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 behaviour 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.
When your order and you choose for the preprogrammed version: Please let me know in the order comments what kind of sensor you have! You can choose out of the following options:
SHT-20: (the same sensor as the original Duco RH sensor) If you look in the opening of the sensor housing and shine a light in the other side you should be able to read the soldermask SHT-2X.
SHT-31: This is a newer sensor this sensor is not backwards compatible with the original Duco Boxes.If you look in the opening of the sensor housing and shine a light in the other side you should be able to read the soldermask SHT-3X.
Co2 Sensor: You will know this.
Combination sensor: CO2 and SHT-31 in one sensor.
Comment format Example:
Valve 1: SHT-31
Valve 2: SHT-20
Valve 3: Co2
Valve 4: Combination
If you forget to let me know. The Valves are programmed without sensors.
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.
