NovoCon® Digital Controls

Connectivity and data integration for an optimized hydronic system...

NovoCon® digital actuators are tailor made to fit Danfoss AB-QM™ Pressure Independent Balancing Control Valves. They establish the perfect connection between superior hydronic HVAC system performance and smart building automation solutions.

Traditional controlled actuators, at best, offer an analog feedback signal to the BMS room controller. Instead, the NovoCon^® actuators offers many digital system parameters directly to the Building Management System via BACnet or Modbus. It for example exchanges accurate information about the actuator/valve position, settings, temperatures, alarms etc.

All the information provides System Integrators and facility managers with unique insight and remote access to the HVAC system. The actual HVAC data can be used to optimize the systems performance, improving the indoor comfort and an energy efficient building.

NovoCon® digital control actuators enable continuous monitoring, active energy management and preventive maintenance at the highest comfort level and lowest operating costs. The digital actuators can be used in many building types such as universities, hospitals, offices, and hotels.

NovoCon® series:

NovoCon® S fits AB-QM valves ½" to 1¼" (DN 10-32). Typical applications include Terminal Units such as Fan Coil Units (FCU), chilled beams and radiant panels. The valves are used in two-pipe heating or cooling and four-pipe heating/cooling change-over systems for maximum flows from 1.2 to 17.5 GPM. For fast and reliable installation, we recommend the NovoCon® S only be connected to the BMS and wired in daisy-chain using our series of connection cables.
NovoCon® M fits AB-QM valves 1½" to 2" (DN 40-100). These combinations are applicable for the control of higher volume maximum flows from 33 to 55 GPM in e.g. Air Handling Units (AHU).
NovoCon® L fits AB-QM™ valves 5" to 6" (DN 125-150). These combinations control high volume flows from 395 to 830 GPM in e.g. chiller applications.
NovoCon® XL fits AB-QM™ valves 8" to 10"(DN 200-250). These larger combinations are applicable for control of the highest volume maximum flows from 830 to 1600 GPM in e.g. District cooling applications.

Built-in I/O

The digital actuators also offers built-in I/O's for added functionality, flexibility and cost savings. In some applications this can replace I/O modules from the BMS. A few examples of using the actuators’ I/O’s are:

Flow & energy indication by connecting sensors for return and supply temperature measurement with NovoCon® Energy
To connect different sensors (e.g. room temperature, humidity, or condensation) and control different devices such as fans with NovoCon® Remote I/O cable

Remote commissioning of ABQM pressure independent valves with NovoCon® digital controls

View the AB-QM™ and NovoCon® digital controls in a HVAC system. The valve absorbs pressure fluctuations and maintains the designed flow. With NovoCon®, the designed flow can be remotely re-commissioned, commissioning up to 64 valves at the same time.

Engineering hydronic efficiency with NovoCon® digital controls & AB-QM™ pressure independent balancing control valves (PIBCVs)

See how traditional control valves perform in a buildings hydronic system and learn how AB-QM™ pressure independent balancing control valves (PIBCVs or PICVs) with NovoCon® digital controls can be an efficient alternative to achieve hydronic system optimization at either full or partial load conditions.

Features and benefits

Remote access

Via the BMS system and bus communication all actuators can be remotely accessed. This saves a lot of time during the installation and commissioning of the system as well as during the many years the building is operational.
Continuous commissioning

System data can be retrieved and analyzed in order to optimize the HVAC system. In case adaptions to e.g. setting of design flows are required, it can easy be done. On one, a few or all actuators at the same time. Continuously monitoring and commissioning the system saves time and costs throughout the life cycle of the building.
Predictive maintenance

Don't wait for HVAC components to fail, cause complaints and need for urgent and disturbing service activities. Instead you can see where and when an issue might occur and you can take precautions and act pro-actively.
Flexibility all over

The designers or system integrators of BMS systems can realize customized HVAC solutions for every project. In case the building user wants to refurbish the building, the HVAC system can be adapted accordingly without physical adjustments to the BMS components.
