RZ050 Air Conditioner Motion Sensor Controller

RZ050-V4

$27.00

The RZ050 is a battery-powered air conditioner motion sensor controller for compatible infrared-controlled split ACs. As an AC occupancy sensor, it uses PIR motion detection to send a learned, discrete IR OFF command after your selected no-motion delay, helping reduce cooling in empty rooms. Night Mode suppresses automatic OFF below 1 lux.

Choose a 15-minute, 30-minute, 1-hour (default), or 2-hour no-motion delay. Automatic shutoff requires a learned, discrete OFF command; optional room-entry ON requires a separate learned ON command. RZ050 can also learn temperature commands instead of power commands, while the AC regulates room temperature. Night Mode suppresses automatic OFF below 1 lux. Two AAA batteries and adhesive or screw mounting let you install RZ050 without changing the AC wiring.

Occupancy Sensor Control for Air Conditioners

Use RZ050 as an occupancy sensor for your air conditioner to reduce cooling left running in empty rooms. Its PIR sensor detects motion; after your selected no-motion delay, RZ050 sends a learned, discrete infrared OFF command to a compatible split AC.

This automatic AC shutoff responds to a lack of detected motion, not proof that the room is empty. Night Mode suppresses automatic OFF when ambient light is below 1 lux.

Door and Window AC Control with RZ050-DS

Need a door sensor to turn off the air conditioner when a door or window is left open? Choose the RZ050-DS controller with compatible door and window contact sensors.

Standard RZ050 uses its own PIR motion sensor and does not connect to external contact sensors. See the RZ050-DS door and window AC controller for this application.

Reduce Cooling Without Turning the AC Off

RZ050 can learn temperature commands from a compatible AC remote for temperature setback instead of shutoff. For example, send a 21°C setting on entry and a 28°C setting after the selected no-motion delay to keep cooling available at a higher setpoint.

These temperatures are examples. RZ050 sends the learned IR commands; the air conditioner measures and regulates room temperature.

RZ050 AC Motion Sensor Features and Specifications

RZ050 Control Features

  • PIR occupancy control and IR learning: RZ050 detects motion and controls compatible infrared split ACs with learned remote commands. Automatic OFF needs a discrete OFF command; optional room-entry ON needs a separate learned ON command.
  • Adjustable no-motion delay: RZ050 sends its learned away command after 15 minutes, 30 minutes, 1 hour (default), or 2 hours without detected motion.
  • Night Mode: RZ050 suppresses automatic AC OFF below 1 lux. Motion-triggered ON remains available when a suitable ON command has been learned.
  • Battery-powered installation: RZ050 uses two AAA batteries and mounts with adhesive or screws, with no AC rewiring.
  • Learned temperature commands: RZ050 can send startup and temperature setback settings instead of power commands; the AC regulates room temperature.
  • Status indicators: Five red flashes indicate low battery. The PIR motion detection indicator can be switched on or off.

RZ050 AC Motion Sensor FAQs

Will RZ050 work with my AC or HVAC system?

RZ050 works with compatible infrared-controlled split ACs. If you are looking for an AC motion sensor switch or HVAC occupancy sensor, check the control method: RZ050 sends learned IR commands, without switching mains power or controlling every type of HVAC system. Automatic shutoff requires a discrete OFF code; optional turn-on requires a separate ON code. A single power-toggle code is not supported.

How do I install RZ050 without rewiring the AC?

Insert two AAA batteries, teach RZ050 the required commands from your compatible AC remote, and mount it with adhesive or screws. Position it so the PIR sensor can detect room movement and its IR signal can reach the AC receiver. No AC rewiring is required.

How long do the RZ050 batteries last?

RZ050 uses two AAA batteries, with an expected life of at least one year under normal use, according to the product specification. Five red flashes indicate low battery.

Will RZ050 turn off the AC while I sleep?

RZ050 Night Mode suppresses automatic OFF when ambient light is below 1 lux. This is a light-based operating condition, not continuous detection of a sleeping person. Optional motion-triggered ON remains active when a suitable separate ON command has been learned.

Can RZ050 turn the AC on automatically?

Yes. After the no-motion delay has completed, RZ050 can send a learned ON command when motion is detected again, provided the compatible remote supplies a separate ON code. Relearning the OFF command clears the saved ON command.

Why won’t the AC restart after I turn it off manually?

RZ050 receives no AC status feedback. If you manually switch off the AC while staying in the room, detected movement only resets its delay. Automatic turn-on becomes available again after RZ050 completes the no-motion delay and sends OFF. You can also restart the AC manually with its remote.

Can I use door and window sensors with RZ050?

Standard RZ050 does not connect to external door or window contact sensors. If you need a door sensor to turn off the air conditioner when a door or window is left open, choose the RZ050-DS door and window AC controller with compatible contact sensors.

Can RZ050 change the temperature instead of switching the AC off?

Yes. RZ050 can learn temperature commands from a compatible remote and send a higher cooling setpoint after the selected no-motion delay. It sends the learned setting; the AC measures and regulates room temperature. RZ050 is not a temperature sensor or a continuously regulating thermostat.

Can RZ050 be used as an AC presence sensor?

RZ050 supports occupancy-based AC control through PIR motion detection. If you are comparing air conditioning presence sensors, it may not detect someone who remains still. Choose a suitable delay for seated work; Night Mode suppresses automatic OFF below 1 lux, rather than continuously detecting a sleeping person.

What warranty and support are available for RZ050?

RZ050 comes with a one-year limited warranty. Watch the RZ050 setup and AC compatibility videos below, or contact [email protected] for setup help, compatibility questions, or the user manual.
