        Energysaver™ Datamatic Data logging bathroom fan SELV DMESQ50
a
 

Energysaver™ Datamatic, fully automatic 100mm (4") safe extra low voltage axial extract fan, for wall, ceiling or window fit applications, in bathroom or shower areas. Energy efficient ball bearing 12V DC motor requires only 2.9 watts of power when operating. Supplied as a complete kit, comprising tube fan, remote humidity sensor/transformer and external wall grille with integral back draught shutter.

The microprocessor records the following data in Real Time: Relative Humidity (RH), temperature, set point, vapour pressure, dew point, power interrupts, and every time the fan has run (plus cumulative run time total). Data is held for a rolling period of 420 days.

The Dynamic Humidity sensor is designed to operate when any rapid increase in the humidity is sensed. When the water vapour has been extracted and the room returns to the previous humidity level, the Dynamic Controller will switch off the fan.

a Construction
Wall fan – unit is housed within a standard 100mm diameter white plastic wall tube, which allows recessed fitting. Isolation transformer forms integral part of the dynamic humidity sensor controller and is contained within a single gang box. Supplied as a complete kit comprising tube fan, transformer/sensor and external grille with integral back draught shutter. This safe extra low voltage fan can be positioned in any location, even where water and earth contact is a possibility.

Window Fan – unit is housed within a casing with a 100mm spigot and integral silent mechanical backdraught shutters. Transformer and dynamic humidity sensor are contained in two separate single gang boxes. Supplied as a complete kit comprising of fan, transformer, sensor and window kit. This safe extra low voltage fan can be positioned in any location, even where water and earth contact is a possibility.

Motor
A 12V DC brushless, electrically commutated with sealed for life lubricated ball bearing motor. Energy efficient – only consumes 2.9 watts of power when running. Conforms to IEE 16th Edition SELV circuits. Isolated power supply conforms to BS3535.

Installation
The SELV fan unit may be fitted in either Zone 1 or 2 of a bath/shower room. The humidity sensor/transformer must be fitted in Zone 3 only (alternative models available with separate transformer and SELV sensor with or without Timer overrun if required). For maximum efficiency the fan should be sited at high level, as close as possible to the source of moisture. The sensor/transformer should be positioned to detect humidity as it is produced, ideally on an internal wall 100-150mm down from the ceiling and between the moisture source and the door of the room.

In many instances, a passive air vent, or an air brick, may need to be fitted to other cooler rooms within the property, in order to promote a good airflow throughout the dwelling.

Fitting Kits available:
WALL: All inclusive
CEILING: As wall but will require 100mm dia. ducting. We only recommend that this axial fan be ducted a maximum 1.5m. For greater distances, a centrifugal or in-line fan would be more appropriate. (see Centramatic and remote sensors data sheets)
WINDOW: All inclusive		 a a
