Model 1503 Owner's
Manual
4. HOME CONTROL
The home control features of the
Model 1503 make it easy and conve-
nient to control almost any light
or appliance from the console or
over the telephone. You may also
have your heating and air condi-
tioning (HVAC) system under control
of the system, which will allow it
to save energy dollars by setting
the temperature appropriately when
you are home, asleep or away. (The
Home Control functions have not
been investigated by Underwriter's
Laboratories.)
Furthermore, the Model 1503 can
be used to program lights to make
the home look occupied as a deter-
rent to potential thieves.
There are three methods that the
Model 1503 uses to control differ-
ent things:
1. X-10 Powerhouse
tm,
Leviton and
compatible modules for lights
and small appliances
2. Model 1101 Programmable En-
ergy Saver Modules (PESM) for
central heating and air condi-
tioning systems
3. Direct Relay Control (with or
without Model 1102 Expansion
Enclosure) for sprinklers,
lighting, electric heating, etc.
A MODEL 1503 VERSION 2 by itself
will control:
- 64 X-10 modules (four house
codes)
- 3 Model 1101 PESMs or direct
relay controls
for a total of 67 control points.
With 4 Model 1102 Expansion Enclo-
sures, the Model 1503 Version 2
will control:
- 64 X-10 modules (four house
codes)

relay controls
for a total of 128 control points.

MODULES
The Model 1503 controls lights
and appliances by sending commands
over your existing electrical wir-
ing to special switches, outlets
and modules, collectively referred
to as MODULES. Each module (or
group of modules) is assigned a
HOUSE CODE and a UNIT NUMBER so
that the Model 1503 can control the
modules individually. When a module
hears a command from the Model 1503
for its house code and unit number,
it executes the command.
The modules used for actually
controlling the light or appliance
are industry standard modules manu-
factured by X-10 USA, Inc. and
Leviton Manufacturing Co. Leviton
products are called “Leviton Decora
Electronic Controls (DEC)”. The
modules are sold by your dealer as
well as certain retailers such as
Radio Shack, Sears, Home Depot and
others. Any module that is “X-10
