33 The Thermo-hygro Sensor An ideal mounting place for the thermo-hygro sensor would be the outer wall beneath the extension of a roof, as this will protect the sensor from di rect sunlight and other extreme weather conditions. To wall mount, use the 2 screws to affix the wall bracket to the desired wall, plug in the thermo-hygro sensor to the brac[...]

35 For best results, the rain sensor should be securely mounted onto a horizontal surface about 39.37” (1 meter) above the ground (or higher) and in an open area away from trees or other coverings where r ainf all may be reduced causing inaccurate readings. When securing into place, check that rain e xcess will not collect and store at the base o[...]
