Green-Vent Solar has been specifically designed for New Zealand's climate.
The Green-Vent Solar is a solar powered vent that is controlled using a humidistat and a thermostat to ensure it runs only when required. The vent does not require wind to operate, has a fully adjustable solar panel, is extremely quiet and will keep your home cooler in summer and drier in winter.
During summer the temperatures inside New Zealand homes can exceed 50°C in roof spaces, resulting in elevated temperatures as high as 30°C in living areas.
During winter the roof space temperatures can drop to 15°C with the internal temperature dropping even lower. This is when condensation and moisture start to form.
Controlled by a humidistat and a thermostat, the Green-Vent Solar will automatically switch on when temperature in the ceiling space reaches 27°C and switch off when it reaches 25°C. It will also switch on if the roof space reaches 75% relative humidity and switch off when the roof space reaches 65
The Environment Control System (ECS) is an automated system for running the fan when environmental conditions demand it. The system is powered by a 12V solar panel so if there is no sun, the unit will not operate.
However, you can plug the ECS into mains power (see below for information) using the transformer (included). The fan will run on solar power when it has sunlight, otherwise it will run on mains power and only run for eight minutes every half hour.
Electrical requirements for mains power operation (optional)
To set up night time moisture control you will need the services of a qualified electrician to install a 12V transformer (to be sourced in NZ).You can plug the ECS into mains power (separate transformer required) which will then allow the ECS unit to control the Green-Vent Solar when there is not enough sunlight on the solar panel, such as at night.
