HLS34 Networkable Modbus Room Controllers- Next Generation Fan Coil Unit Control
SyxthSense HLS34
Modbus Intelligent Room Controller are designed for wide range of applications
including 2-pipe and 4-pipe fan coil unit control with built-in
fan speed control logic.
The key features of the HLS34 are:-
- Intelligent Room Controller with Accurate Display
- Touchsensitive “Magic Buttons” for Settings
- 0..10Vdc, Thermic or 24Vac Raise/Lower Actuator Support
- Simple Configuration through on-board Display
- Modbus RS-485 Networking Capability with Well Defined Specification – use with any BMS
- CO2 Demand Based Control Logic as Standard
- Built-in Temperature Sensor with Remote NTC10 Sensor Option
- Fast Large Site Configuration via “Connect & Set” Master Module saves valuable commissioning time
- Design, Quality and Value in a single solution
HLS34 is not just any fan coil unit controller, it has features and functionality that far exceed the controllers typically found in the market. Its Modbus networking capabilities and smart modular structure make it an attractive proposition to any building that requires excellent control.
Not only that, the product has also been designed with installation and commissioning in mind; it is extremely easy to set up and wire saving valuable time, offering true no hassle solution.
The new Part F & L Building Regulations come into effect asking for demand based ventilation. How can this be done with standard fan coil unit controllers? HLS34 is already a step ahead as it has built-in CO2 demand based ventilation program for controlling the fan speed.
- Modbus HLS34 Fan Coil Unit Controllers with Display
- Unique for both Temperature and CO2 Demand Based Control
- Utilises “Magic Buttons” Touch Technology
- Use with any BMS or with Netbiter Web-Browser Interface
0..10Vdc, 24V 3-Point and PWM Actuator Support as Standard
The controller can be used with any type of actuator. Multiple outputs offer flexibility to any heating or cooling application.
Fan speed control is either fully modulating 0..10Vdc or 230Vac relay control via FCRY-3 fan speed control module.
Networking Capabilities of HLS34
HLS34 controllers use industry standard Modbus RS-485 communication. The products have been designed with standard messaging formats making them ideal for use with most BMS solutions such as Trend, Satchwell and TAC, Tridium, Honeywell, Priva, York and so on..
Comparison Between HLS34 and Standard Fan Coil Unit Controllers
| FEATURE | HLS34-S1 | HLS34-S2 | STANDARD FCU CONTROLLER |
| Temperature Control via Thermic Actuators | YES | YES | YES |
| Temperature control via accurate 3-Point / 0..10Vdc | YES | YES | NO (high end models only) |
| Graphical LCD Screen and User Adjustment Buttons | YES | YES | NO (typically display an option) |
| Local Hardware Mode Override (PIR) | YES | YES | YES (in most models) |
| Industry Standard Networking | YES | YES | Depends on the model |
| Automatic Reset of User Setpoint Adjustment (Energy Saving Feature) | YES | YES | NO (often possible to engineer at front-end but not implemented) |
| Integral Demand Based Air Quality (CO2) Control | YES | YES | NO |
| Plug & Connect Master Configuration Tool | YES | YES | Often time consuming to configure individual controllers as a part of network |
BMS System Capabilities using SyxthSense Controls
HLS34 can be used with WebBiter embedded web-server allowing users to interrogate the devices and change the settings via a web-browser. WebBiter offers remote connectivity via Internet, a dial-up modem, a GPRS/GSM modem or G3 internet router. Alarms can be transmitted as text messages to mobile phones or emailed as and when required. Built-in data logging capability and standard data storage methods offer flexible system monitoring. WebBiter devices can also be connected to the netbiter.net central hosting platform.
