INSTALLING THIS UNIT, CALL US ON:
Safety
Read and understand these instructions carefully before
beginning installation. The unit should only be installed by a
competent person.
Electrical Connection
The unit requires a continuous electrical power supply. Connection to
the fixed wiring must be made outside the unit in a suitable location.
The unit must be able to be disconnected from the mains supply
after installation. The unit must be earthed and a double pole switch
having a minimum contact separation of 3.0mm must be used to
provide isolation for the unit.
The power cable running into the unit must remain the supplied
flexible cable (not a solid core lighting cable]. If the power cable
becomes damaged, it must be replaced by EnviroVent, an authorised
service agent for your region/country, or a similarly qualified person in
order to avoid a hazard. Do not remove or tamper with any electronic
components inside the unit.
All wiring must comply with Building Regulations and the current
IET Wiring Regulations (BS7671 in the UK) or equivalent standards for
other countries. The final installation should be examined and tested
by a qualified electrician.
The unit is considered to be suitable for use in countries having a
warm, damp equable climate. It may also be used in other countries.
Electrical power is to be supplied to the unit through a residual
current device (RCD) with a rated residual operating current not
exceeding 30mA.

Location
Check there is space for the unit in your chosen location including
room for access and future servicing of the unit. The unit must not
affect the operation of open-flue appliances. Consider the external
vent locations in relation to open-flues from appliances e.g. boilers.
You must ensure the external supply grilles are positioned away from
open flues to avoid drawing harmful gases into the property. Consult
your local regulations or a qualified gas engineer.
Users
This unit is not intended for use by persons [including children] with
reduced physical, sensory or mental capabilities or lack of experience
and knowledge, unless they have been given supervision and usage
instruction by a person responsible for their safety. Children should
be supervised to ensure they do not play with the unit. Cleaning and
user maintenance must not be performed by children.

WIRING
The local isolator must be connected to the mains as
part of the fixed wiring. Connect the cores of the power
cable to the matching terminals on the local isolator
(3A fuse spur or similar).
The black switch live core of the mains cable can be
wired to a switch input such as a light switch. When
the switch is turned on, the boost function is engaged.
When the switch is turned off, the unit will return to
normal running mode. In this configuration a triple pole
isolator must be used.

About the energiSava®200
The energiSava®200 is an MVHR unit (Mechanical Ventilation with Heat
Recovery). It is ideal for small to medium sized properties with a kitchen
and up to 5 additional wet rooms. The unit is capable of delivering a
maximum airflow of 241m3/h (67l/s) and a maximum system pressure
in excess of 500Pa.
The unit will help to create a fresh and healthy living environment by
supplying filtered air into a property through supply valves. Moist, stale
air is removed out of the property through extract valves.
The heat exchanger inside the unit transfers waste heat energy from
the extracted air to the supplied air in order to improve the thermal
efficiency of the property and reduce heating costs.
The frost protection feature automatically uses the warm extracted
air to ensure the heat exchanger inside the unit does not freeze when
outdoor temperatures are below 5ºC.
The Intellitrac®humidity tracking function monitors the humidity levels
in the extracted air and will automatically increase the supply and
extract air flow rates when the humidity levels rise. Once the humidity
levels are lower the air flow rates will return to the normal rate.
The mechanical summer bypass feature automatically diverts
some of the supplied air around the heat exchanger at temperatures
above 25ºC to avoid the property overheating when the outdoor air
temperature is high.
The energiSava®200 includes a switch live function. When wired
through the lighting switch of a room (such as a bathroom) the unit
will enter boost mode whenever the light is turned on.

Installation
1. Hold the unit up to the chosen location and check there is space
for ducts, condensate drainage, filter and keypad access.
2. Once you are satisfied with the position, line up the two brackets
using the printed template then secure them to the mounting surface.
Use 5 8gx2.0” screws and 10 plasterboard plugs.
3. Mount the unit onto the brackets ensuring that it is fully supported.
4. Apply the two wing nuts onto the threaded studs then insert the
self-tapping screw into the hole and tighten it. This will ensure the
unit cannot be accidentally knocked off the brackets.

accordance with the Domestic
Ventilation Compliance Guide.
(Example RH unit configuration
shown).
Ducts to and from atmosphere
and through unheated spaces
need to be insulated.
For efficiency, all ductwork should
be as large a diameter as possible
(min. 125mm) and use rigid or
semi rigid duct.

SHOULD YOU ENCOUNTER ANY PROBLEMS
INSTALLING THIS UNIT, CALL US ON:
All maintenance and building works should be complete before
commissioning this MVHR unit. This will avoid any other major
disturbance to the installation or high volumes of dust or debris being
drawn into the system. Do not commission the MVHR unit until it is fully
installed including power, ductwork, internal valves and external vents.
MVHR systems must be commissioned in accordance with Approved
Document F of the Building Regulations for England and Wales.
Further good practice advice for the installation of MVHR systems can
be found in the latest edition of the Domestic Ventilation Compliance
Guide for England and Wales. For MVHR commissioning guidance in
other countries, please refer to the relevant local Building Regulations
for that country.
• Determine the required ventilation rates. For guidance see Approved
Document F of the building regulations for England and Wales.
• During normal running mode, press the SET button for 4 seconds
to enter commissioning mode. (Humidity and temperature sensor
input is disabled temporarily while the unit is in commissioning
mode).
• LEDs B C D will light and LED A will flash indicating that the extract
boost flow rate is being modified.
• Fully open all supply/extract valves then measure the air flow rate at
all system extract points using a calibrated air flow meter capable
of measuring in l/s or m3/hr.
• Add the extract rates from all rooms together then compare this
value to the calculated whole building boost extract ventilation rate.
• Use the + and - buttons to increase or decrease the flow rate in
order to meet the calculated whole building extract ventilation rate.

• Now adjust the individual valves to extract at the appropriate rate for
each wet room.
• Press the SET button once to move on to the next flow rate. The
flashing LED indicates which flow rate is being modified.
A: Extract Boost
B: Supply Boost
C: Extract Trickle
D: Supply Trickle
• Commission the unit in the order shown below, using the previous
steps for adjusting air flow rates and valves.
(When maximum speed setting is reached, the LED will flash faster.
When the minimum speed setting is reached the LED will flash slowly).
Step Flow Rate Actions
1Extract Boost Lock the valves.
Record the air flow rates.
2Supply Normal (Trickle) Lock the valves.
Record the air flow rates.
3Supply Boost Do not adjust the valves.
Record the air flow rates.
4Extract Normal (Trickle) Do not adjust the valves.
Record the air flow rates.
• When commissioning is complete for all four flow rates, press SET
for 4 seconds to return to normal running mode. If this is not done,
the unit will automatically return to normal running mode after 60
minutes of inactivity and the current settings will be saved.
