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.

Page 15

Link up to 4 Thermostats to 1 Base Station
Comfort Call will allow up to four thermostats to be linked with one Base Station.
This can be accomplished with additional RF Wireless Modules (ACC0434) installed at
each additional thermostat. The linking procedure for thermostats numbered two
through four is the same as described for a single thermostat (pages 6-9).
The Base Station will recognize the new thermostats and store them by number, in
the order that they are linked to the Base Station.
When more than one thermostat is linked, the main menu will add the prompt, “For
the next thermostat, press four, or say next thermostat.” Additionally, before the
status is given, the thermostat will say, “You are controlling thermostat number 1 (2,
3, or 4)” (page 14).
Page 16

Control of the Thermostat’s Auxiliary Output
Comfort Call has the ability to control the Auxiliary Output of a connected thermostat
if that thermostat has an Auxiliary Output configured for PROG (program) operation.
When the thermostat is configured and enabled to let Comfort Call control its
Auxiliary Output, the Base Station will automatically detect this. The main menu will
then add the prompt, “To control the Auxiliary Output, press 3or say: Auxiliary
Output” (page 14).
After pressing 3or saying, “Auxiliary Output,” the user will be given the Auxiliary
Output Status and asked if he/she wants to change it. This will be followed by a
confirmation (page 15). Additionally, the Auxiliary Output Status will be added to the
status report.
Please consult the thermostat’s Owner’s Manual for further details on configuring the
thermostat for this operation.
The auxiliary output of the thermostat may be connected to a 24v control module,
such as a X-10 Powerflash Interface, model PF284 (recommended wiring diagrams on, pages
18-20). This will give you the ability to control items such as lamps, wall switches,
jacuzzis, appliances, hot water heaters, security systems, etc. in your home with
minimal installation.
To see available X-10 products that can be controlled with a Powerflash Interface
PF284 contact or visit a retailer that carries X-10 products, such as SmartHome
(800.762.7846 or www.SmartHome.com).
