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.

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

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.
