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.
