INSTALLATION INSTRUCTIONS
TO INSTALL THERMOSTAT
IMPORTANT: Thermostat installation must conform to
local and national building and electrical codes and ordinances.
Note: Mount the thermostat about five feet above the floor.
Do not mount the thermostat on an outside wall, in direct
sunlight, behind a door or in an area affected by a vent or duct.
ELECTRICAL SHOCK HAZARD—Turn off power at
the main service panel by removing the fuse or
switching the appropriate circuit breaker to the OFF
position before removing the existing thermostat.
TO REMOVE EXISTING THERMOSTAT
1. Turn off power to heating and cooling system by removing
the fuse or switching off the appropriate circuit breaker.
2. Remove cover of old thermostat. This should expose the wires.
3. Label the existing wires with the enclosed wire labels
before removing wires.
4. After labeling wires, remove wires from wire terminals.
5. Remove existing thermostat base from wall.
6. Refer to the following section for instructions on how
to install this thermostat.
PACKAGE CONTENTS/TOOLS REQUIRED
Package includes: Thermostat on base, thermostat cover,
wiring labels, screws and wall anchors.
Tools needed: Drill with 3/16″bit, hammer, screwdriver.

TO INSTALL THERMOSTAT (cont.)
1. Turn off power to the heating and cooling system
by removing the fuse or switching off the appropriate
circuit breaker.
2. To remove cover, insert and twist a coin or screwdriver
in the slots on the sides of the thermostat.
3. Put thermostat base against the wall where you plan
to mount it. Make sure wires will feed through the wire
opening in the base of the thermostat.
4. Mark the placement of the mounting holes.
5. Set thermostat base and cover away from working area.
6. Using a 3/16″drill bit, drill holes in the locations you
have marked for mounting.
7. Use a hammer to tap supplied anchors in mounting
holes.
8. Align thermostat base with mounting holes and feed
the control wires through the wire opening.
9. Use supplied screws to mount thermostat base to wall.
10. Insert stripped, labeled wires in matching wire
terminals. See “Wiring Diagrams” section of this
manual.
CAUTION! Make sure exposed portion
of wires does not touch other wires.
11. Tighten screws on terminal block. Gently tug wire to
be sure of proper connection. Double check that each
wire is connected to the proper terminal.
12. Seal hole for wires behind thermostat with non-flammable
insulation or putty, or use a wall plate obtainable from
a local hardware or home building store.

Configuration mode.
The configuration mode is used to set the RAK148D1 and RAK164D1
to match your heating/cooling system. These thermostats function
with up to 2-stage heat pump systems (RAK148D1 only).
To configure the RAK148D1 and RAK164D1, perform the
following steps:
Note: Operation being set will blink in the display.
1. Slide the Function switch to the OFF position.
2. Remove the cover of the thermostat by gently pulling
on one of the corners.
3. Simultaneously hold the SW5 and SW6 buttons in
for 5 seconds while the thermostat is in OFF mode.
4. Press the or button to change settings within
each screen.
5. Press the SW6 button to advance to the next screen.
Note: The SW5 button will return you to the previous screen.
6. To exit configuration mode, slide the Function switch to Heat
or Cool.
Configuration Mode Settings
The setup screens for Configuration Mode are as follows:

Choose Fahrenheit or Celsius.
Press the or button
to select.
Press the SW6 button to advance to the next screen.
2. Temperature Differential—
Stage 1—(1–9°F) (1–5°C)—
(Factory Setting is 2°F/1°C for
Each Stage)—Set the number of
degrees between your “setpoint” temperature and your
“turn on” temperature for first stage.
Press the or button to set differential value.
Press the SW6 button to advance to the next screen.

Starting the thermostat.
CAUTION! Do not use air conditioning when
the outdoor temperature is below 50 degrees. This can damage
your air conditioning system and cause personal injuries.
1. Move the Fan Auto/On switch
to the Auto position.

Testing the thermostat.
Once the thermostat is installed, it should be thoroughly tested.
CAUTION! Do not use air conditioning when
the outdoor temperature is below 50 degrees. This can damage
your air conditioning system and cause personal injuries.
Cool Test
1. Slide Function switch to Cool mode.
2. Adjust set temperature so it is 5
degrees below room temperature.
3. Air conditioning should come on within a few seconds.
4. Adjust the set temperature so it is 2 degrees above the room
temperature and the A/C should turn off. Note: There is a 3
minute time delay and a 3 minute minimum run time for the
compressor when it turns on/off. (On some models, the fan
may also have a 3 minute minimum run time/off time delay).

Heat Test
1. Slide Function switch to Heat mode.
2. Adjust set temperature so it is 5
degrees above room temperature.
3. Heat should come on within a few seconds.

minute time delay and a 3 minute minimum run time for the
compressor when it turns on/off. (On some models, the fan
may also have a 3 minute minimum run time/off time delay).
Note: “Quick Heat Recovery” is activated each time the thermostat
is switched from Off or Cool modes to Heat mode. Electric heaters
