Sounds like you are going for 'digital control'. 
The max speed must be more than enough to satisfy the process. Easiest way is to have one thermostat controlling the low speed function and a second TS bringing on the high speed winding if the motor low speed is insufficient (after a short time delay) to satisfy temperature.
Two stage control is a more common term, if the above describes your intent.
