Introduction
Danfoss Digital Hydronics™ offers you a highly flexible, modular solution for hydronic HVAC 4.0 designs. The digitalization of HVAC
systems opens a world of possibilities to increase energy efficiency and user comfort to new levels. To achieve this, it is highly important
to establish a dynamic hydronic balance throughout the building. BMS connected digital actuators not only provide highly accurate
temperature control, but their data inputs are also essential. Optional temperature and flow data expand the insights and allow
continuous energy optimization. Danfoss Digital Hydronics™ covers all what is needed to establish a fully digital hydronic HVAC system.
In this factsheet we describe how the different components in the solution are best combined. This is split into different application
needs, based on required design flows.
For e.g. Terminal units up to DN 32, the combination consists of AB-QM (4.0) + NovoCon S +SonoSensor 30
For e.g. Air Handling Units up to DN 100, the combination exists of AB-QM + NovoCon M +SonoSensor 30
For e.g. Chillers and District cooling up to DN 250, the combination exists of AB- QM + NovoCon L/XL + SONO 3500 CT

The sensor unit consists of a platinum
element, the resistance value of wich, changes
proportionally with the temperature.
Pt 1000 ohm sensor (1000 ohm at 0°C).
The sensor is adjusted and meets the tolerance
requirements of EN 60751 Class B.
The accuracy of temperature measurement is
approximately 0.5° in typical operating range.
It is unlikely, that during calculation of ∆T,
deviation of both sensors would be summed up.
Therefore, it is estimated that ∆T measurement
accuracy is 0.5° when the sensors are mounted
correctly.
It is not recommended to use longer wires on
temperature sensors than 2m due to risk of
electromagnetic interference. If long or thin wires
are used it may be necessary to make an offset of
the temperature reading in the BMS system.
SonoSensor 30 is an ultrasonic flow sensor
especially designed for heating, cooling or
combined heating/cooling application in local
and district energy systems. It can be used in
conjunction with the type approved heating/
cooling energy calculator (e.g. Infocal 9) to form
combined heating/cooling energy meter.
SonoSensor 30 has been approved according to
MID in accuracy class 2. The flow sensor can be
mounted in both flow and return pipe.

NovoCon® S supports connection of flow sensor directly to NovoCon® IO cable. Flow sensor must be
connected to AI and AO terminal. NovoCon must be set to digital mode (MSV:9/32810 = 2), output
functionality set to Inactive (BV:3/32817 = 0) and value of output (AO:0/33286 = 10) on 10 V. You also
need to select AI (MSV: 41/32821) input for connecting flow sensor.
To get right flow sensor value it is verry important to set right value of liters per pulse on NovoCon®
(AV: 43/32864). Usually this is written on flow sensor specification sheet. If we would like to use flow
sensor for calculating energy we must also change register MSV12/32814*.
