4. ULE NIM Select a location near the variable speed furnace or fan coil where wiring from equipment can come together easily NOTE Do not mount NIM in outdoor unit The NIM is approved for indoor use only and should never be installed with any of its components exposed to the elements The NIM may be installed in any area where temperature remains between 32 and 158 F and there is no condensation Remember that wiring access is likely the most important consideration CAUTION ELECTRICAL OPERATION HAZARD Failure to follow this caution will result in equipment A damage or improper operation To prevent possible damage to NIM do not mount on plenum duct work or flush against furnace WIRING CONSIDERATIONS Ordinary thermostat wire is ideal when wiring the Evolution System shielded cable is not necessary Use 18 22 AWG or larger for typical installations Lengths over 100 ft should use 18 AWG or larger wire Cut off or fold back and tape any unneeded conductors Plan the routing of wiring early to avoid possible problems later NOTE ABCD bus wiring only requires a four wire connection however it is good practice to run thermostat cable having more than four wires in the event of a damaged or broken wire during installation The following color code is recommended for each ABCD bus connection A Green Data A B Yellow Data B C White 24VAC Common D Red 24VAC Hot It is not mandatory
