How to Prevent Mutual Interference of Multiple SRJ 3W Units: A Pairing Guide
Are you installing multiple SRJ 3W ventilation units in the same building or neighborhood at once? To ensure the system functions exactly as intended and the units do not interfere with each other, correct communication setup is crucial. In this article, we will explain why interference occurs and how to prevent it in a few simple steps.
Why does interference occur?
SRJ 3W units operate on a sensitive wireless signal at a frequency of 433 MHz. While this provides excellent range, it also means they can react to any nearby signal broadcasting on the same wavelength. If the units are not properly "locked" to a specific remote control, a single button press could inadvertently affect devices in other rooms or at a neighbor's property.
The Golden Rule: Pair Sequentially
Before proceeding with the technical setup, we have one essential piece of practical advice: recommend that clients pair their SRJ 3W units at different times. If installation is taking place in multiple apartments or rooms simultaneously, ensure that only one user completes the pairing process before the next one begins. This eliminates the risk of signals becoming "mixed" during the process.
Instructions: How to pair the SRJ 3W unit with a remote control
To resolve the interference issue, it is necessary to pair each SRJ 3W unit with its corresponding remote control.
Step-by-step procedure:
Preparation: Have the remote control designated for the specific device at hand. After pairing, please ensure that the remotes are not lost in the future.
Master Setting: Each SRJ 3W unit must be set as a "Master" unit. This activates its ability to communicate exclusively with the assigned remote.
Signal Locking: By performing the pairing sequence (see the procedure below), the communication will be locked. This reliably prevents mutual interference.

Correct configuration of the SRJ 3W unit during installation ensures trouble-free operation for end users and clean air without the need to address the accidental activation of neighboring devices.
