Installation of RLS 45 K control (230 V)

Read the separately enclosed safety instructions for PushPull ventilation units before making the electrical connection. Follow the instructions. Commissioning only permitted by a qualified electrician with fully assembled system components.

Danger of short circuit/fire if moisture penetrates the control. Short circuits and fire can lead to serious injuries with fatal consequences.

Ensure a correct, tight cable feed.

DANGER Danger of short circuit/fire in the event of overload due to incorrect connection or connection of too many units to an RLS 45 K (serious injury, death).

Connect units in accordance with connection diagram. Observe permissible number of ventilation units per room air control/power unit.

DANGER Risk of electric shock if the 12 V extra-low voltage and 230 V are not or insufficiently isolated (serious injury, death).

Ensure a safety distance between 230 V and 12 V (SELV). Ensure minimum distance of 8 mm. Ensure a phase balance between all components connected to the ventilation system.

Risk of electric shock if an RLS 45 K control is installed within protection zone 0, 1 or 2 and penetrating moisture (serious injury, death).

No IP protection present (IP 00). The room air control may only be installed outside protective zones 0, 1 or 2.

Install the RLS 45 K in a deep flush-mounted box. When wiring several unit pairs/ventilation units, always use a deep/double flush-mounted box. Strip the connection cables sufficiently.

  1. Switch off the mains fuse and secure it against being switched on again.
  2. Remove the frame of the RLS 45 K.
  3. Cut the power cable and connection cable to length.
  4. Wire the RV 2 ventilation units to the connector plug of the RS 485 bus (bus terminals) → Plug sticker and Connection and wiring diagrams.
  5. Insert the connector plug into the socket.
  6. Insert the RLS 45 K into the flush-mounted box and screw it in place.
  7. Fit the frame. When using a PP 45 HYI sensor, ensure that the sensor opening is correctly positioned over the HYI and that the frame snaps into place.
  8. Commissioning the ventilation system→ chapter Commissioning, setting parameters.
  9. Call up service mode and configure the system components.

Use the automatic search function (Plug & Play) for an even number of RV 2 units. The ventilation units are automatically configured as supply air or exhaust air units → following chapter.
