Wall Montage
For the installation of the BSK Zephyr room type heat recovery device, first drill a hole on a wall facing the exterior with the dimensions indicated. To allow condensation water to flow outwards, the hole must be pierced outward with a slope of 1-2 degrees. After drilling, cut the outer pipe piece to protrude 10mm outside the wall and fix it using insulation materials or polyurethane foam.
-
The inner wall connection piece is placed on the 10mm part of the PVC pipe piece outside the wall and fixed with dowels.
-
The inner cover piece is mounted on the wall connection piece and fixed by screwing at the indicated places.
-
The capsule piece is aligned with the device hole and snapped into place with the ears facing the side and the ear with the fan socket facing left.
-
The front cover piece is seated by aligning it on the inner cover piece using its hinges. Ensure both hinges are in place.
-
The outer wall connection piece is placed to fit the 10mm part of the PVC pipe piece outside the wall and fixed with dowels.
-
The outer grille piece is aligned and seated over the outer wall connector. Ensure the tabs on the parts fit well.
Electrical Connection
For electrical connection, L and N lines of AC 220V/50Hz mains electricity connect to the terminal shown on the inner wall mounting part. Electrical cable connections can be hidden by routing them out of the wall through the cable hole, or by opening a hole on the side of the inner cover piece.
Wireless Pairing of Multiple Devices
BSK Zephyr devices can operate individually or as a group wirelessly. Connecting devices in multiple rooms allows control of other connected devices via a single master device. Up to 15 different address groups can be created.
Device Modes:
- Stand-alone Device Mode: The device operates independently. Address keys 3-4-5-6 are set to ON. Keys 1-2 do not matter.
- Primary Device Mode: Creates a wireless network for secondary devices with the same address to connect and be controlled. Key #1 is set to ON. The desired address is set using keys #3-4-5-6.
- Secondary Device - Reverse Mode: Operates in reverse to the primary device with the same address (e.g., primary blows air out, secondary takes air in). Keys #1 and #2 are set to OFF. Address keys 3-4-5-6 match the primary device.
- Secondary Device - Parallel Mode: Operates in parallel with the primary device with the same address (e.g., both blow air out). Key #1 is set to OFF and Key #2 is set to ON. Address keys 3-4-5-6 match the primary device.

IR Remote
On/Off Button
Pressing the On/Off button when the device is off opens the front cover and starts the fan. Pressing it when the device is on closes the front cover and stops the fan. ⏻
Air Flow Mode Buttons
These buttons control the direction of airflow.
- Supply mode: Supplies air from outside to inside continuously for 30 minutes. Returns to cycle mode afterward. No heat recovery in this mode. ? (Indicates air intake)
- Cycle mode: Default operating mode. Changes airflow direction every 70 seconds between supply and exhaust modes, recovering heat via the ceramic heat exchanger.
- Exhaust mode: Exhausts air from inside to outside continuously for 30 minutes. Returns to loop mode afterward. No heat recovery in this mode. ? (Indicates air exhaust)
Fan Speed buttons
These buttons adjust the fan speed.
- Night Mode: 15m³/h. Also closes the front cover further to reduce noise.
- Speed I: 30m³/h
- Speed II: 45m³/h
- Speed III: 60m³/h
Humidity Level buttons
These buttons adjust the set humidity value.
- Level I: 40%
- Level II: 60%
- Level III: 80%
The device uses a humidity sensor to control relative humidity. If the environment's humidity exceeds the set level, the device switches to a 'shot mode' for moisture evacuation. When humidity falls below the specified level, normal operation resumes.
Long-pressing the Level III button turns off automatic humidity mode, preventing the device from switching to humidity evacuation mode regardless of the humidity level.
