NovoCon® S Digital Actuator

The digital actuator NovoCon® S is tailor made to fit Danfoss AB-QM – the market leading pressure independent balancing and control valve – and establishes 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® S 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 the BMS a unique insight in, and remote access to, the HVAC system status which can be used to optimize its performance, improving the indoor comfort and achieve energy efficient buildings.

The digital actuator also offers built-in I/O's for added functionality, flexibility and cost savings. A few examples of the possibilities using the actuators’ I/O’s are:

Flow & energy indication by connecting sensors for return and supply temperature measurement with NovoCon® Energy;
Connectivity for 4-pipe changeover applications with NovoCon® CO6;
To connect different sensors (e.g. room temperature, humidity, or condensation) and control different devices such as fans with NovoCon® Remote I/O cable.

NovoCon® is an essential device in the transition to smart connected buildings with continuous monitoring, 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 offices, hotels and hospitals. But also in cruise ships, universities, data centers, shopping malls, museums or supermarkets.

NovoCon® S is applicable in various types of HVAC systems like Air Handling Units (AHU), Fan Coil Units (FCU), chilled ceilings, chilled beams, radiant panels and four-pipe changeover systems.
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.
