WARNING:
●
If any plugs do not fit into the receptacle that you
are trying to plug into, Stop, the PSP300 is not
designed for this application.
●
If the cord you are plugging into the PSP300 only
has 2 prongs, STOP, not having
a ground wire is unsafe. Your
Window Air Conditioner or Spacer
Heater must have a plug with 3
prongs on it.
5. Plug the PSP300 straight into a 110 Volt electrical out-
let on the wall nearest your Air Conditioning Unit or
Space Heater.
6. Plug in the electrical cord from your Window Air
Conditioner or Space Heater directly into the front of the
PSP300.
COMPLETING YOUR INSTALLATION
7. Configure your thermostat at this time. Refer to
OPERATING INSTRUCTIONS.
8. Turn the ON/OFF switch on the upper right side to the
ON position.
9. Turn on your Air Conditioner or Space Heater and turn
the thermostat all the way up. (This will allow the
PSP300 to control the room temperature and maintain a
specific temperature)
10. Verify that the Window Air Conditioner or Space
Heater and its fan are operating properly. When set to a
high temperature, the heating system should provide
warm air after a short time. Likewise, a cooling system
should provide cool air after a short time. Usually sound
can be heard while they are running. The rush of mov-
ing air should be heard within a short time after either
has been started.
11. Your installation is now complete.
2. When you have the black ribbon out, simply push the
battery compartment back in while lining up the arrows.
3. On the back of the
PSP300, there is an
External Temperature
Sensor that looks like
an antenna. Pull this
sensor out of its clip
and bend the wire so
that it point straight up.
This is required for
accurate temperature
control.
4. On the upper right
side of the unit, there is
an On/Off switch.
Place this switch in the
OFF position for right
now.

RUN MODE
For the thermostat to function, the dial on the face of
the thermostat must be turned to the RUN position. If
you forget to do this, it will not work and the door will

Pressing these keys once will adjust a setting one
step in the associated direction.

ting will advance while holding one of these keys. Some
settings though, must be changed one press at a time.

®
approved program. There is
a 2-position slide switch to change temperature control
modes. Slide the switch to the mode you would like to
