MOMENTARY ON/OFF COMMANDS

an output on or off for three sec-
onds. This feature can be useful
for operating low voltage control
systems (drapery motors, lighting
controls, etc.)
Enter an on or off time of 0 to get a 3
second output. For example, To turn a
unit 2 on for 3 seconds then off, press
UNIT-NUMBER, 2, TIME, 0, ON.
TEMPERATURE CONTROL
Your Model 1503 can control tem-
peratures of your heating and cool-
ing system, monitor the outside
temperature and detect high and low
temperatures in special situations.
Other appliances can be controlled
by temperature as well - such as a
bathroom heater or a ceiling fan.
Temperature control starts with
unit number 17. If you have two
heating and cooling systems, they
are usually unit numbers 17 and 18.
Your dealer will explain your par-
ticular installation.
MODEL 1101 PROGRAMMABLE ENERGY
SAVER MODULE
The Model 1101 Programmable En-
ergy Saver Module (PESM) provides
energy savings and convenience by
setting the HVAC system(s) to the
proper temperature based on whether
you are home, asleep, or away. It
can be controlled over the tele-
phone, and the temperature of the
home can be reported over the
phone. A freeze alarm feature will
cause a dial out if the temperature
falls below a preset level. (The
Model 1101 PESM has not been inves-
tigated by Underwriter's Laborato-
ries.)
The Model 1101 PESM is a tem-
perature sensor and control relay
in a small enclosure that mounts
near your central heating, ventila-
tion, and air conditioning (HVAC)
system thermostat. The PESM allows
the Model 1503 to read the tempera-
ture of the area that the HVAC
system controls. When you are away
from your home or asleep, the PESM
can be set to allow the temperature
to drift higher or lower to reduce
the operating time of the HVAC
system, hence saving energy dol-
lars.
The PESM provides an energy
saver function. When the energy
saver is on, the HVAC system is set
back, meaning that the temperature
is allowed to rise or fall to an
energy saving level. When the en-
ergy saver is off, your thermostat
operates normally. Your thermostat
