INSTALLATION  
TOOLS REQUIRED: Small regular screwdriver  
●
Read all instructions before using this ther-  
mostat.  
●
To reduce the risk of electric shock, this  
product has a grounding type plug that has a  
third (grounding) pin. This pin will only fit into a  
grounding type power outlet. If the plug does  
not fit into the outlet, contact a qualified electri-  
cian to install the proper outlet. Do not change  
the plug in any way.  
LOCATION:  
●
Do not locate where air circulation is poor,  
such as in a corner or an alcove; or behind an  
open door.  
●
Do not install it where there are unusual heat-  
ing conditions, such as: in direct sunlight; near a  
lamp, television, radiator, register, or fireplace;  
near hot water pipes in a wall; near a stove on  
the other side of the wall.  
●
Do not use Outdoors.  
●
Do not use in a bathroom. Never locate  
where it may fall into a bathtub or other water  
container.  
●
Do not locate in unusual cooling conditions,  
such as: on a wall separating an unheated  
room; or in a draft from a stairwell, door, or win-  
dow.  
●
Do not insert or allow foreign objects to enter

improperly. Be sure to follow all the Warnings  
and Cautions that came with the instruction  
manual written by the manufacturer of the  
Space Heater.  
PREPARING THE UNIT  
1. The PSP300 comes with (2) G13A size 1.5V  
Alkaline Button Cell Batteries already installed.  
These batteries power the clock only during nor-  
mal operation. They also provide backup power  
to retain the thermostats programs and settings  
while it is not plugged into the wall. In order to  
"activate" them, you must remove the black rib-  
bon from between the two batteries prior to  
using it. Use a small regular screwdriver to pry  
open the battery holder and pull out the black  
ribbon.  
●
Avoid the use of an extension cord because  
the extension cord may overheat and cause  
risk of fire. However, if you have to use an  
extension cord, the cord should be a 3-wire,  
grounding type, with No. 14 AWG minimum  
size and rated not less than 1875 Watts.  
●
Use this thermostat only as described in this  
manual. Any other use not recommended by  
the manufacturer may cause fire, electric  
shock, or injury to persons.  
●
Never clean this thermostat while it is  
plugged in. Turn On/Off switch to Off, pull out  
of the wall, and then clean by using a rag only.

2. Rotate the dial to SET DAY AND TIME.  
The abbreviation for the day of week will flash.  
W A R N I N G :  
●
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.

TEMPERATURE CONTROL MODES  
When a unit has first been powered up with the dial in  
the RUN position, your thermostat will begin to control  
your heating and/or air conditioning system according to  
it's default ENERGY STAR® approved program. There is  
a 2-position slide switch to change temperature control  
modes. Slide the switch to the mode you would like to  
use.  
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.

ADVANCED FEATURES  
CALIBRATION OFFSET  
TEMPERATURE VARIATION / SWING  
Your thermostat works by turning your heating or  
cooling system on and off whenever the room temper-  
ature varies a certain number of degrees from the set-  
point temperature. This variation is the "swing". Your  
system should cycle on about 3 to 6 times per hour. A  
smaller swing number increases the number of cycles,  
so room temperature is more constant. A larger swing  
number decreases the number of cycles, saving ener-  
gy in most cases.  
Your thermostat is accurately calibrated at the factory  
to within + 1°F. An offset value up to +5°F may be  
added to the temperature value that the thermostat  
measures. This may allow you to match this thermostat  
to another.  
To change this offset from its default value of 0:  
1. Open the door on the front of the thermostat.  
2. Rotate the dial to SET DAY/TIME.  
3. Simultaneously press NEXT and HOLD. The  
Temperature Offset value will flash.  
SWING ADJ USTMENT  
This setting controls when the heating or cooling  
turns on and off.  
●
The Swing setting sets the temperature variation the  
system allows above or below the set temperature  
before turning on the heating or Cooling. To change  
this value:  
1. Rotate the SPEED DIAL® to RUN.  
2. Press NEXT and HOLD simultaneously. The  
Temperature section of the display shows a single digit  
number between 1 and 9.  
4. The default value is 0 and in most cases should  
remain untouched.  
5. Use the UP/DOWN keys to adjust the offset value.  
6. Return the dial to its RUN position to accept the new  
value.
