Sentinel Kinetic MEV Unit 300ZH 449536 – Vent Axia

High efficiency, compact, horizontal, residential Mechanical Ventilation with Heat Recovery unit (humidity sensor version)

The Sentinel Kinetic Horizontal Range

A whole house heat recovery system with up to 81% heat exchange efficiency. An easily accessible heat recovery cube protected by two removable EU3 filters.

Incorporating two Lo-Carbon Energy Saving EC/DC motors ensures long life (typically over double the life of AC motors) and lowest possible energy use.

Fully insulated construction with built-in condensation drain. Specifically designed for new build constructions with a high level of insulation.

The Lo-Carbon Sentinel Kinetic Horizontal meets the latest requirements of the Building Regulations ADF for whole house system ventilation: System 4 – Continuous mechanical supply and extract with heat recovery.

The Lo-Carbon Sentinel Kinetic Horizontal models have three fully adjustable speeds and a purge setting (maximum airflow).

Supplied with the unit is a digital controller that can be used to preset the speeds to any required air-flow within the performance range.

Integral Humidity Sensor

The integral humidity sensor (” models) 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 night-time relative humidity setback feature suppresses nuisance tripping as humidity gradually increases with falling temperature. Acoustically lined – low noise levels from on 20 dB(A) @ 3m.

Multiple control options

Five volt-free pairs of switch terminals for sensor inputs allowing booting from a full range of Vent-Axia controllers – humidistats, PIR, timers.

Two terminals with 0-24V outputs allow 0V to 10V proportional control by sophisticated controllers such as CO2 sensors and proportional humidistats.

The optional Ventwise controller senses temperature rise in a bath/shower hot water supply and/or current in a cooker/hob electrical circuit to activate boost, ensuring additional ventilation when needed. Switch-live for boosting via light switches (220-240V AC) or manual Normal/Boost switches. This connection has the advantage of Delay-On and Delay-Off facility.

Delay-On enables you to prevent the Boost airflow between 0 and 10 minutes after a light switch has been activated.

Delay-Off allows the Boost airflow to continue after a light switch is turned off to ensure effective clearance of humidity. This timer is adjustable between 0 and 25 minutes.

Summer Bypass

An internal damper is activated when the outside temperature is less than the room temperature. The damper opens allowing cooler fresh air to bypass the Heat Recovery Cell and reduce the internal temperature towards the preset ‘ Temperature’. When the inside air temperature reaches the preset ‘ Temperature’ the bypass damper closes.

Frost Protection

In cold climates, there is a possibility of frost building up on the intake side of the heat exchanger. In order to prevent damage, the Kinetic reduces supply flow while maintaining extract flow at temperature down to -20°C.

Range Product Specification

The Lo-Carbon Sentinel Kinetic Horizontal models have 2 fully adjustable speeds and a purge setting – maximum. Supplied with the unit is a digital controller that can be used to pre-set the speeds to any required air-flow within the performance range.

The Sentinel Kinetic Horizontal models designed to be horizontally mounted under a slab, with access for servicing and maintenance from below. When mounted in an unheated area ducting must be insulated.
200 Z models are 200mm deep, including condensate and mounting bracket.
300 Z models are 300mm deep, including condensate and mounting bracket.

The condensate drain is through the ” end of the unit. Using the fittings supplied, the final condensate connection is made outside the unit and can be completed after installation.

Electrical and control connections are also made on the outside of the unit.
