02 About The Unit
The energiSava 200 is a whole house heat
recovery unit which works by continuously
extracting stale, moisture-laden air from the
“Wet Rooms” of the apartment or a house -
the kitchen, bathroom and en-suite rooms -
and ducts this to a central unit. This extracted
air passes through a high eciency counter-
ow heat exchanger before being ducted to
the outside. Fresh air is drawn into the unit
from outside, which is warmed by the heat
exchange cell and delivered into the living,
dining and bedroom areas.

instructions before beginning the installation
process.
PRE-INSTALLATION CHECK LIST
Make sure that the unit can physically t in to
the desired location.
The energiSava®200 unit should be
situated so that access for maintenance or
replacement of parts is possible. Make the
ductwork runs as short as possible. Having
the most direct route and using as few
bends as possible will reduce air resistance
and improve the eciency of the unit.
SAFETY AND RECOMMENDATIONS
• All wiring must comply with Building
Regulations and the current I.E.E. Wiring
Regulations (BS7671) or the equivalent
standards for your country. The nal
installation should be examined and tested
by a qualied electrician.
• Precautions must be taken to avoid the
back-ow of gases into the dwelling from
the open ue of gas or other fuel-burning
appliances.
• Make sure the mains supply complies with
the rating label for voltage, frequency and
phase.
• This appliance can be used by children
aged from 8 years and above and
persons with reduced physical, sensory or
mental capabilities or lack of experience

Control Options
Frost Protection
When the cell temperature in the unit falls below
5ºC the unit automatically warms the cell with
extracted air to prevent the formation of frost.
Boost - Switch Live
The energiSava 200®comes with Switch Live
as standard. It is an automatic function, sending
the unit to boost when the bathroom or kitchen
light is on.
Summer Bypass
The summer bypass helps reduce the air
temperature coming into the dwelling during the
summer months. It is an automatic function and
operates when the supply air temperature to the
property is above 25ºC.
Intellitrac®Humidity Tracking
When the energiSava®200 unit senses a rise
in humidity, caused by increased moisture
generation such as through cooking or
showering, the extract and supply airows will
slowly begin to increase in direct proportion to
the increase in humidity.
It will then automatically track back down again
when humidity falls. This controls condensation
quietly and eciently.
Boost - Remote Control
The energiSava®200 unit also comes with a
remote control switch which can be used at any
time to send the unit to boost for 20 mins (see
page 13).

Ducting Conguration
See page 10 for duct connections to the unit/airow directions
FIRST FIX - Installing ductwork and electrical supply
1. Locate external terminations (supply and extract) in accordance with the latest addition of
the Domestic Ventilation Compliance Guide.
2. Ductwork within house Ø125mm - maximise duct size where possible. Make sure that the
ductwork is insulated in unheated spaces. Minimise exible duct.
3. Locate the mains supply within 1m of the location of unit. The position of the electrical
power supply or unit (a fused switched isolator) must not be mounted above or closer
than 1m to a cooker where it could be aected by excessive heat or moisture.
4. Make sure that there is room for the MVHR unit. The unit is designed to be mounted
horizontally on a ceiling or the underside of a ceiling slab.
5. Also make sure that there is a free space at the front of the appliance for cleaning the lter
