  4. Put the 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 the working area.
  7. Using a 3/16″ drill bit, drill holes in the locations you have marked for mounting. 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 holes for wires behind the thermostat with non-flammable insulation or putty, or use a wall plate obtainable from local hardware or home building store.
  11. Use supplied screws to mount the thermostat base to the 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.NOTICEMake sure the exposed portion of wires does not touch other wires.
  13. Gently tug wire to be sure of the proper connection. Double-check that each wire is connected to the proper terminal.
  14. Replace the cover on the thermostat by snapping it in place.
  15. Plug the unit in or turn on the power to the system at the main service panel.
  16. Test thermostat operation as described in the “Testing the Thermostat” section.

CONFIGURATION MODE

The configuration mode is used to set the RAK149F2 to match the PTAC’s heating/cooling system. The default setting of this thermostat is for 1-stage cooling with a 2-stage heat pump system. To configure for a 1-stage cooling with a 1-stage heating,see #2 in the Configuration Mode Settings below. To configure the RAK149F2, perform the following steps:

Note: The 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 theLEFT and RIGHT buttons in for 3 seconds while the thermostat is in OFF mode. (See diagram on page 3.)
  4. 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

The setup screens for Configuration Mode are as follows:

  1. 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.
  2. Heat System—Check the model number on the GE PTAC chassis to determine the primary heating method.AZ65H/95H***** are heat pumps and are the thermostat factory setting.AZ45E/95E***** are electric heat models and will require a mode setting change.To change the heating mode configuration, press the RIGHT button to advance to the HSH screen.

  • 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

Once the thermostat is installed, it should be thoroughly tested.

NOTICEDo 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

  1. With Function switch set to Off, slideFan Speed switch to High, and slideFan Auto/On switch to On position. Low High
  2. Indoor fan turns on at high speed.
  3. Slide Fan Speed switch to Low.
  4. Indoor fan slows to low speed.
  5. Slide Fan Auto/On switch to Auto position.
  6. Indoor fan turns off.

Cool Test

  1. Slide Function switch to Cool position. Cool mode screen is displayed.
  2. Adjust the 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 minimum run time/ off time delay).

Heat Test

  1. Slide Function switch to Heat position. Heat mode screen is displayed.
  2. Adjust the set temperature so it is 5 degrees above room temperature.
  3. Resistance heat should come on within a few seconds.
  4. 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 TIPS

Problem

Solution
No Display Check for 24 VAC; the display is blank when 24 VAC is not present
The system fan does not come on properly Verify that the wiring is correct.
All thermostat buttons are inoperative Verify that 24 VAC is present; the unit will not operate when 24 VAC is not present.
The thermostat turns on and off too frequently Adjust temperature differential

(see Configuration Mode – Setting Temperature Differential, Stage 1 and Stage 2 section).
Fan runs continuously Check Fan Auto/On switch. If set to ON position, fan will run.
The room temperature is not correct Verify that wall hole is plugged with putty or insulation to prevent airflow from the wall cavity. Adjust Tempera­ture Offset (see Configuration Mode – 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.
The fan doesn’t run or turn off immediately 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.
