Use rh & temp triggers on auto mode. Set high temp to 79 degrees or so, low temp set to 0. For rh set high to 50% due to being in flower, low should be 0%. You can set minimum speed by switching from auto to off. I usually set my minimum at 3. Max speed of 10 is fine. You set that like minimum, but place the controller to on to set it. You follow all this? When done with the trigger settings, and minimum and max speeds set it back on auto. Setting alerts is similar.
