Installation

Preparation

Thorough planning is strongly recommended before commencing installation to achieve the best possible ventilation solution. A planning checklist is provided:

• Sensors (Refer to Page 9)
• Ceiling Controller (Refer to Page 11)
• Touch Screen Controller (Refer to Page 12)

Sensors

Important: DO NOT mount sensors before reading all instructions.

Locations:

• DO NOT install sensors within one meter of diffusers.
• DO NOT install sensors close to localized sources of heat, draughts, moisture, or odours.
• Install the outside sensor on the south side of the house, shielded from rain and strong wind, close to the supply grille (typically under the soffit).
• Install the roof sensor close to the roof air intake grille.
• Install the bedroom sensor in the most condensation-prone occupied bedroom.
• Install the lounge sensor in the lounge or room with the home's primary heat source.
• Cluster sensors as much as possible for good signal strength.
• Maintain a 1cm clearance around sensors for battery changes.
• Consider how homeowners can safely access the outside sensor for battery replacement.

Sensors - Mounting:

• When mounting to a wall, ensure the sensor button faces downwards. When mounting on a soffit, ensure the sensor button faces the wall.
• Sensors come with adhesive backs on the battery cover, suitable for most clean, smooth surfaces.
• Clean surfaces with a clean cloth and alcohol, let dry. Remove the adhesive ring cover, press and hold the sensor to the surface for 5 seconds to bond.
• Ensure nothing is within 1cm of the sensor to allow for easy removal for battery changes. A diagram shows a 1cm x 1cm square indicating clearance.
• In the roof space, mount the sensor in an easily spotted location near the roof air intake vent. Do not stick directly to rough sawn timber; screw in a piece of smooth material to attach the sensor.
• Install bedroom and lounge sensors on walls to reduce the influence of roof temperatures.

Sensor - Pairing

Sensors must be paired in the order: Roof, Bedroom, Lounge, then Outside.

• Before pairing, ensure the touchscreen is connected to the Ceiling Controller Box.
• Power on the Ceiling Controller Box and press and hold the button within 10 seconds. The controller will give a long beep, indicating sensors are ready to pair.
• Pair the roof sensor by removing and reinserting its battery (after removing the plastic insulator). After 3 seconds, the sensor's LED will flash 3 times, and the controller will beep.
• Replace the battery cover and mount the roof sensor using its adhesive back.
• Turn on the touchscreen to verify the roof sensor pairing. The bedroom sensor reading will show 99°C, indicating it's the next sensor to be paired.
• Go to the bedroom, insert the battery into the sensor, and hold it up to the desired location. Look for 3 flashes. If fewer than 3 flashes occur, consult the troubleshooting guide.
• Check the touchscreen to confirm successful pairing and identify the next sensor to pair.
• Remember the pairing order: Roof, Bedroom, Lounge, Outside.

Ceiling Controller

Locations:

• Mount the ceiling controller in the lower half of the roof cavity.
• Ensure the mains supply is isolated before making any electrical connections.
• Locate the controller centrally to planned sensor locations, favouring areas where concrete or brick walls are not obstructing signals.
• Ensure the controller is in a location with good Wi-Fi signal strength.
• Avoid mounting near large metal bodies such as hot water cylinders, antennas, heat pump AHUs, or switch panels.

CAUTION: Avoid running TSC data cables parallel to mains cables. If unavoidable, maintain at least a 0.2m distance.

Connection:

1. Mount the ceiling controller using the mounting holes on the side with the damper connection and transformer. Ensure the white sensor receiver module faces upwards.
2. Thread the TSC cable through the cable gland, wire it to the connector, and plug it into the ceiling controller (refer to wiring diagram, page 6).
3. Connect all peripherals: fans and dampers.
4. Ensure the earth spade on the fan is connected to the earth block in the ceiling controller.
5. Ensure all cable glands are tightly fastened and secured to the ceiling controller.
6. DO NOT cross cables over the PCB to reach apertures on the far side. Use an AC fan junction box or AC damper junction box if there are insufficient apertures on the controller box.

A diagram shows correct (✓) and incorrect (❌) cable routing for the ceiling controller connections. It also indicates mounting screw points and the direction of airflow (Up).

Touch Screen Controller

Locations:

• Install indoors only.
• Mount on an inner wall at eye level.
• DO NOT install in wet/damp areas (e.g., laundry or bathrooms), on hot surfaces, in convection currents, or exposed to direct sunlight.
• Ensure at least 0.2m separation between the TSC cable and mains wires to avoid signal interference.
• DO NOT install near any localized heat source.

Mounting:

1. Remove the magnetically attached mounting plate from the TSC using a flat-head screwdriver.
2. Cut an opening in the wall for the flush box and mount it.
3. Screw the mounting plate onto the flush box, ensuring the arrow indicator points upwards.
4. Run the TSC Cable from the roof cavity down to the flush box.
5. Wire the 6-way connector to the cable and plug it into the TSC (refer to wiring diagrams, page 6).
6. Align the arrow and magnets on the back of the TSC with the mounting plate and gently push the controller into the plate until it snaps into place.

❗ Strong magnetic force between the mounting plate and controller could cause jamming of fingers or skin.
