This manual covers basic GroWeather/EnviroMonitor installation, including 
how to connect your sensors to the sensor interface module (SIM) and how to 
power your unit. Instructions on installing/mounting sensors and other sys-
tem components (such as the Alarm Output Module) are contained in the man-
uals for those products. This manual does include several installation drawings 
which depict typical GroWeather/EnviroMonitor installations and should help 
you connect all of your components correctly.
