Automation, sensing and robotics • Digital potentiometer

I need to control the resistance between 1.7K Ohms and 2.2K Ohms with a Raspberry Pi 3 (possibly might be using a Zero W instead).

I assume I need a digital potentiometer, but how do I control it with the Pi?

This is to control the temperature of a vehicle diesel heater, so 12v and low current.

Any suggestions for a digital pot to use? Any pointers to tutorials (videos?) that explain how to do it?
