I have a Lifebreath RNC155 HRV with a Lifebreath BC-02 dehumidistat.
Despite following the instructions for the BC-02 and the HRV to turn off this feature, the HRV fan continues to run for 3 minutes every 6 hours, or 4 times a day.
How can I disable this feature so that the fan does not start every 6 hours, yet the fan can still be started with the controls in the bathrooms?

any chance this is the defrost cycle running on the HRV?
