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. Move the Function switch on the thermostat to Off.
3. Remove the cover by inserting and twisting a coin or
screwdriver in the slots on the top of the thermostat.
4. 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.
5. With the base level, mark the placement of the
mounting holes.
6. Set thermostat base and cover away from working area.
7. Using a 3/16s drill bit, drill holes in the locations you
have marked for mounting.
8. Use a hammer to tap supplied anchors in mounting holes.
9. Align thermostat base with mounting holes and feed
the control wires through the wire opening.
10. 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.
11. Use supplied screws to mount thermostat base to wall.
12. Insert stripped, labeled wires in matching wire terminals
by pressing on the corresponding terminal contact. See
the “Wiring Diagrams” section of this manual.
CAUTION! Make sure exposed portion
of wires does not touch other wires.
13. Gently tug wire to be sure of proper connection.
Double check that each wire is connected to the
proper terminal.

Configuration mode.
The configuration mode is used to set the RAK148D2 and RAK164D2
to match the heating/cooling system. These thermostats function
with up to 2-stage heat pump systems (RAK148D2 only).
To configure the RAK148D2 and RAK164D2, 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 thermostat’s front cover.
3. To enter the configuration mode, simultaneously hold
the LEFT and RIGHT buttons in for 6 seconds while the
thermostat is in OFF mode. (See diagram on page 3.)
