Overview

Comfort Call allows you to call and ‘talk’ to your compatible thermostat. Monitoring
and controlling your thermostat is now simple and easy from any phone, from
anywhere.

Comfort Call employs the latest in voice recognition and synthesis technology. It can
tell you the indoor temperature of your home and the outdoor temperature, provided
there is a working outdoor sensor connected to the thermostat. Once on the phone
with your system, you may tell your thermostat to change to your preset Comfort
Settings or go into your preset ‘unoccupied’, Energy Savings Settings (page 15).

Comfort Call consists of two parts: A base station (page 6) that connects to the phone
line and a RF Wireless Module that plugs into your compatible thermostat (page 5).

Once Comfort Call answers, you will be prompted to enter a Security Access Code.
This code is preset to 1111. You may change this code to any four digit number, if
desired (page 13).

Some homes may have more than one thermostat. If there is more than one
thermostat, Comfort Call will have a menu option to access up to four different
thermostats (page 16).

As an added feature, some of our compatible thermostat models allow for the remote
control of an auxiliary output on the thermostat. This auxiliary output may be
accessed and controlled from Comfort Call as well (pages 17 and 18). An example of the
use of this auxiliary output: The output is connected to a Powerflash Interface PF284
to turn on or off the indoor lighting wirelessly.

Overview cont.

Comfort Call requires an analog telephone line. If this system is installed at a primary
residence, then the ring selector on the base station should be set to pick up the line
after seven rings (page 10). With this setting, Comfort Call will not answer before an
occupant is likely to pick up the phone.

If an answering machine or fax machine is connected to Comfort Call, then the
answering/fax machine should be set to pick up before Comfort Call (the ring selector
is set to seven rings). In the case of a connected answering machine, after the tone to
leave a message is heard, the user enters the Comfort Call security code. Comfort
Call will release the answering machine from the line and control of the thermostat is
now possible.

In the case of a fax machine, after the ‘handshake’ tones are heard, there are
moments of silence; during this silent period the Comfort Call security code should be
entered. Comfort Call will release the fax machine from the line and control of the
thermostat will be possible.

Please note that some phone services provide a ‘voicemail’ answering service. These
services release the home phone line after a preset number of rings and transfer the
call to an internal voicemail system. Comfort Call is not compatible with this type of
voicemail system.

Comfort Call is a solution for people who do not have the same occupied patterns
every day for their homes. It is also a convenient way to call ahead to make
sure the primary or vacation home is comfortable upon arrival.
