THERMOSTAT LOCATION
On replacement installations, mount the new thermostat in place of the
old one unless the conditions listed below suggest otherwise. On new
installations, follow the guidelines listed below.
●
Locate the thermostat on an inside wall, about 5 ft. (1.5m) above the floor,
and in a room that is used often.
●
Do not install it where there are unusual heating 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 a wall.
●
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 window.
●
Do not locate in a damp area. This can lead to corrosion that may shorten
thermostat life.
●
Do not locate where air circulation is poor, such as: in a corner or an
alcove; or behind an open door.
●
Do not install the unit until all construction work and painting has been
completed.
CAUTION
The PSP511A/PSP511LA is protected against normal static electric discharges. To
minimize the risk of damaging the unit in extremely dry weather, touch a grounded
metal object before touching your thermostat.
REMOVING THE OLD THERMOSTAT
1. Switch electricity to the furnace and air conditioner
OFF; then proceed with the following steps.
2. Remove cover from old thermostat. Most are snap-on
types and simply pull off. Some have locking screws on
the side. These must be loosened.
3. Note the letters printed near the terminals. Attach
labels (enclosed) to each wire for identification. Remove
and label wires one at a time. Make sure the wires do not
fall back inside the wall.
4. Loosen all screws on the old thermostat and remove it from the wall.
MOUNTING THE PSP511A/PSP511LA
5. Strip insulation leaving 3/8 in. (9.5mm) bare
wire ends and clean off any corrosion.
6. Fill wall opening with non-combustible insu-
lation to prevent drafts from affecting the ther-
mostat.

ADVANCED FEATURES
TEMPERATURE SWING
A thermostat works by turning your heating or cooling system on or off whenever the
room temperature varies 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, but saves energy in most cases.
SWING SETTING
1. With the Dial in its RUN position, simultaneously press NEXT & HOLD.
2. Use the UP and DOWN keys to change swing.
3. Choices are 1 through 9. The default is 1.
4. Rotate the dial to the RUN position or press NEXT to finish.
JUMPER SETTINGS
There are three jumpers and one switch. Each controls a setting corresponding to its
position.
5MIN/2MIN MINIMUM RUN TIME - JP3
The position of J3 sets the minimum length of time that the thermostat must remain
with Heat or Cool either on or off before it will automatically switch to the alternate On or
Off state. This feature prevents short cycling and provides compressor protection for
cooling units. Choices are 2 or 5 minutes.
TEMPERATURE DISPLAY FORMAT °F/C - JP2
The position of this jumper controls whether temperature is displayed in degrees F° or C°
TIME DISPLAY FORMAT 12/24 HR CLOCK - JP1
The position of this jumper controls whether time is displayed in 12 hour or 24 hour
Military Time format.
REPOSITIONING JUMPERS
To change a setting, the jumper must be repositioned and a HARDWARE RESET must
be performed. Note that as long as you press the Hardware Reset button (inside) and not
the Software Reset button (front), you will change settings and not lose your
program.These jumpers are located inside the thermostat on the rear of its circuit board.
To access them, remove the unit from the wall by pressing up on the thumb latch at the
bottom of thermostat and swinging the body out and away.
GAS/ELECTRIC SWITCH
This switch controls whether the thermostat requests the system fan to run when it is
in HEAT mode with the fan set to AUTO. Then with the switch set to GAS the fan is con-
trolled by the heating system itself and the terminal will remain inactive. With the gas
switch set to Electric (ELEC), the fan is controlled by the thermostat.
