Hi everyone,
I have a CO2 level problem in my house. I decided to change hy HRV for one that would be more performant. I bought a Venmar EVO5 HEPA that I installed yesterday. Monitoring the CO2 level in the house, I think that I will need to unit to vary from "Continuous" mode to "Turbo mode". I would like that to happen automatically based on measured CO2 level. My CO2 detectors are Airthings Wave Plus, which have a well defined API, including IFTTT support. Could anyone provide a lead about how to connect that to some controller for the air exchanger? Any data about the 4 wire interface to the air exchanger? I read about resistive interface for fan speed on some Venmar units and I think it is more than just that as the unit communicate the exterior air temperature to the controller.
Thank you!
