Energy Consumption is at an all time low with CV3. It costs less than two cans of baked beans to run for the entire year (it's just 97p!) and it's also got an excellent SFP performance for new build dwellings (See PCDB Information). I have used Fastlec three times each time I have found them to be efficient fast and happy to give you information on their products." Consider application each and every time as where and how you install a fan impacts on it's performance e.g. a fan which goes through the wall will performance differently to one that is installed in a ceiling with 3m of flexible ducting. Don't miss the new 'Do Not Disturb' functionality that allows you to define a period during which the fan won't boost eg. 10pm - 6am to prevent night-time running. If a product fails after six months of receiving the item it is considered a warranty claim and is the responsibility of the buyer to pay for the return postage. We will then dispatch a free-of-charge replacement once the original has been received and tested. Book a DPD Return Here

It's ultra ultra-efficient. Energy Consumption is at an all-time low with CV3. It costs less than two cans of baked beans to run for the entire year (it's just 97p!) and it's also got an excellent SFP performance for new build dwellings. This fan is suitable for bathrooms, WCs or kitchens, in apartments or houses, for the wall or the ceiling. Designed for new and existing homes CV3 is the newest, smartest continuously running (dMEV) fan from Greenwood Airvac. It can easily be set up, configured and controlled via your smartphone. With airflow sensing technology it will sense, react and extract to the correct performance for each installation. This helps eliminate mould and condensation caused by poor fan performance.The second introduction of SMART Technology was Greenwood HumidiSMART™ which has taken humidity controlled ventilation by storm - now available in Unity CV2GIP, Omnique, Samika, Vireo MVHR and Centair CMEV.4e. t's a 'one fan' solution for bathrooms, kitchens, utility rooms and wc's. This makes it easy for large scale planned new build and maintenance programmes. The very first SMART Technology launched was Greenwood CommissionSMART™ Technology on our iconic Unity CV2GIP product. Unity CV3 features a new and logical approach to timer operation. Its SMARTer beacause in contrast to traditional timers, it looks at the duration of occupancy to define running time rather than have a fixed running period. This removes nuisance running noise, especially at night, and unnecessary energy wastage and heat loss typically associated with traditional timers. SMART Technology comes in sensors, controls and design features within our products, usually our GIP product range.

The third SMART technology in practise is Greenwood CommissionSMART™ designed into Vireo, a brand new range of heat recovery ventilation units that offer the easiest and fastest commissioning process ever! Traditional humidity sensors usually provide ventilation when it is needed, but it is often when it isn’t needed that the fan still comes on... WHY???? Because it uses a generic base line to activate the fan e.g. 65%. If it happens to be a hot summer's evening and the windows are open in the bathroom, this will activate the fan therefore causing nuisance running and unnecessary energy consumption! Greenwood HumidiSMART™ provides humidity controlled ventilation without nuisance running (in the middle of the night!), unnecessary heat loss and energy consumption from homes. It activates ventilation in response to man-made spikes in humidity only because it works with the 'real time' installed environment and knows exactly what the normal level of humidity is at any given point in time. It then uses this as its base line to look for spikes. Unity CV3 is the newest, smartest continuously running (dMEV) fan from Greenwood. Designed for new and existing homes, it has been designed to take on board the continued importance of reducing energy consumption, easy compliance with Regulations and contribution to well-being by eliminating nuisance noise and contributing to improving indoor air quality.
