Powering 24 VAC motor with relay, potentiometer, and bluetooth

I need to power this through a wall:

I'm still fairly new to Arduinos and have not used them a lot. This is a company (summer intern) project, so I just wanted to confirm my process is correct before buying parts. I need to control the motor (above) from the outside of a closed room. I plan on doing this using Bluetooth, Arduinos and a potentiometer on my side. In the room, another Arduino and bluetooth with a relay connecting the motor and arduino. This should allow me to change the knob of the motor to varying angles, correct?

Parts list:
2: Arduino uno R3
2: HC-05 Bluetooths
1: Relay
1: Potentiometer

Links to exact parts I plan on buying:

Thanks in advance for any and all help.
