Wireless Comfor t Inter face

Message to Homeowners

Congratulations on choosing the Emerson Blue Wireless Control System!
This system features an intuitive Comfort Interface that utilizes wireless
technology for precise and reliable temperature control found in all
Emerson products.

The Emerson Blue Wireless Control System consists of a Comfort

Interface, Equipment Control Module, Return Air Sensor and optional
Indoor/Outdoor Remote Sensors (F145RF-1600). The Comfort Interface

provides a large, uncluttered display for adjustments to your home’s

temperature, humidity, and system conguration. Powered with batteries,

it communicates wirelessly to the Equipment Control Module and

Return Air Sensor (located near your furnace and air handler). For added

performance, this system can be congured to work with up to 3 indoor
and 1 outdoor Remote Sensor(s) (sold separately).

When “Change

” appears in the display, a new set of premium brand

AA alkaline batteries should be installed. If the house will be unoccupied

for an extended period, it is recommended that new batteries be installed
before leaving.

Need Help? For assistance with this product, please call 800-284-2925.
