by user.

ANTICIPATE: Control will be ON in STANDBY or IDLE for the amount of time determined by the user in ANTICIPATE DAYS.

ANTICIPATE DAYS: If snow is detected during this time control will go in to melt mode. Otherwise the control will be OFF after ANTICIPATE DAYS has elapsed.

FORCE MELT: When control is ON and awaiting snow detection by optical sensor, if demand is given (PINS 6-7) control will go into melt mode. Pressing UP and DOWN arrow buttons simultaneously for approximatelty 10 seconds will also override sensor and force melt mode.

1. Demand Type This setting is used to determine what the slab does when a demand is given to the control:

Force Melt: When a demand is given the control will go into MELT Mode. When no demand is given, the optical sensor will actively look for snow to trigger a melt demand.

Standby/Idle: When a demand is given, the control will turn on and await snow detection by the optical sensor or Force Melt demand by user. When no manual demand is present, control will be in an OFF state.

Anticipate: When a demand is give the control will turn ON for the amount of time (1-7 days) selected in Aniticpate days (Advanced Settings) and await snow detection by optical sensor or Force Melt Demand by the user.

2. Demand This allows you to toggle the demand On/Off.

3. Melt Now/Off This allows you to turn Melt Mode off.

4. Advanced Settings Allows you to have access to all the settings on the SNO-0550 control including snow rate setup, Design temperatures, Slab and System setup.

A contractor code is required for Advanced Settings. Contact HBX Technical Support for this code.

ISSUE POSSIBLE CAUSES & RESOLUTIONS

Cracked sensor • Improper drainage (see pg. 6 SNO-0110 manual. ) • Improper Installation – too much tension on screw tightening, hammering sensor into socket. • Resolution: Replace Sensor

Not melting any snow • Sensors not connected (supply, return, outdoor) • Damaged sensor: check sensor for cracks or deformations • Incorrect settings: Idle temperature is set incorrect, Melt temp is set incorrect, melt time is set incorrect, one or more design temperatures set incorrect. (refer to page 10.) • Demand type: set to Standby/Idle or no demand is present • Doesn’t read slab temperature (sensor) • Improper wiring (see page 20.) • Sensor location in slab setup is set incorrectly. (See page 10.) • Improper sensor physical location

Residual snow is present after • Max temperature is too low and WWSD is set too high demand is not present • Melt time is set too low. Resolution: Increase time.

Slab temperature Error • Incorrect wiring (Shield wire not connected) (See page 20. ) • Heater has not reached operating temperature. Wait for at least 1 hour after installation. • Sensor location in slab setup is set incorrectly. (See page 10.) • Damaged sensor: check for cracks or deformations

Doesn’t detect snow • Damaged sensor: check for cracks or deformations • Improper wiring. See page 19 or see SNO-0110 troubleshooting section in manual. • Sensor location in slab setup is set incorrectly. (See page 10.) • Snow rate setup is set too high. (See page 8.) • No demand is present. (See page 11.) • WWSD is set too low. (See page 9.) • CWSD is set too high. (See page 9.)

Display Screen is Involuntary • Display button is stuck Switching

Display Screen is Flickering • Up/down/enter button is stuck

Control does not power up • Check power supply (120V) • Damaged PCB. Resolution: contact HBX Technical Support.

ISSUE POSSIBLE CAUSES & RESOLUTIONS

Error showing on screen • Sensor is not installed. See wiring on page 19. • Damaged Sensor: check for cracks or deformations (Slab temperature) • Slab setup is incorrect. (See page 10.)

Injection pump not turning on • Check wiring. (See page 20) • Make sure mixing is set to injection. (See page 11.)

Build-up of snow to start melting • Slab Snow rate setup is too high • Delta T is set too low. (See page 8.)

Valve not turning on • Mixing setup needs to be set to floating.(See page 11.) • Check the wiring (see page 20.)

Snow melt is on when no snow is • Damaged sensor: check for cracks or deformations present • Check SNO-0110 troubleshooting manual

Not automatically turning on • No demand present. (See page 11.) • Demand is set to Standby/Idle or Anticipate. (See page 11.)

Force Demand Melt Mode not • Demand is not in Force Demand Melt. (See page 11.) working

System Pump Not Working • Check Wiring (see page 20.)

Boiler is not working • Check wiring: (See page 20.) • Check system design temperatures. (See page 9.)

Slab Temp changes drastically • The optical sensor has a built in heater and when it is installed when it comes in or out of WWSD/ in the slab. without the Aux. slab sensor the control will minus off CWSD approximately 40F/22C off the actual slab temp to accommodate for the internal heater that has now started up. This heater can take up to 1 hour to reach it’s setpoint, thus your slab will appear that it is much colder when it first turns on, the opposite is true when it goes into WWSD or CWSD the slab temp will jump by 40F/22C as the control removes the adjustment, and the heater will now slowly cool down which could take up to 1 hour.

Any package/s returned to HBX without an approved and visible RMA number will be rejected and shipped back to purchaser at purchaser’s expense. HBX reserves the right, if deemed necessary, to charge a reasonable levy for costs incurred, additional to mailing or shipping costs.

Limitation of Warranties If the HBX product does not operate as warranted above the purchasers sole remedy shall be, at HBX’s option, repair or replacement. The foregoing warranties and remedies are exclusive and in lieu of all other warranties, expressed or implied, either in fact or by operation of law, statutory or otherwise, including warranties of merchantability and fitness for a particular purpose/application. HBX neither assumes nor authorizes any other person to assume for it any other liability in connection with the sale, installation maintenance or use of HBX Controls products. HBX shall not be liable under this warranty; if its testing and examination discloses that the alleged defect in the product does not exist or was caused by the purchasers or third persons misuse, neglect, improper installation or testing, unauthorized attempts to repair or any other cause beyond the range of intended use, or by accident, fire, lightning or other hazard.

Limitation of Liability In no event will HBX be liable for any damages, including loss of data, loss of profits, costs of cover or other incidental, consequential or indirect damages arising out of the installation, maintenance, commissioning, performance, failure or interruption of an HBX product, however caused and on any theory of liability. This limitation will apply even if HBX has been advised of the possibility of such damage.

Local Law This limited warranty statement gives the purchaser specific legal rights. The purchaser may also have other rights which vary from state to state in the United States, from Province to Province in Canada and from Country to Country elsewhere in the world. To the extent this Limited Warranty Statement is inconsistent with local law, this statement shall be deemed modified to be consistent with such local law. Under such local law, certain disclaimers and limitations of this statement may not apply to the purchaser. For example, some states in the United States, as well as some governments outside the United States (including Canadian Provinces), may: Preclude the disclaimers and limitations in this statement from limiting the statutory rights of a consumer (e.g. United Kingdom); Otherwise restrict the ability of a manufacturer to enforce such disclaimers or limitations; or Grant the purchaser additional warranty rights which the manufacturer cannot disclaim, or not allow limitations on the duration of implied warranties.
