Step 1: Mounting the Controller

Your Controller can be mounted to any wall using the mounting hardware included. It should be mounted near your wireless access point. Plug it in with the included 12V Power Adapter.

Step 2: Mounting the sensor module

Locate the Environment Sensor(s) in a clean and dry location where it will sample non-stagnant air. If you are utilizing the light sensor for sun sensing, ensure the light sensor has a clear path to the sun or light source. The Environment Sensor is designed to be suspended with the light sensor facing up and hanging at canopy level. The Environment Sensor can also be mounted to a wall with the wall-mounting hardware.  Run power to the environment sensor with the included power extension cord and adapter.
