- 100% programmable and adjustable supply and extract rates
- Night time set back
- Dimensions (HxLxW): 200 x 570 x 895 (mm)
This unit requires 2 x G3 filter with an optional F5 filter
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 pre-set the speeds to any required airflow within the performance range.
Boost can be achieved with almost any type of sensor or switch including momentary.
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 night time relative humidity setback feature suppresses nuisance tripping as humidity gradually increases with falling temperature
Constructed of galvanised steel and is fully insulated
The unit has 2 x low energy, high efficiency EC/DC motors
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.
The Condensate drain is through the 'atmosphere' 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.
In addition to a choice of compatible ducting systems a full range of controls, sensors, in-line silencers, floor/wall/ceiling inlet and outlet diffusers are available to complete the installation.

How to install a Vent Axia horizontal 200ZH
Vent Axia 200ZH Wiring Requirements
- 3amp switched spur beside unit
- Digital controller- Comes complete with 15 meter of 6 core alarm cable with a RJ45 connection
- Optional boost switch - 3 core 1.0mm cable from recessed single box to unit(recommended if bathrooms are further than 10 meter
- Further optional include - light switch, vent-wise controller,
- The low and high speed levels can be adjusted using the digital control
- further controls include- night time set speed set back - timed boost- sensor control - humidity sensor control - tempature control - summer bypass control - fault indication - filter indicator
- Position vent axia 200zh unit on floor or ceiling
- Install wiring for controllers (see bottom of page for further details)
- Install condensation drain from unit to internal or external drain
- Install wall /Soffit vents or roof vents (Minimum 1.5 meter apart) Pipes are 125mm diamater
- Position distribution boxes in the chosen location (proverbially in a central location minimising duct lengths )
- Install silencer (if specified) to air supply distribution box
- Install solid rigid ductwork and between distribution boxes and MVHR unit, (If possible allow for insulated flexible ductwork for final connections of MVHR unit )
- Install radial pipe into the distribution box ,
- Cut to length and install pipe into ceiling plenum, (insure you install rubber seal onto pipe) secure pipe in place with fixing band or pipe clips
Warning! There can be either one or two pipes going from the distribution box to the plenum depending on the required airflow , Always check plan that will indicate 1 or 2 pipes Install insulated rigid or insulated flexible ductwork to external vents Seal all open pipes to prevent debris and moisture ingress
- Trim ceiling Plenums to height of plasterboard (Easier to do before plastering ceilings)
- Install air valves to plenums (slightly open valve by two turns)
- Install all controllers
- Check that condensation drain has been fitted
- Switch unit on and follow the set up procedures
- Check air flow rates and commission system
Initial Design -
Pre designed plan - Please follow the plan ensuring the correct number of pipes to each area - Please note the plan is only a guide and you may have to reroute pipe work differently and reposition valves to suit layout of rooms
No Plan - If a design is not possible due to renovation, Retrofit or properties with multiple obstacles simply follow the listed recommendations
We would recommend that you
Install 2 x pipes from the distribution box to the room air plenum if air flow requirement exceed 10 L/s or if length over 15 meters
Install 2 x pipes from the distribution box to the air extract plenum in the main shower rooms and Kitchen
All other areas only require a single pipe from the distribution box to the room air plenum
Radial ductwork is suitable to be fitted below your loft insulation providing superior heat retention Insulate any ductwork or Manifold/ Distribution boxes with a minimum of 25mm thermal duct wrap that go above insulation in unheated attic spaces
Slim-line manifolds are suitable for installation to concrete ceilings and only require a 100mm service void
Position supply plenums approx. 500mm from corner of wall (avoid areas above beds and wardrobes)
Position extraction plenums to outside of showers and above kitchen sink (not cooker)
Only extract from a room with a open appliance (stove) if there is a supply with equal or higher airflow
