Controller for Carrier 4 pipe fan coil 42EM

[edit: I'm a dummy, can't even get the model right, it's a 42EM]

Does anyone know which model remote controller goes with this 42EM carrier fan coil unit.

The unit has an NTC communicating controller attached but I can't identify the remote controller required to match it.

I have found details on the CRC2 and Aquasmart controls but they don't mention this fan coil model.

Any help welcomed.
