Your home has continuously running ventilation Unity CV2GIP / CV2SVGIP (dMEV) fans
installed. This consists of locally sited extract fans that form part of a whole house
ventilation approach. These fans extract air on a continual basis from the following areas
(defined as wet rooms within Building Regulations) in residential dwellings –
•Kitchen
• Bathroom
• Utility Room
•WC/Cloakroom
• Ensuite Bath/Shower Room

The specific operation of your fan may vary depending on the way it has been installed.
The options are –
Trickle Speed: Operating on a continual basis.
Boost Speed: Activated manually using our GS2 switch or via the room light switch.
GS2 switch markings - Trickle (I) & Boost (II) Operation
Note: Other manufacturers switches may show different markings.
To maintain a healthy indoor environment the Unity CV2GIP / CV2SVGIP includes SMART
technology for Over-run Timer (Greenwood TimerSMARTTM)and Humidity
(Greenwood HumidiSMARTTM).
Greenwood TimerSMARTTM monitors the length of time that there is an occupancy
presence within a wet room (via the ‘switch-live’) and provides a fixed over-run time
period to best match the length of time that the ‘switch live’ is active (as shown below):
Note: The first 5 minutes will not activate an over-run.
This removes nuisance running noise and unnecessary energy wastage typically
associated with traditional timers.

Greenwood HumidiSMARTTM monitors the ambient humidity within the wet room
environment and looks for short peaks of humidity made by either showering or bathing.
This smart technology ensures that your Unity CV2GIP / CV2SVGIP is not on boost for
prolonged periods of time, removing nuisance running noise and unnecessary energy
wastage typically associated with increases to background humidity which naturally
occurs with the changing seasons.
To maintain good indoor air quality within the dwelling it is important that the fan
remains in operation at all times unless switched off for maintenance. (See section 4.0
Servicing / Maintenance).
Depending on when your home was built, background window trickle ventilators may be
provided in dry habitable rooms. Trickle vents should not be installed in the same rooms
as the fan, as overall ventilation effectiveness can be reduced.
Warning: 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 and knowledge if they have been given supervision or instruction
concerning use of the appliance in a safe way and understand the hazards
involved. Children shall not play with the appliance. Cleaning and user
maintenance shall not be made by children without supervision.Always isolate
fan from mains supply before cleaning. Do not use solvents to clean this fan.
Siting Notes: Where an open-flued oil or gas-fuelled appliance is installed in the
kitchen,extract ventilation can cause the spillage of flue gases. Care must be
taken to ensure ventilation is reduced appropriately, as set out in the Building
Regulations. Kitchens with solid-fuel appliances should not have extract fans fitted.
The CV2SVGIP fan must only be supplied via Safety Extra Low Voltage (SELV)
corresponding to the markings on the appliance.

cause the fan to automatically switch to Boost mode.
When humidity falls below a calculated threshold close to background levels, the fan
should return to trickle mode.
To identify current fan status, press any button to activate the panel. Upon
identification of control status, either press [ ] to activate or deactivate the Greenwood
