INTRODUCTION OVERVIEW

INSTALLATION INSTRUCTIONS

ELECTRICAL SHOCK HAZARD—Turn off power by unplugging the unit or by removing the fuse or switching the appropriate circuit breaker to the OFF position before removing the existing thermostat. Failure to do so could result in risk of electric shock.

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 and putty

TO REMOVE EXISTING THERMOSTAT

• Turn off power to heating and cooling system by removing the fuse or switching off the appropriate circuit breaker.
•  Remove cover of old thermostat. This should expose the wires.
•  Label the existing wires with the enclosed wire labels before removing wires.
• . After labeling wires, remove wires from wire terminals.
•  Remove existing thermostat base from wall.
•  Refer to the following section for instructions on how to install this thermostat.

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.
• Turn off power to the heating and cooling system by removing the fuse or switching off the appropriate circuit breaker.
• Move the Function switch on the thermostat to Off.
• Remove the cover by inserting and twisting a coin or screwdriver in the slots on the top of the thermostat.
• 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.
• With the base level, mark the placement of the mounting holes.
• Set thermostat base and cover away from working area
• Use a hammer to tap supplied anchors in mounting holes.
• Align thermostat base with mounting holes and feed the control wires through the wire opening.
• Seal hole for wires behind thermostat with nonflammable insulation or putty, or use a wall plate obtainable from a local hardware or home building store.
• Use supplied screws to mount thermostat base to wall.
• Insert stripped, labeled wires in matching wire terminals by pressing on the corresponding terminal contact. See the “Wiring Diagrams” section of this manual.
• Gently tug wire to be sure of proper connection.
• Double check that each wire is connected to the proper terminal.
• Replace cover on thermostat by snapping it in place.
• Plug the unit in or turn on power to the system at the main service panel.
• Test thermostat operation as described in the “Testing the Thermostat” section.

CONFIGURATION MODE

The configuration mode is used to set the RAK148F2 and RAK164F2 to match the heating/cooling system. These thermostats function with up to 2-stage heat pump systems (RAK148F2 only). To configure the RAK148F2 and RAK164F2, perform the following steps:

• Slide the Function switch to the OFF position.
• Remove the thermostat’s front cover.
• 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.)
• Once in the configuration mode, press the < or > button to change settings within each screen.
• Press the RIGHT button to advance to the next screen.
• Press the LEFT button to return to the previous screen.
• NOTE: To exit configuration mode at any time, slide the Function switch to Heat or Cool.

Configuration Mode Settings

• Temperature Scale (F or C)—Choose Fahrenheit or Celsius.
  • Press the < or > button to select.
  • Press the RIGHT button to advance to the next screen.
  • NOTE: Default factory setting is Fahrenheit.
• Temperature Differential—Stage 1— (1–9°F) (1–5°C)
  • Set the number of degrees between the “setpoint” temperature and the “turn on” temperature for first stage. Press the < or > button to set differential value.
  • Press the RIGHT button to advance to the next screen.
  • Note: Default factory setting is 2°F/1°C for each stage.
• Temperature Differential—Stage 2 (1–9°F/1–5°C) RAK148F2 only
  • Set the number of degrees between when stage 1 turns on and stage 2 turns on.
  • Press the button to set differential value.
  • Press the RIGHT button to advance to the next screen.
  • Note: Default factory setting is 2°F/1°C for each stage.
• Minimum Cool Setpoint (60, 64, 66, 68, 70, 72, 74, 76°F) (15, 17, 19, 20, 21, 22, 23, 24°C)

•  Off is also used to access Configuration mode.

Cool

•  In this mode, the thermostat controls the cooling system.
•  Press the < or > button to set the desired temperature.

Heat

•  In this mode, the thermostat controls the heating system.
•  Press the < or > button to set the desired temperature.

TESTING THE THERMOSTAT
Do not use air conditioning beyond the simple test when the outdoor temperature is below 50 degrees. This can damage the air conditioning system.

Note: Before testing the thermostat, move the Fan Auto/On switch to the Auto position.

Fan Test

•  With Function switch set to Off, slide
• Fan Speed switch to High, and slide
• Fan Auto/On switch to On position.
•  Indoor fan turns on in high speed.
•  Slide Fan Speed switch to Low.
•  Indoor fan slows to low speed.
•  Slide Fan Auto/On switch to Auto position.
•  Indoor fan turns off.

Cool Test

•  Slide Function switch to Cool position. Cool mode screen is displayed.
•  Adjust set temperature so it is 5 degrees below room temperature.
•  Air conditioning should come on within a few seconds.
•  Adjust the set temperature so it is 2 degrees above the room temperature and the A/C should turn off.
• 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 minimum run time/ off time delay).

Heat Test

•  Slide Function switch to Heat position. Heat mode screen is displayed.
• Adjust set temperature so it is 5 degrees above room temperature.
•  Heat should come on within a few seconds.
•  Adjust the set temperature so it is 2 degrees below the room temperature and the heat 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 minimum run time/ off time delay).

TROUBLESHOOTING

Problem	Solution
No Display	Check for 24 VAC; display is blank when 24 VAC is not present
System fan does not come on properly	Verify that wiring is correct.
All thermostat but- tons are inoperative	Verify that 24 VAC is present; unit will not operate when 24 VAC is not present.
Thermostat turns on and off too fre- quently	Adjust temperature differential (VHH &RQ¿JXUDWLRQ 0RGH – 6HWWLQJ Temperature Differential, Stage 1 and Stage 2 section).
Fan runs continu- ously	Check Fan Auto/On switch. If set to ON position, fan will run.
Room temperature is not correct	Verify that wall hole is plugged with SXWW\ RU LQVXODWLRQ WR SUHYHQW DLUÀRZ from the wall cavity. Adjust Tempera- WXUH 2IIVHW (VHH &RQ¿JXUDWLRQ 0RGH – Room temperature offset section).
Compressor doesn’t run or turn off im- mediately when changing function or setting	There is a 3 minute time delay and a 3 minute minimum run time for the compressor when it turns on/off.
Fan doesn’t run or turn off immedi- ately when changing function or setting	This is normal. On some models, the fan may have a minimum run time/off time delay.
Problem not listed above	Press the Reset button once to reset the thermostat and restore all factory settings.
