The KLI 310 wall remote communicates with Velux Integra devices via the io-homecontrol radio protocol. When the connection between the remote and the roller shutter motor is lost, the shutter no longer responds to commands. The reset process involves deleting the existing pairing and then restoring the radio communication between the two devices.
io-homecontrol Protocol and Pairing of the KLI 310
The io-homecontrol protocol uses a security key exchange between the transmitter (the remote) and the receiver (the motor of the shutter). Each Integra product stores the key of the remote that controls it. If this key is corrupted or lost (after a battery change, a prolonged power outage, or accidental handling), the motor ignores the received commands.

The KLI 310 is not a standard portable remote: it is a wired wall keypad designed to be mounted on a wall or window frame. Its programming button, accessible at the back or under the cover depending on the version, triggers the pairing sequence. Before attempting a reset, it is essential to ensure that the issue is indeed with the radio link and not with a mechanically jammed motor.
To better understand how to reset the Velux roller shutter remote as a whole, the distinction between resetting the remote and resetting the motor is the first point to clarify.

Difference Between Remote Reset and Velux Integra Motor Reset
The confusion between these two operations causes the majority of reset failures. They are two distinct procedures, sometimes necessary one after the other.
Resetting the KLI 310 Remote
This operation clears the products stored in the remote’s memory. After a reset, the KLI 310 no longer controls any equipment. It is then necessary to restart the pairing process with each affected shutter or blind.
The typical sequence involves removing the back cover, locating the “Prog” or “Reset” button, and then holding it down with a thin object (paperclip, pen tip) until the LED on the remote blinks in a specific way. A rapid blink indicates programming mode, while a slow blink confirms that the memory has been cleared.
Resetting the Roller Shutter Motor
The Integra motor has its own pairing memory. If the motor no longer recognizes any remote, cutting the power supply to the shutter for several seconds allows it to return to receptive mode. On solar shutters, the battery must be disconnected and then reconnected.
After resetting the motor, it enters a short radio listening window. The remote must be set to pairing mode during this window for the two devices to exchange a new security key.
Complete Reset Procedure for Velux KLI 310 Roller Shutter
This procedure applies when neither the remote nor the motor communicates. It combines the two resets described above in a specific order.
- Cut the power to the roller shutter motor at the circuit breaker (electric shutter) or disconnect the battery (solar shutter). Wait about fifteen seconds before restoring power.
- On the KLI 310, remove the back cover and hold the programming button until the LED blinks slowly, confirming that the memory has been cleared.
- Restore power to the motor. In the following seconds, briefly press the “Prog” button on the remote to initiate pairing.
- Test the shutter by pressing the up and down buttons. If the shutter responds, the pairing is successful. If not, repeat the sequence while respecting the power cut timing.
Timing between restoring power to the motor and activating pairing mode on the remote is the critical point. A delay that is too long causes the motor to exit its radio listening window, and the pairing fails silently.
KLI 311, 312, and 313 Variants: Check Compatibility Before Manipulating
Velux offers the KLI range in several references. The KLI 311, KLI 312, and KLI 313 each control a different type of equipment (window, interior blind, exterior shutter). The reset procedure remains similar in its main lines, but the radio channels and associated product groups differ by reference.
Attempting to pair a KLI 312 (dedicated to blinds) with an exterior roller shutter motor will not work, even if the physical manipulation seems identical. Before any reset, turn the remote over and check the exact reference printed on the label.
The Velux Academy documentation details the possible associations between remotes and Integra products. It also specifies how to group multiple products on the same wall keypad, a useful function when the same attic houses a motorized window, a blackout blind, and a roller shutter.
Troubleshooting When KLI 310 Reset Fails
If the shutter still does not respond after two attempts of the complete procedure, several avenues deserve exploration.
- Check the condition of the remote batteries. Weak batteries emit a radio signal that is too weak to reach the motor, especially if the distance exceeds a few meters.
- Ensure that the circuit breaker is supplying power to the motor. A tripped breaker upstream can sometimes go unnoticed in a crowded electrical panel.
- Listen to the motor at the moment of power restoration: a slight mechanical noise (brief humming) confirms that the motor is receiving power and resetting. In the absence of any sound, the problem is electrical and not radio.
- Check that no other remote or control box (such as KLC 500) has taken control of the product. An Integra device already paired with another transmitter may refuse a new pairing until the old one is deleted.
The case of a mechanically jammed motor (shutter stuck due to frost, warped slat, seized axle) cannot be resolved by a radio reset. If the motor emits a continuous humming sound without any movement of the curtain, physical intervention on the shutter is necessary before any reprogramming.
Resetting the KLI 310 remains an operation accessible without specialized tools, provided that the order of steps and the timing of the motor’s listening window are respected. When the problem persists despite several proper attempts, the fault rarely lies with the remote.
