| APPLICATION

A Remote Temperature and Humidity (RTH) sensor paired with a Smart

Node results in a clean aesthetic in your space while minimizing

installation times. The RTH provides highly accurate temperature and

humidity values from your space and the Smart Node reports these values

to the CCU.

| PRECAUTIONS

Take all precautions normally taken when installing a thermostat

(e.g. not in direct sunlight, not on an exterior wall, not near heat

producing equipment)

Disconnect power before installing. Never connect or disconnect

wiring with power applied

Do NOT run RTH harness next to line voltage

Install in accordance with all State and local codes.
