About the 4500 Thermostat
The Ademco 4500 thermostat provides control for both heat and air
conditioning. It is intended for use with Ademco security systems
that include the enhanced 4286 phone module. You can set the 4500
thermostat using any Touch-tone phone, either on premises or
remotely. The 4500 thermostat is not a replacement for the existing
thermostat, which remains in the installation, but can be selected to
provide a “set-back” function whenever the system is in the ARMED
AWAY mode. The existing thermostat controls premises temperature
while the security system is DISARMED, or in ARMED STAY mode.
Saving Money on Energy Bills
An important benefit of combined climate control and security is
potential energy cost savings. During the heating season, you can
“set-back” the 4500 thermostat for times when you are away from
home by putting the security system in the ARMED AWAY mode.
Our set-back feature lets you turn down the thermostat when the
house is empty automatically, when you arm the security system in
the ARMED AWAY mode.
During the cooling season, you can set the 4500 thermostat for a
higher temperature than the existing thermostat for times when you
are away from home, to save on cooling costs by putting the security
system in the ARMED AWAY mode.
In both cases you can call home to adjust the set-back temperature
that is in effect while the system is in the armed away mode.
The 4500 Thermostat Provides Comfort and Convenience
Heat or air conditioning in vacation homes can be remotely set and
monitored by phone. For example, heat can be turned up at a ski
cabin before guests arrive. The owner can also call-in to the system to
check that the indoor temperature is being maintained while the
premises are vacant. Users can set the air conditioning by calling
home just before leaving work. Once access to the security system
has been established, the ambient temperature will automatically be
announced if the installer has programmed this function. The
following sections describe how to use the 4500 thermostat.

2
How the 4500 Thermostat Works With Your
Present Thermostat
The 4500 thermostat works in combination with the original
thermostat installed on the premises.
While the premises is occupied, the security system is usually armed
STAY or DISARMED, and the 4500 thermostat will be inactive. The
original thermostat can be used as usual to set and adjust your
premises temperature.
When controlling a heating system, the set-back temperature setting
of the 4500 thermostat must always be set to a lower temperature
than the original thermostat. This way, the 4500 thermostat will
turn down the heat when the security system is ARMED AWAY.
Alternately, when controlling an air conditioning system, the set-back
temperature setting of the 4500 thermostat must always be set to a
higher temperature than the original thermostat. This way, the 4500
thermostat will allow the ambient temperature to rise when the
security system is ARMED AWAY.
If the pre-existing thermostat has a built-in clock and schedule, the
schedule can be used to set the times you “wake,” “leave,” “return,”
and “sleep.”
Note: The “leave” time should be set for the latest time that you
would expect to leave the premises. The “return” time should be set
to the earliest time you expect to arrive at the premises. If you leave
earlier or return later than scheduled times, the 4500 thermostat will
adjust the temperatures accordingly.
In summary, the 4500 thermostat allows you to:
• Set back the temperature (to that set in the 4500 thermostat)
automatically by arming in the AWAY mode when leaving home.
• Resume normal temperature (as set by the existing thermostat)
automatically by DISARMING the system when returning home.
• Check the temperature by phoning in from a remote location.

Front Panel Controls
As you can see from Figure 1 below, there are two controls and one
indicator on the front panel of the 4500 thermostat:
HEAT <> COOL BYPASS <> ACTIVE
123
Figure 1. 4500 Thermostat Controls and Indicator
1. HEAT/COOL Switch
This switch is used to set the control mode of the 4500 thermostat.
The mode can be set to either HEAT or COOL. This is the same as
found on most thermostats. For premises that only have heat or air
conditioning but not both, the proper mode should be selected with
this switch, and the setting should not be changed.
2. ACTIVE/BYPASS Switch
This switch is used to activate and deactivate the 4500 thermostat.
When this switch is set to the ACTIVE mode, the 4500 thermostat is
able to set back the room temperature when the security system is
ARMED AWAY. BYPASS is used to bypass the 4500 thermostat.
When bypassed, the 4500 thermostat cannot change the room
temperature.
• To use fan alone on your thermostat, put the 4500 in the BYPASS position.
• You will not be able to adjust room temperature by phone when the 4500
thermostat front panel switch is in BYPASS position.

Front Panel Controls (cont’d)
There are several uses for the BYPASS switch function:
• Allows the user to go back to their original thermostat at any
time.
• Allows heating/air conditioning service people to bypass the 4500
thermostat during servicing and maintenance work.
• Allows switching back to the original thermostat if the security system is
not working or is being serviced.
3. ACTIVE/ BYPASS Controls Indicator
This yellow LED indicator shows the status of the 4500 thermostat.
• When the ACTIVE/BYPASS switch is in the ACTIVE position, the
LED will be steadily on.
• When in BYPASS, the LED will be steadily off.
If there is a problem with the wirin
g
to the 4500 thermostat, the LED will flash,
and you should call your alarm installation or service company for service.

The 4500 measures the temperature of the surrounding air as well as the wall
that it is mounted on. It may provide a slightly different reading than a
thermometer or another thermostat mounted nearby.
This can be due to nearby sources of heat or drafts, sunlight, and varying
accuracy of existing thermostats. Unless the reading is off by more than
4°F, this should not be a cause for concern.

Controlling the 4500 Thermostat by Phone
The phone access feature of the Honeywell security system provides a
number of capabilities to the user:
• To adjust the ARMED AWAY set back temperature of the 4500
thermostats over any phone.
• To turn off the set back function for a single ARMED AWAY
period, or turn it on again if necessary.
• To control two 4500 thermostats in a single installation.
A Thermostat Mode voice menu can be activated after accessing the
security system by phone.
To Enter the Thermostat Mode Menu By Phone
1. Obtain access to your security system by phone according to the
instructions for phone access provided with your security system.
You will need to enter the 2-digit phone code provided by your
installer, and your 4-digit user code when you are calling from
outside, or whenever prompted by the system.
2. You will now hear the announcement of the security system
status followed by the ambient room temperature (if installer
has programmed this particular option).
3. Wait until the security system completes the status announce-
ments. When prompted by the system, press:
The security system phone access module will announce all words
denoted by quotation marks and italicized as follows:
• “THERMOSTAT MODE,” followed by whether “SET-BACK” is
“ON” or “OFF”, and whether the 4500 thermostat is set for
“HEAT MODE” or “COOL MODE.”
• The temperature setting of the 4500 thermostat that is in effect
when the security system is ARMED AWAY.
A menu of thermostat related end-user commands will be annunciated.
The following sections: Adjusting the Set-Back Temperature of the
4500 thermostat, Turning the Set-Back On and Off, Using Two
4500 thermostats With Your Security System, and Exiting
Thermostat Mode explain the use of the thermostat mode commands.

Adjusting the Set-Back Temperature
of the 4500 Thermostat
Keep in mind that the on-premises existing thermostat is set to the
desired temperature for when the building is occupied. The 4500
thermostat is used to set the set-back temperature for when the
premises is unoccupied and the security system is in the ARMED
AWAY mode.
The 4500 thermostat is set from any Touch-tone phone, either on-
premises, or by calling in when away.
1. Make sure that the front panel switches on the 4500 thermostat
are set correctly.
• The ACTIVE/BYPASS switch must be set to ACTIVE, and
• The HEAT/COOL switch must be set for the desired mode of
operation.
2. Enter thermostat mode as described on page 5. A menu of user
commands will be announced.
3. When you hear the prompt, “To change temperature, enter 1,”
Press during a pause in the thermostat mode menu
announcement.
The system will announce “Temperature set to 65,” for example.
4. Next, it will announce “Enter new temperature.”
If you want to keep the present set-back temperature, 65 degrees
in this example, just press .
5. If you want to change the set-back temperature point, you can
then enter a new temperature:
for example.
You have now set your unoccupied premises temperature to 61
degrees. The system will then announce the change of set point.

Setting the Set-Back Temperature
of the 4500 Thermostat (cont’d)
6. The new ARMED AWAY (set-back temperature) point will be
announced. This is the temperature the 4500 thermostat will
maintain when you are away from the premises. The set-back is
turned on only when the security system is ARMED AWAY.
The system will announce “Armed away temperature set to 61.”
7. Next, it will repeat “Enter new temperature.”
If you want to keep the present set point, 61 degrees in this
example, just press .
If you make an out-of-range temperature setting, a buzzer sound
will indicate to you that you made a mistake, and you will be
prompted again to enter the desired set point.
You have now set your ARMED AWAY temperature to 61 in this
case, and the phone module will echo back the change to verify.
8. If you are all done with the settings, and now want to arm or
disarm the security system, wait for the “To exit enter zero”
menu announcement and press .
9. At this point, you have adjusted the set-back temperature and
the new setting has been echoed back. Your options now are:
• to wait for the menu to be announced again in case you want to
review or change the thermostat settings.
• to just hang up the phone.

Turning the Set-Back On and Off
The set-back feature of the 4500 thermostat works automatically
when you leave the premises and the security system is ARMED
AWAY.However, sometimes you may want to override this feature.
You can turn off the set-back at any time, while still on the premises
or off.
For example, on a very hot day, you may want the premises
temperature to be restored to the more comfortable normal settings
by the time you return home from work instead of remaining at the
more economical set-back temperature until you arrive. You would do
the following:
1. Call the security system before returning home.
2. Enter your 2-digit phone code and 4-digit user code as requested
by the system.
3. Press to enter the Thermostat Mode Menu.
4. At the “To Turn Set-Back Off, Enter 3” prompt, press .
This command temporarily deactivates the set-back function until
you return home.
5. You can exit the Thermostat Mode at this point by pressing
at the exit prompt.
6. The premises cooling system will now be under the original
thermostat’s control with the premises temperature being lowered
to the more comfortable setting.
When you turn off the set-back, you are only doing so temporarily.
When you return home the thermostat mode menu resets itself
automatically so that when you again exit the premises with the
security system in the ARMED AWAY state, the premises
temperature will go to the programmed 4500 thermostat setting.
In the example above, if you change your mind and decide not to
return home early, you can turn the thermostat set-back to on again
by phone.
