It is recommended that the optimal height for installation is greater than the height of the pet. D: Installation of the controller power cord: connect the power cord with the host power hole, and then tighten the nut on the power cord clockwise. E: Hang the equipment according to the corresponding holes, and the heating device can be used normally after the power is turned on. B B: Choose the best location on the wall (near the end of the power cord) and drill a hole at least 20 mm in diameter to ensure that the power cord can pass through this hole. C: Please pass the power cord through the drilled hole, and then hang the controller in a suitable place. Then hang the controller in a suitable place (the controller is waterproof to IP55, try to avoid long-term use in the rain). - 06 - Product Features Smart Wifi Function HeatingShutdown Timer Temperature Adjustment LED "+Temp." +"-Temp."
