During showering my ventilation system was sucking warm air out of my living room. This was then triggering the thermostat to heat up the living room again. This was a waste of energy and bad for the environment. With the Open AIR Valve I can now shut off the living room and direct all the ventilation to a single room depending on the circumstances. This while being compatible with HA so I can program any behavior I want.
The Open AIR Valve has two notches on the side of the housing. When installing your Open AIR Valve these need to be lined up with the side of the Ducobox.
Don't rotate the Open AIR Valve disc by hand! Install the Open AIR Valve Disc the way you received it. The location of the disc is set to a location where it will automatically home after installation. If you install your own sensors please place the Disc back to the approximate location you received your Open AIR Valve in.
For ordering the right quantity of foam: you have 7 inlets in a ventilation box of the green brand. if you order two valves you need 5 foam blocks. so 7-number of valves= amount of foam blocks you need.
The Open AIR valve can only fit one sensor! And is placed where the current sensor is placed in your ventilation system. So if you have two physical sensors in the same ventilation hole you need to chose. If you want to use RH and CO2 then the combination sensor is the only option.
The original sensors do not fit my sensor housing!!! I don't own any original sensors so I cannot build/test with them.
If you add the housing only option you receive: A sensor housing, 3 bolts & a shorter cable.
External Valve Housing: This is an 3D printed housing + power supply. This makes your valve mountable outside a ventilation box.
To install the external valve housing + valve you need to bring the following yourself: 1: A 125mm flexible tube. This can be any standard 125mm un-insulated flexible hose : Click
2: Hose clamps suitable for 135mm diameter. These can be standard stainless steel hose clamps for 60mm to 135mm diameter hoses. Click
3: A 12 Volt adapter with a 5.5x2.1mm jack, center positive. The power requirement for each valve is 2W. (12V >200mA) These adapters are commonly available and you might already have one.
4: Mounting hardware such as screws, bolts, and wall plugs, which should be selected based on the type of wall you are installing the valve on..
