... could be ordered with a wireless remote control. 

The description on Ali Express indicated that it had a number of programmable options that might be fun to explore.

1.  Start with the power removed from the control unit
2.  Hold the MENU button and, while still holding MENU, turn the power on
3.  Continue holding MENU for a few seconds
4.  The backlight should flash twice
5.  The remote is now linked

This photo shows a time setting of 1 minute.  To change a setting note that the Hour, Minute or Second indicator is flashing. 
To set hours make sure the H is flashing. To change to setting minutes hold the MENU button for several seconds and the next letter will flash
Once the chosen letter is flashing use the UP/Down arrows or knob to set the value.
When done short press the MENU button to get to the next function.

9 Functions are described as follows



Function 1- Slow start time setting: 000-100 (0-10 seconds) slow start time adjustable, default 1 second;

Function 2- Slow down time setting: 000-100 (0-10 seconds) slow down time adjustable, default 1 second;

Function 3- speed limit setting: 000-080 (0-80%) adjustable, default 0;

Function 4- speed limit setting: 000-100 (0-100%) adjustable, default 100%;

Function 5- Add or subtract speed value setting: 1, 2, 5, 10, 15, 20, 25 The percentage of the corresponding change of the speed when the add or subtract key is pressed once,

1%, 2%, 5%, 10%, 15%, 20%, 25%, default 1 (1%);

Function 6- Setting of under voltage protection value: 0-55V adjustable, setting 0V means no under voltage protection function, continuous 200ms over limit is regarded as effective;

Function 7- Setting of over current protection value: 0-20A adjustable (starting at 0.5A, increasing at 0.5A), setting of 0A indicates no over current protection function;

Function 8- Over current protection mode setting: Mode 1 directly shut down the output when the current reaches the protection value of 200ms, mode 2 current reaches the protection

Value 200ms maintain the current limit set protection current value, default mode 1;

Function 9- Power-on startup mode: Mode 1 motor does not start after power-on, mode 2 motor starts after power-on, default mode 1;
