Frequently Asked Questions - RT50W LEGRAND

How do I install the RT50W thermostat?

Turn off power at the breaker. Remove the old thermostat base. Connect wires according to the wiring diagram in the manual (typically L, N, and load). Mount the RT50W base, attach the faceplate, and restore power. If unsure, consult a qualified electrician.

Can I use the RT50W with a heat pump?

Yes, the RT50W is compatible with heat pumps as well as electric and gas systems. Set the system type in the installer menu.

How do I set the time and day?

Press the 'Menu' button, navigate to 'Clock' using arrow keys, then adjust hour, minute, and day. Confirm by pressing 'OK'.

What does the 'Frost Protection' mode do?

Frost Protection maintains a minimum temperature (usually 5°C/41°F) to prevent pipes from freezing when you're away. Activate it via the menu for energy savings.

How do I program daily heating schedules?

Access the 'Program' menu. You can set up to 4 time periods (Morning, Day, Evening, Night) with desired temperatures. Repeat for each day or copy a schedule.

The display is blank. What's wrong?

Check if power is supplied to the thermostat (circuit breaker on). If the display still blank, remove and reinsert the batteries (if using battery backup). If issue persists, the unit may be defective.

Can I lock the thermostat to prevent tampering?

Yes, enable Child Lock in the settings. You can set a PIN code to restrict access to menu and temperature changes.

What is the accuracy of the temperature sensor?

The RT50W has a ±0.5°C accuracy for precise temperature control, ensuring comfort and energy efficiency.

How do I reset the thermostat to factory defaults?

Press and hold the 'Menu' and 'Down' buttons simultaneously for 10 seconds. The display will indicate factory reset. Confirm to erase all custom settings.

USER MANUAL RT50W LEGRAND

The RT-50 is a time switch that turns OFF the connected light or fan when the selected time expires. The light behind the ON/OFF button illuminates while the switch is OFF. One of the time button indicators is always lit to indicate the last used timer.

Manual ON

Turn ON the connected light or fan by pressing the desired time button, or the ON/OFF button. If you press the ON/OFF button, it activates the timer that was last used.

Manual OFF

While a timer is active, you can press the ON/OFF button to turn OFF the connected light or fan without delay.

Changing the selected time

If you decide that you need more or less time than you originally selected, restart the time switch by pressing the button that matches the amount of time you think you'll need.

INSTALLATION

1. Prepare the switch box.

After the power is turned OFF at the circuit breaker box, remove the the old switch out from the wall box.

2. Identify the type of circuit.

In a Single Pole Circuit (see Fig. 1), two single wires connect to two screws on the existing switch. A ground wire may also be present and connected to a ground terminal on the old switch. A neutral wire should also be present in the wall box.

NOTE: If a proper ground is not available, consult with a qualified electrician before continuing installation.

Only connect the RT-50 to a Single Pole Circuit. The RT-50 is not suitable for 3-way switching. If the existing wiring does not match the description for a Single Pole Circuit, you should consult with a qualified electrician.

3. Prepare the Wires.

Tag the wires currently connected to the existing switch, so that they can be identified later. Disconnect the wires. Make sure the insulation is stripped off the wires to expose their copper cores to the length indicated by the "Strip Gage," in Fig. 2 (approximately 1/2 inch).

4. Wire the time switch.

Twist the existing wires together with the wire leads on the time switch as indicated in the drawing. Cap them securely using the wire nuts provided. See Fig 3 on the next page.

• Connect the green or non-insulated (copper) GROUND wire from the circuit to the GROUND terminal on the RT-50.
• Connect the power wire from the circuit (HOT) to the black wire on the RT-50.
• Connect the power wire to the lamp or fan (LOAD) to the red wire on the RT-50.

• Connect the NEUTRAL wires from the circuit to the white wire on the RT-50.

• Put the RT-50 in the wall box with the time selection buttons positioned above the ON/OFF button.

Secure it to the wall box with the screws provided.

6. Install cover plates.

Install industry standard decorator wall switch cover plate (not included).

WARNING: TURN THE POWER OFF AT THE CIRCUIT BREAKER BEFORE WIRING.

GROUND TO THE TIME SWITCH PROVIDES

PROTECTION AGAINST ELECTRICAL SHOCK

IN THE EVENT OF CERTAIN FAULT CONDITIONS.

7. Restore power to the circuit.

Turn on the breaker or replace the fuse.

Twist the existing wires together with the wire leads on the time switch as indicated in the drawing. Cap them securely using the wire nuts provided. See Fig 3.

• Connect the green or non-insulated (copper) GROUND wire from the circuit to the GROUND terminal on the RT-50.
• Connect the power wire from the circuit (HOT) to the black wire on the RT-50.
• Connect the power wire to the lamp or fan (LOAD) to the red wire on the RT-50.
• Connect the NEUTRAL wires from the circuit to the white wire on the RT-50.

8. Put the RT-50 in the wall box with the time selection buttons positioned above the ON/OFF button.

Secure it to the wall box with the screws provided.

9. Install cover plates.

Install industry standard decorator wall switch cover plate (not included).

10. Restore power to the circuit.

Turn on the breaker or replace the fuse.

TROUBLESHOOTING

To test the time switch:

The light behind the ON/OFF button should be ON when the switch is OFF. The indicator light on one of the time selection buttons is ON.

Press the ON/OFF button. The connected light or fan comes ON. The connected light or fan should turn OFF in the number of minutes indicated by the time selection indicator light. You can turn it OFF sooner by pressing the ON/OFF button again.

Light or fan will not turn ON (lighted switch is ON):

Press ON/OFF button. The connected light or fan should turn ON. If not:

• Check the light bulb and/or motor switch on the fan mechanism.
• Turn OFF power to the circuit, then check wire connections.

Light or fan will not turn ON (lighted switch is OFF and no indicator is ON):

• Shade the switch from external light to make sure that none of the indicator lights are ON.
• Check the light bulb and/or motor switch on the fan mechanism.
• Make certain that the circuit breaker is ON and functioning.
• Turn OFF power to the circuit then check wire connections.
  • Call 1.888.817.0571 for technical support.

Light or fan will not turn OFF:

- Press the ON/OFF button.
