Installation
The HVAC module should be installed close to
the equipment being controlled. Do not install it
within a metal enclosure that might interfere with
wireless communications. Only standard 18
gauge thermostat wire is required to wire the
module to the equipment.
Two #6 sheet metal mounting screws are
included or the module can be installed with
double-backed adhesive tape.
