Our engineer checked the schematic, and has the following guess.
The motor itself should be a DC 110V motor, and the wired remote changes the motor direction by change the power polarity supplied to DC motor.
See the schematic here and following explanation

The wired remote is just a 3-state switch, first state is contact 1 closed, motor forward (or reverse), second state is contact 2 closed, motor reverse (or forward), third state is both contact released, motor stop.
To use our relay to control, it is a typical motor forward and reverse application, you can refer to upper right relay connection diagram to connect the wires.
Set our receiver to latch mode, program remote button A to channel 1, B to channel 2, and C to release (by press both learn buttons, and learn button C).
In theory, when you press A-> motor forwards, B-> motor backwards, C-> motor releases.
** Your motor claims to be max 10.6A current, it is exceeding our receiver’s max current capability, I’m a bit worried, so if connect directly, receiver back track may generate more heat, so please remove all load to motor first, so it won’t exceed current during testing.
** The wires are carrying high voltage, please take care and proceed with caution when connect the wires.
** Please check the connection first, before applying power.
