Wireless Signal Receiver for HVAC Cassettes

The Mitsubishi PAR-WSC009FA-E is a wireless signal receiver designed for Nv-Series NTXCKS and CITY MULTI TPLFY ceiling cassette units. It enables the PAR-SL100A-E remote controller to manage individual vane settings and dual set points on PLFY models. The unit supports direct and indirect airflow control alongside 3D i-see sensor compatibility. One receiver is required per indoor cassette unit for operation.

Verify CN90 Connection and Controller Pairing

Before ordering, confirm that your ceiling cassette unit provides a CN90 connection point for the receiver. You must also have a PAR-SL100A-E remote controller available, as the receiver cannot function without it. Ensure the installation plan accounts for one receiver paired to each cassette unit in the system. Compatibility is limited to the specific Nv-Series and TPLFY models listed in the specifications.

Stable Signal Relay Under Continuous Operation

The receiver maintains a consistent communication link with the remote controller during extended heating or cooling cycles. It relays vane position and sensor data without interruption, supporting the 3D i-see sensor's ongoing occupancy and temperature scanning. The CN90 interface provides a fixed wired pathway that avoids the dropouts sometimes seen with battery-powered wireless bridges. Performance remains steady across the full operating envelope of the connected cassette unit.
