IMPORTANT!
Please read all instructions carefully before beginning installation
and save for future reference. Before removing any wiring from
your existing thermostat, its wires must be labeled with their
terminal designations. Ignore the color of the wires since they
may not comply with any standard.
Thank you for your confidence in our product. To obtain the best results
from your investment, please read this manual and acquaint yourself with
your purchase before installing your new thermostat. Then follow the
installation procedures, one step at a time. This will save you time and
minimize the chance of damaging the thermostat and the systems it
controls. These instructions may contain information beyond that required
for your particular installation. Please save for future reference.

●
In the winter, set the system switch to HEAT to control your heating
system.
●
In the summer, set the switch to COOL to control your air conditioner.
●
Press either the TEMPERATURE UP or DOWN key in order to show
the current SET TEMPERATURE.
●
Press TEMPERATURE UP or DOWN keys again until your desired
temperature is displayed. The display will show the current room
temperature again after two seconds.
●
Press the light bulb button to illuminate the display. Adjusting the
temperature will keep the display lit until no button has been pressed
for over ten seconds.
●
In spring and fall or when windows are open, you can set the system
switch to OFF.
●
Setting the FAN switch to AUTO automatically runs your system’s fan
during heating and cooling.
●
Setting the FAN switch to ON runs your system’s fan continuously even
without heating or cooling.
●
Setting the Mode switch to EMER (emergency heat) runs your
Emergency heating system rather than the heat pump.
INSTALLATION
Please read all instructions carefully before beginning installation.
CAUTION
Turn off electricity to the appliance before installing or
servicing thermostat or any part of the system. Do not
turn electricity back on until work is completed.
●
Do not short (jumper) across electric terminals at control on furnace or
air conditioner to test the system. This will damage the thermostat and
void your warranty.
●
All wiring must conform to local codes and ordinances.
●
This thermostat is designed for use with 24 volt and millivolt systems.
The thermostat should be limited to a maximum of 1.5 amps; higher
current may cause damage to the thermostat. If you are in doubt, call
your HVAC contractor.
●
Your thermostat is a precision instrument. Please handle it with care.

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.
●
Remember that your PSDH121 may be mounted vertically or
horizontally when determining the optimal location.
●
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, radio, 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 will
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.

DIGITAL ELECTRONIC HEAT PUMP THERMOSTAT

NOTE
If you are mounting the base to a soft material like
plasterboard or if you are using the old mounting holes, the
screws may not hold. Drill a 3/16-in. (4.8mm) hole at each
screw location, and insert the plastic anchors provided. Then
mount the base as described below.

BASE
TAB
5. Route the wires through the large hole in the base
plate by the terminal block. Hold the base against
the wall, with the wires coming through. Position the
base for best appearance (to hide any marks from an
old thermostat). The terminal block should be either
to the right of or below the routing hole. Attach the
base to the wall with the two screws provided.
CAUTION
Read instructions carefully before removing any wiring from existing
thermostat. Wires must be labeled before they are removed. When
removing wires from their terminals, ignore the color of the wires
since they may not comply with any standard.
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. Label and remove 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 PSDH121 ON THE WALL
1. Decide whether the thermostat will be mounted vertically or horizontally.

CAUTION
Be careful not to drop the unit or disturb any electronic parts.
2. Strip insulation 3/8 in. (9.5mm) from
wire ends and clean off any corrosion.
3. Fill wall opening with non-combustible
insulation to prevent drafts from affecting
the thermostat.
4. Cup the thermostat with one hand behind the thermostats display.
Separate the unit from it’s base plate using the tabs protruding from it’s
body with the other hand.

INSTALLATION OPTIONS
There are four options which are set by a group of numbered jumpers
on the rear of the units circuit board. They are:
J1: The minimum run time jumper J1 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.
J2: The temperature format: jumper selects whether your thermostat
displays temperatures in Celsius or Fahrenheit.
J3: This Jumper determines whether the display will be horizontally or
vertically oriented.
J4: This Jumper controls the “swing” or temperature variation in the
home. Using the smaller number results in more stable temperature, while
the wider setting is provided as a more energy efficient alternative. Users
of force hot water systems may find the 0.25 setting more comfortable.

The Installation is now complete.
The table above is printed on the circuit board. To change the jumper
position, pull it straight off the pins it covers. Replace the jumper over one
or both pins as determined by your desired setting. To prevent its loss, a
jumper may be placed over one pin only for the open positions. After
settings have been changed, press the small unmarked RESET button on
the front of the thermostat for the changes to take effect.

INSTALL BATTERIES
For detailed instruction, see BATTERIES/MAINTENANCE to install
batteries at this time.
●
Turn the power back on to your heating and/or air conditioning system.
●
Verify that the system and it’s 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 from the furnace and air conditioning units can be
heard while they are running. The rush of moving air should be heard
within a short time after either has been started.
BATTERIES/MAINTENANCE
1. Remove fresh batteries from their carton.
2. Remove body of thermostat as described during installation.
3. Remove the used batteries if present.
4. Install two new Energizer®or DURACELL®"AA" size alkaline batteries in
the battery compartment. Observe the polarity marking shown in the
compartment.
5. Place the body back on the wall.
6. Using a small Phillips screwdriver press the RESET button which is
between the Up/Down arrow button. Within 90 seconds the thermostat
will begin to display the room temperature.
BATTERY COMPARTMENT
NOTE
REPLACE BATTERIES WHEN “LOBAT” APPEARS IN THE DISPLAY
OR AT LEAST ONCE A YEAR.
