NV LOGIQ Room Controller

The NV LogiQ Room Controller has been designed to offer an effective, efficient and user friendly solution for adaptive natural ventilation applications that are easily integrated into new or refurbished buildings.

The NV LogiQ Room Controller can be used as a stand alone system or networked to give individual room control with global common signals such as wind, rain and security closing.

All this within a small wall mounted enclosure, the NV LogiQ Room Controller has integrated sensors, switches and a backlit LCD display that offers many facilities without the need for separate sensors within the room.

There is a pre-programmed natural ventilation control algorithm that has been developed in partnership between SE Controls and Loughborough University’s Building Energy Research Group. This strategy was formulated by modelling hundreds of scenarios and in conjunction with industry recognised methods and data collected from natural ventilation projects installed over several years by SE Controls.

Specification: The system comprises a number of automatically opening natural and/or smoke ventilators.  The purpose of these ventilators is to provide smoke ventilation and  day to day thermal comfort ventilation under the control of the local occupant and automated cooling for the building.

Zone controllers are to be SE CONTROLS OS2 microprocessor based system and provide networking capability to implement complicate controls from Automatic Fire Detection System (AFA). The OS2 zone controller operates the smoke vent actuators dependent on the type of inputs, fully open or close in case of fire mode and in proportional mode for day to day comfort control. To maintain system performance & compatibility, all equipment will be provided, installed, commissioned and maintained by Unique Window Services 07 32655771.

Smoke Vent Actuators

Each Smoke Vent  will be operated by either one,  two or multiple actuators. (if more than one actuator is used on a vent,  they must be operated under synchronized mode).  The type of actuator will be determined by the performance requirements of the ventilator and will take into account weather performance, size and weight, number of operations and other requirements.  The actuators are to  be 24vDC and operate on 2 wires system with a power open, power close basis with proportional opening achieved by an compatible zone controller  supply  to the actuator.  Switching of the actuators will be by reversing the polarity of the supply to the actuators.

Each actuator will be protected by end switches or electronic limits switches. Operating temperature should be -5 to 75 degree Celsius, humidity 10 – 95% non condensing.

7. The actuator shall be tested to meet elevated temperature test at 300 degree C as per EN 12101-2 Annex G.

8. In cases where there are more than one actuator used on a smoke vent, an electronic synchronizing devices with a microprocessor control should be used to support wide and heavy windows. (no current sensing tandem switch is allowed to use for protection).

9. The force of the actuator shall be minimum 400N both for retract and push force.

10. The clamping force of the actuator should be more than 4,000N.

Power Input/Output Requirements

Each Window Controller requires a 230vAC fused input.  The Window Controller contains a 230v – 24vDC transformer rectifier unit with an output of 8 to 10 amps at 24vDC.  The Window Controller also contains battery backup, of sufficient capacity to provide safety operations in a mains power fail situation.

Output Switching Operation

Reverse polarity to open and close window actuator via 2 wire output.

Battery Backup (applicable to smoke ventilation only).

In-built facility to contain battery backup of sufficient capacity to provide 8 hrs     emergency operation of the window actuator(s) in the case of mains power failure. The battery backup will be fully monitored such that at a predetermined level, a fault indication can be signaled remotely via the window controller network.

When mains power is disconnected, the day to day switch is disable to conserve battery power.

Output Signals

The local window controller shall be capable of giving external signals to indicate activated, fault and status signals. These outputs shall be via LonWorks or Volt free contacts.LonWorks or Volt free contacts.

Input Signals

The local window controller shall be capable of receiving a local input from a rocker switch, with the purpose of opening and closing the local window actuator. The local window controller shall be capable of fully opening and fully closing the window actuator via a single pulsed operation of the rocker switch OR can be re-programmed to allow proportional opening and closing of the window actuator. Proportional control will enable the window actuator to operate when the rocker switch is depressed and stop when the rocker switch is released.

The local window controller shall be capable of receiving input(s) from other local window controllers, other local devices and/or the Building Management System. These inputs may take the form of digital inputs, volt free inputs, analogue inputs (0-10V dc) and Lonworks.

Each Window Controller can also receive a 0-10vDC input signal, and can be programmed for specific functional requirements.  eg. or other combination of strategy

How many times have you been at work, heard a storm warning and said but I have the washing on the line and my windows are open!!!!! There is not much we can do to help with the washing but the windows are a different story.

Installing a rain sensor with your electric window controls will give you some peace of mind when the storms come rolling in. Whether it is your home, your school or your office the functionality of this device could save you a costly cleaning bill or messy insurance claim.

Placed on the roof, the rain sensor will send a ‘close’ command to the controlled windows at the first drops of rain. This signal will continue until the sensor pad is dry again.  Once the signal has ceased the occupants will again have full control of the windows and can open them at their leisure.

To ensure this happens in a timely manner there is a small ‘heater’ in the sensor. This works to evaporate the water as soon as possible halting the ‘close’ command.

Feel free to call us and discuss this option as it does add a very useful element to any automated window system.

Specification: The automated window control system is to be interfaced with a Rain Sensor located externally on the building in a position that will not be impeded from rain.

The sensor is to be a Dual PCB type available from Unique Window Services 07 32655771.


Our RF unit is a great way to control any number of windows. With recently developed wiring options the opportunities are endless.

For instance, should you have clerestory windows on all four sides of your room you can control each side with the remote. Meaning that during a storm you can still have at least one or two banks open and never have to leave the couch! Alternatively, should you have windows in various areas of your property and these are in different rooms, all the windows can be controlled from one point making opening and closing a very easy task. Each bank can be controlled independently of the others or they can be controlled as a whole.

The RF units are also a great option for retro fitting electric controls to existing properties. With minimal wiring required compared to the wall mounted system a nice clean result is achieved. The receiver is a small box and can be mounted almost anywhere that is convenient for the end occupant and the hand held remote can be wall mounted or easily accommodated in the draw of a coffee table or hall stand. Both have clean lines and are designed to be unobtrusive.

Specification: The window automation system is to be interfaced with a Radio Frequency hand held remote control system. Transmitter is to have the capability of controlling 1 zone at a time and up to 5 zones simultaneously.

The system is available from Unique Window Services, (07) 3265-5771.
