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.

2.0 General Overview

2.1.1

2.1.2

2.1.3

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.
