High Performance

The Sentinel Econiq S benefits from the latest high efficiency, ED/DC backward curved impeller design, ensuring the lowest possible energy consumption, ultra quiet operation and an exceptional performance range to houses with a floor area of up to 360m2

With a high performance of 600 m3/hr at 150Pa while still achieving almost 93% heat recovery. The fully automatic capability of the Econiq range means that adequate ventilation is always achieved.

Integral Humidity Sensor

The integral humidity sensor increases speed in proportion to relative humidity levels, saving energy and reducing noise. The sensor also reacts to small but rapid increases in humidity, even if the normal trigger threshold is not reached. This unique feature ensures adequate ventilation, even for the smallest wet room. The nighttime relative humidity setback feature suppresses nuisance tripping as humidity gradually increases with falling temperature.

Digital Controller

A digital controller is supplied fitted to the unit allowing multiple options on programming and controllability, including 4 x Integral infinitely variable fan speed control on supply and extract there is also an optional kit allowing you to remove the controller from the unit and wall mount in your chosen location

There is also a pin number facility to prevent accidental resetting of commissioning settings

App Control

The Vent-Axia Connect smartphone application allows full control with a multitude of functions from automated to fully adjustable from the comfort of the sofa on iOS and Android smartphones

Orientation

This unit can be electronically changed from right to left hand orientation

Spigot Options

The 200mm Spigots may be re-positioned from a vertical to a horizontal connection or a combination of vertical and horizontal connection.

100% summer By-pass

During hot weather you can activate the summer By-Pass that will only bring the filtered air in at external temperatures allowing you to naturally cool your home

Low Noise Levels

The Lo-Carbon Sentinel Econiq is one of the quietest systems on the market, with a noise level as low as 15.5 dB(A). This is facilitated using an internal acoustic enclosure

Demand Control Ventilation

The Vent-Axia Connect smartphone application allows a multitude of functions to be adjusted from the comfort of the sofa, available on iOS and Android.

BMS

The BMS capability is also ideal for those commercial applications where landlords or property managers want to monitor and optimise building performance and maintenance.

The Kinetic BMS can provide status information and its self-diagnostics can report if any fault is found.

Filtration

The unit comes supplied with ISO 60% Coarse (G4) which can filter out sand, fine hair, and particles larger than 10μm.

Additional filtration can be achieved with a selection of optional supply air filters (extract still use G4)

• ePM10 (M5), which can filter pollen, stone dust, and particles smaller or equal to 10μm
• 5 (F7), which can filter out mould spores, bacteria and particles smaller or equal to 2.5μm.

Comfort Cooling

For scenarios where a cooling facility is required the optional Econiq Cool Flow kit is available

• Up to 3.78kW of cooling provided
• Activated automatically at 24°C to prevent overheating to meet Part O and TM59
• Lowers fresh air supply temperature from ambient temperatures by up to 21°C

Frost Protection

Automatic frost protection effective to -20°C

Fresh air programme

Evening Fresh’ turns the unit to maximum speed with the bypass

operational for 2 hours or until the user comfort temperature is

reached (default 21°C).

Night-time Fresh’ will run the unit at maximum speed with the

bypass operational throughout the night or until the dwelling

reaches minimum temperature (default 14°C).
