Frequently Asked Questions

General Questions

  1. Q → Display does not come on.

    2. A → Check power connection at terminals 17,18,19. If no power (120VAC) present then trace power back to source. Cycle power to Control.

  2. Q → No heat demand.

    3. A → Check that you have at least 20VAC being supplied to the heat demand trigger. E.g. power to terminals 1&2 for a heat demand to follow the outdoor reset curve. Power to terminals 3&4 for a Hi temp heat demand and power to terminals 5&6 are for a DHW demand.

  3. Q → Injection not working.

    4. A → Make sure that in the mixing settings you have selected the appropriate device you are using to mix with. If it is PMIp then your connection should be attached to 26 to 28 and if it is PMIv then connect the valve to 15,16.

  4. Q → Buttons do not respond or cannot go into Programming Mode.

    5. A → Hold down buttons C and D to unlock the buttons. Hold until display says BUTTONS UNLOCKED.

  5. Q → Parameters set in control do not seem to be taking effect.

    6. A → Manually Reset Control by using a small blunt tool and gently press the reset button.

  6. Q → Boilers not staging on.

    7. A → Make sure in the boiler options that you have selected the appropriate amount of stages for the system.

  7. Q → Domestic Hot water demand not coming on.

    8. A → Make sure if you are using a Thermistor that it is hooked to terminals 9&10 on a staging control or have your aquastat attached to terminals 5&6 with power.

  8. Q → Lack of Heat or no response to a heat demand.

    9. A → Control may be in Warm Weather Shut Down mode, see "System Status" display. Is the acronym "WWSD" visible? If yes, check in "Change Designs" menu under WWSD, factory default is 75ºF. Adjust accordingly to your own design parameters. Remember to check and install your Outside temperature sensor away from direct sun or potential heat sources etc.

  9. Q → Cannot select more than 4 Boilers in Staging Options.

    10. A → If you are using the DHW control type the maximum # of boiler stages is limited to 4. Staging and Mixing control types will allow you to program up to a maximum of 14 stages but please note you must have the corresponding number of Expansion Modules to effectively accomplish this.

  10. Q → No Boiler Heat Demand when Zone Module has a call for Heat.

    11. A → Make sure you program 'Use Zone Module' to 'Y' in Control Options. Zone Modules are currently under development.

  11. Q → Can I use the HBX Controls with a BMS System?

    12. A → Yes as the outdoor sensor can take a 0-5V input.

  12. Q → Are the HBX controls BACnet or LonWorks compatible?

    13. A → Not at this time.

  13. Q → What communication protocols can your control accept?

    14. A → We have a proprietary communication protocol that we use.

  14. Q→ Will my HBX controls lose memory when unplugged it or in case of power outages?

    15. A → No. It will save the stored settings.

  15. Q→ My screen is showing garbled characters; what should I do?

    16. A → Unplug or reset the control.

  16. Q→ Why won't my lead injection pump ever shut down?

    17. A → Because in Pump setting if it is selected YES, it will not shut down.

  17. Q→ Who should I contact for pricing and inventory?

    18. A → julian@hbxcontrols.com

  18. Q → Who do I call for technical support?

    19. A → 403-720-0029 and ask for Tech Support

  19. Q→ Do your controls have remote communication capabilities; how does it work?

    20. A → Yes and we have a CIS-300 Ethernet modem that you will need to purchase that will work with our CPU/SNO/ECO-1000 controls.

  20. Q→ Can I tie in all my thermostats for muti-zone applications?

    21. A → Yes.

  21. Q→ Do I need to hook up the outdoor sensor for the Hydrobloc?

    22. A → No.

  22. Q→ Do I need to hook up my boiler sensor when using the Hydrobloc?

    23. A → Yes.

  23. Q→ Will an ECO-1000 run a chiller?

    24. A → Yes.

  24. Q → What will I need to run a snowmelt system?

    25. A →You will need a SNO-500 or 1000 control, a SNO-0110 Sensor and cable and also a SNO-0111 Snowmelt Socket and Dud Sensor.

  25. Q→ How does your optical snowmelt system work?

    26. A → The SNO-0110 snow melt sensor is unique to the hydronic industry. This sensor uses optics rather than the typical metal components to sense the presence of snow/ice. The sensor provides the SNO Control with information on snowfall intensity.

  26. Q→ What should I do if I have a defective unit?

    27. A → Contact the wholesaler or Agency that you purchased the unit from, and the warranty will be check and if it falls under the warranty, the Wholesaler/Agent will need to get an RMA number from HBX.

  27. Q→ Cannot download Designer software, what should I do?

    28. A → Call Technical Support: 403-720-0029

  28. Q→ Can I use your controls to run wood boilers?

    29. A → Yes

  29. Q→ Can I use your controls for steam boilers?

    30. A → No as a steam boiler runs hotter than 225 Deg F and our sensors can only get up to 225 Deg F.
