| How it works

Overview

The hardware HelioNode on the software side supports various profiles to provide enhanced control of equipment that is controlled and monitored by the 75F solution,  for both modulating and multi-staged equipment.

It is a part of 75F's vertically integrated suite of intelligent building solutions, delivering multi-mode sensing, remote monitoring , and individual zone control for the comfort and productivity of building occupants. 

It is a replacement for SmartNode, it has all the features the SmartNode had, and additionally, it also has inbuilt light, occupancy, temperature-humidity, and CO2 sensors.  

HelioNode is an advanced IoT room controller created for temperature, IAQ, and lighting control in office buildings. It eliminates wiring runs or additional integration of sensors. Its low-profile blends with most office environments and its versatile design allow it to be mounted on junction boxes, hard ceilings, or ceiling tiles.

It works seamlessly 'out of the box with the Facilisight suite of applications, with thoughtful design touches which include, large cut-outs making it easy to install when wearing gloves, knurled edges for easy grip, a ring close design that is easy to lock/unlock when up on a ladder, a size that is easy to hold and finger holds behind the base plate to support the unit when pressing the buttons. The HelioNode dramatically cuts down the time to install and commission applications such as  

  • Dynamic Airflow Balancing (DAB) using Smart Dampers/ external actuators  
  • Variable Air Volume (VAV) based on ASHRAE GPC-36  
  • Advanced sequences for occupancy-based demand control ventilation (IAQ) compatible with ASHRAE 90.1 and ASHRAE 62.1 2018.  

Operation

HelioNode is powered by commonly run 24V ac or dc, using it you can control 2 Smart Dampers, or provide 2 0-10V analogs out signals for external actuators or lights. With 2 relays you can provide additional versatility in terms of switching loads on or off. In addition, with a full RS 485 port with power and a low voltage sensor bus, you can extend its applications.  

| Configuration

HelioNode is integrated into existing CCUs and is available as a pairable option on the floor planner.

Below is a procedure to pair and configure a HelioNode profile.

From the Select Device type screen

  • Select SN Smart Node |HN Helio Node.

The Smart Node |Helio Node Select module Type screen is displayed with the following system profile options available for selection.

  • VAV with Reheat
  • Dynamic Airflow Balancing
  • Singel Stage Equipment
  • Pi Loop Controller
  • Energy Meter

Based on the system profile the CCU is controlling the terminal profiles for the HelioNode differs

For a Default System Profile, the HelioNode can support the following terminal profiles.
