Introduction
The NVLogiQ PSU is an adaptive Environmental Ventilation single zone
control panel and can be networked in multi zone projects.
It has the ability to operate on its own through manual switches, or it
can be connected to the BMS to manage the AOVs as required.
The NVLogiQ PSU can be installed into new and refurbished buildings
where there is a focus on indoor air quality and energy saving.
The physical size and appearance has been purposely designed to
enable surface mounting for new and refurbishment projects.

NV LogIQ Power Supply
Technical Information & Operating Instructions
Application
The NV LogIQ Power Supply is a 24 Volt dc control
system designed for 2-wire 24V dc actuators in a
natural ventilation system.
Operating from a 230 V ac 2.0 A supply, the NV LogIQ
Power Supply can deliver 4.8 A (NPS00010002) for
short periods to motorised actuators.
The NV LogIQ Power Supply can be mounted locally
to the devices to be operated or in a centralised, plant
room location. Each NV LogIQ Power Supply can
operate independently or can be linked to others to
produce a networked control system.

Care should be taken whilst the cover is removed to protect against damage to the internal electronic assemblies and light pipes. 1.3. Location The NV LogIQ Power Supply is intended for indoor use only. The unit is environmentally rated to ingress protection IP20 and should not be located where exposure to damp/moisture or significant amounts of dust is likely. In particular, do not mount the controller in extreme environments such as cold rooms/ovens and those areas classified as having potentially explosive atmospheres. -

1.4. Fixing Mark through the mounting holes (3 off) on the NV LogIQ Power Supply base plate assembly. It is important to drill pilot or fixing holes of the suitable size and employ plastic plugs or cavity fixings when necessary. To firmly secure the base plate, make use of pan head or countersunk screws that are of the appropriate size.

Page 8: Connections
Connections 3.1. Assembly and Mains Connection Wiring to the NV LogIQ Power Supply can be direct to the unit via the cable glands entry points. Alternatively for cosmetic flush/surface mount applications the wiring can be passed through the cavity located in the rear of the NV LogIQ Power Supply. It is recommended that the required number of cable entry glands are assessed and fitted at this point. Blanking plugs and 22 mm glands are provided for this purpose. -

3.3. ‘DYO/DYC’ - Open and Close Day/Day (VFC) Input The ‘DYO’ & ‘DYC’ (Day to Day) functions are activated by means of an external volt free contact (VFC) signal (usually provided in the form of a momentary switch). An asserted input is used to manually open or close the connected actuator (via 24V dc actuator drive output connection). -
