Description
NovoCon® S
NovoCon® S is a high accuracy multi-functional field bus actuator, specifically designed for use in combination with the Pressure Independent Control Valve type AB-QM in sizes from DN 10-32. The flow is modulated by the AB-QM pressure independent control valve to avoid overflow and reduced boiler and/or chiller efficiency.
The actuator with AB-QM is used to control water supply to fan coil units, chilled beams, induction units, small re-heaters, re-coolers, AHU’s and other terminal units for zone control, in which heating/ chilled water is the controlled medium. Due to its accuracy, remote functionality and flow indication features, this product facilitates an accelerated commissioning process, allows easy maintenance, improves indoor comfort, increases energy savings and allows for fair cost allocation of heat/cool energy.
The high position accuracy of the actuator, together with the pressure independent and linear characteristic of the AB-QM valve, allow NovoCon® S to be used as a flow indicator. Setup of the actuator and valve parameters are made via fieldbus. Control is achieved via field bus or via analog inputs to NovoCon® S.
Typical applications are:
• Radiant ceiling panels, supplied by 4 pipes (Heating supply and return and cooling supply and return).
• Fan coil units, with single coils supplied by 4 pipes (Heating supply and return and cooling supply and return).
General features:
• Remote commissioning/Pre-set/Flush features
• Flow, power emission and energy indication
• High position resolution and accuracy
• Energy management algorithms
• 4/2-pipe changeover applications
• I/O applications
• LED bar displaying status and alarms
• No tools required for mounting
• Maintenance-free lifetime
• Self-positioning process
• Low-noise operation
• Plug-in halogen free cables
• Auto MAC addressing for BACnet
• Auto baud rate detection
• Intrinsic alarm reporting for BACnet
• Valve blockage alarm
• Broken wire detection on analog control and ground signal
• Choice of BACnet MS/TP or Modbus RTU in the same product
• Mis-wiring protection on any wire up to 30 V
Combined with the Actuator NovoCon® ChangeOver6, NovoCon® S offers a unique solution in controlling both the AB-QM valve and a 6-port motorised ball valve that performs a diverting function between two water circuits in 4-pipe changeover systems.
This diverting function, primarily used for radiant panels, also allows the cooling and heating capacity of a fan coil unit to be increased for the same compact size compared to a double coil model where the heating and cooling water circuits each have their own coil.
The 6-port diverting valve and actuator work in combination with an AB-QM PIBCV valve and NovoCon® S bus actuator. The AB-QM balances the flow and the NovoCon® S bus actuator controls the flow. NovoCon® S also controls the 6-port diverting valve actuator which switches between heating and cooling. This unique functionality is characterized by the following:
• There is only one single field bus and power supply connection cable to the NovoCon® S actuator. This powers both the NovoCon® S and controls the 6-port actuator. Furthermore, there is feedback from the 6-port actuator to NovoCon® S.
• The NovoCon® S actuator automatically fault­detects, by means of comparing 0-10V control & feedback signals, if the 6-port actuator is in manual operation mode, removed from the valve or if the 6-port valve is blocked.
• The NovoCon® S actuator has two Design Flow Rate pre-settings: one for heating and another for cooling.
• The NovoCon® S actuator indicates power emission and logs energy consumption for heating and cooling energy based on flow, supply and return pipe temperature measurement.
• While in maintenance mode, the 6-port actuator is able to fully close the valve and prevent any leakage, thereby saving on stop valves.
• Logic contained within the NovoCon® S actuator, ensures that only one actuator in each pair (NovoCon® S and 6-port valve actuator) drives. This ensures that 2 actuators in the pair never drive at the same time. This reduces voltage booster demands in daisy chains.
• The NovoCon® S actuator detects if the 6-port actuator cable is disconnected. If this is the case an alarm is initiated.
Features CO6:
• NovoCon® S + ChangeOver6 actuator represents only ONE device on the fieldbus network needing no physical I/O
• No cross-flow between heating and cooling
• Simple connection and control
• Feedback for position status and alarms
• Quiet and reliable operation
• Maintenance free
• Teflon seal and polished chrome valve ball to
prevent valve sticking
• Blocked valve alarm
• Manual override

No tool is required to mount the actuator on the valve. Installation of the valve with the actuator is allowed in the horizontal position or upwards. Installation downwards is not allowed. The actuator must not be installed in an explosive atmosphere, at ambient temperature lower than 0 °C or at ambient temperature higher than 50 °C. It must not be subject to steam jets, water jets or dripping liquid.
Note: The actuator may be rotated up to 360° with respect to the valve stem by loosening the retaining fixture. Once the actuator is in place, retighten the retaining fixture.
Note: The cable and cable gland/grommet used, must not compromise the actuator’s IP rating. There must be no strain on the connectors. The rubber cable grommet delivered from factory do not compromise the IP rating but do not provide full strain relief according to the LVD directive. Please observe local rules and regulations.

Wiring
NovoCon® S
The wiring of BACnet MS/TP or Modbus RTU (RS485) must be carried out in accordance with applicable standard ANSI/TIA/EIA-485-A-1998.
Digital port
Galvanic separation shall be provided for segments crossing buildings. Common ground shall be used for all devices
Multifunctional port
on the same network inclusive router, gateways etc.
Digital port
All bus connections in the cables are made with twisted wires. The cable type used for NovoCon® analog, digital and I/O cables is AWG22/0.32mm2. If other cables are used to extend the length, always use twisted pair wire for bus signal and include ground for the bus signal. The recommended cable type is AWG22/0.32 mm2. If used for longer distances please use a AWG20/0.5mm2 or AWG18/0.75mm2 cable. The cable’s impedance characteristic shall be between 100-130Ω. The capacitance between conductors shall be less than 100 pf per meter. The length of the cables influence on the communication speed. Longer cable lengths should result in lower baud rates. The total maximum cable length allowed per network is 1200m. Use a minimum 20 cm distance between 110V/230V/400V power line cables and bus cables. NovoCon® S has mis-wiring protection on up to 30 V AC/DC on all wires, but be aware that if 30V AC are connected to the Analog input, the external power supply will see this as a short circuit and blow the fuse in the external power supply.

The important factors here are:
- Common ground
- 24VDC power supply is recommended
- In case more 24VAC power supplies are used always separate the 24VAC power supplies if different types of power supplies are used and / or different phases are used.
Wiring with DC power supply: (recommended solution)

Wiring (continued)
NovoCon® M
The wiring of BACnet MS/TP or Modbus RTU (RS485) must be carried out in accordance with applicable standard ANSI/TIA/EIA-485-A-1998. Galvanic separation shall be provided for segments crossing buildings. The bus connection ‘A+’ is the non-inverting signal and ‘B-‘ is the inverting signal wire.
Common ground shall be used for all devices on the same network including routers gateways etc. The recommended cable type is AWG22/0.32 mm2 twisted pair. If used for longer distances, please use a AWG20/0.5mm2 or AWG18/0.75 mm2 cable. The cable’s impedance characteristic shall be between 100-130 Ω. The capacitance between conductors shall be less than 100 pf per meter. The length of the cables influence the communication speed. Longer cable lengths should result in lower baud rates. The total maximum cable length allowed per network is 1200 m.
Use a minimum 20 cm separation distance between 110V/230V/400V power line cables and bus cables. NovoCon® M has mis-wiring protection up to 30V AC/DC on all wires but be aware that if 30V AC are connected to the Analog input, the external power supply will see this as a short circuit and blow the fuse in the external power supply.

Danfoss recommends that NovoCon® M should be used on its own sub-network for optimal performance.
General requirements and recommendations:
• Use the termination resistor (between the 2 connectors) at the end of each daisy chain.
• Generally, one power supply is preferred.
• If two power supplies are used, they must have the same polarity and the same common ground.
• A common ground must be used for all devices on the same sub-network, including routers and gateways.
• Galvanic separation shall be provided for segments crossing buildings.
• Total maximum sub-network cable length is 1200m.

T-junctions
T-junction connections (stub lines) are not recommended. In the event of T-Junction connections being used the following limitations must be adhered to:
- max T-junction cable length 1.5m (shortest standard digital cable)
- total length of Network max 640m (+ 100m stub length)
- max baud rate 76 kb/s 1)
- max number of devices on network 64 1)
- main cable should be standard RS485 bus, twisted pair, min thickness AWG22 / 0.32mm2.

When using less than 32 devices you may attempt to raise the speed to 115 kb/s.
Star topology
Star topology is not according to the RS485 standard and should not be used with NovoCon® S, M and L/XL.
DC Power supply (recommended)
When daisy chaining with 10m NovoCon® cables and using a 24V DC power supply, additional voltage boosters/power supply is needed when 12 NovoCons in series is exceeded. See table below.
AC Power supply When daisy chaining with 10m NovoCon® cables and using a 24V AC power supply, additional voltage boosters/power supply is needed when 7 NovoCons in series is exceeded. See table below. Important: The power supply used must be able to deliver 60% more power than the nominal rating of NovoCon® S.

If the supply voltage to the first device in the daisy chain is lower than 24V AC/DC, or long thin cables other than NovoCon® cables are used, then the quantity of devices in the daisy chain may have to be reduced.
The recommended maximum quantities of NovoCon® S are 64 pcs in one daisy chain connection. If other BACnet devices are added with NovoCon® S in the same daisy chain connection, Danfoss recommends a maximum of 32 pcs. to ensure sufficient network speed.
Danfoss recommends that NovoCon® S should be used on its own sub-network for optimal performance.
General requirements and recommendations:
• Use Danfoss daisy chain cable to connect two NovoCon® S devices.
• Use Danfoss digital cable to connect NovoCon® S with another BACnet device.
• The current in cables should not exceed 3Arms at 30°C.
• Use the termination resistor (DIP switch 8) at the end of daisy chain.
• Voltage boosting may be achieved via any port.
• Generally, one power supply is preferred.
• If two power supplies are used, they must have the same polarity and the same common ground.
• A common ground must be used for all devices on the same sub-network, including routers and gateways.
• Galvanic separation shall be provided for segments crossing buildings.
• Total maximum sub-network cable length is 1200m.
