Frequently Asked Questions - RAK150VF2 GE

How to install the RAK150VF2 thermostat?

First, turn off power at the circuit breaker. Remove the old thermostat, labeling the wires. Mount the new thermostat base at 1.5 m above the floor, using wall anchors and screws. Route the wires through the opening, connect them to the corresponding terminals according to the wiring diagram, then replace the cover and restore power.

How to configure the thermostat for my system?

Make sure the thermostat is in OFF position. Remove the cover, press CONFIG for about 2 seconds to enter configuration mode. Use + and - buttons to change settings, FAN to advance to the next screen, and MODE to go back. Settings include temperature scale, temperature differentials, system type (HP b2, HP b1, ELC), temperature limits, etc. Press CONFIG again to save and exit.

Why is the display not turning on?

Check that the power supply voltage is 24 V AC. Without this voltage, the display will not operate. Also ensure the circuit breaker is on and connections are correct.

The compressor does not start or turns off immediately, what to do?

The thermostat imposes a 3-minute delay when starting and stopping the compressor. Wait this delay before considering a problem. If the issue persists, check the wiring and system configuration.

How to adjust the temperature differential to avoid too frequent cycling?

Access configuration mode (CONFIG for 2 sec). Use + and - buttons to change the temperature differential for stage 1 (default 1 °F / 0.5 °C) and stage 2 (if applicable). A larger differential reduces cycling frequency.

The fan does not stop, what to check?

Check the fan Auto/On switch. If it is in ON position, the fan runs continuously. Press the FAN button to switch to Auto mode. In configuration mode, step 9 allows disabling the continuous fan option.

How to calibrate the displayed room temperature?

In configuration mode, step 8 allows adjusting a room temperature offset from +9 °F to -9 °F (+5 °C to -5 °C). Adjust this value until the display matches the actual temperature measured with a reliable thermometer.

What tools are needed for installation?

You will need a drill with a 5 mm (3/16 inch) bit, a hammer, a screwdriver, and putty or insulation to seal the hole in the wall behind the thermostat.

What to do if the thermostat does not respond to any button?

Ensure the power supply voltage is 24 V AC. If the display is off or frozen, press the Reset button (if present) once to reset the microprocessor. If the problem persists, check the wiring.

The thermostat displays an incorrect temperature, what to do?

First, check that the hole in the wall is properly sealed with putty or insulation to prevent drafts. Then, adjust the room temperature offset in configuration mode (step 8) to calibrate the display.

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.

1. Turn off power to the heating and cooling system by removing the fuse or switching off the appropriate circuit breaker.
2. Remove the cover by inserting and twisting a coin or screwdriver in the slots on the top 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. With the base level, 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.

TO INSTALL THERMOSTAT (cont.)

1. 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.
2. Use supplied screws to mount thermostat base to wall.
3. Insert stripped, labeled wires in matching wire terminals by pressing on the corresponding terminal contact. See the "Wiring Diagrams" section of this manual.

NOTICE

Make sure exposed portion of wires do not touch other wires.

1. Gently tug wire to be sure of proper connection. Double check that each wire is connected to the proper terminal.
2. Replace cover on thermostat by snapping it in place.
3. Plug the unit in or turn on power to the system at the main service panel.
4. Test thermostat operation.

TROUBLESHOOTING TIPS

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 buttons are inoperative	Verify that 24 VAC is present; unit will not operate when 24 VAC is not present.
Thermostat turns on and off too frequently	Adjust temperature differential (see Configuration Mode - Setting Temperature Differential, Stage 1, Stage 2, and Stage 3 section).
Fan runs continuously	Check fan selection. If set to ON, fan will run.
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 immediately 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 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 microprocessor.
