Hello, do you have a broken Zehnder comfoair sensor and does your unit indicate a ETA or OTA fault even after a reset? You can't get a replacement due to the silicon crisis?

Then this might be a solution for you. Read thoroughly thru below!

This auction is for a replacement pcb only.

With this auction you only receive the pcb with the original smd sensor used by Zehnder themself and smd components already pre soldered to the board, like in the picture but WITHOUT the wiring. The pcb is reversed engineered by me and fully functional. For units that accept the sensor like in the picture. It is tested on the Q450 unit and should work on other (like q350,q450,q600,...) units too. If it's not working on your unit, your unit might need a firmware update.

You still need to recuperate your original wiring/connector and rubber gasket, then you need to solder the wires yourself according to a schematic and instructions as fixate (ideal in a epoxy mold, I can provide a 3D print) the new sensor board into the original rubber gasket.

It is possible to sent your original sensor for repair to me, but then there will be an extra 20€ fee for the soldering and moulding.

Each unit is sent out after testing, you receive a functional unit but you are responsible to handle the pcb according the ESD rules.

NEW:

It's possible to obtain a connector set ( Connector housing + 4 crimping pins) 3€ extra.
