  • Page 32 1.8 Optimization of temperature control P-share • Change repeatedly between set temperatures of 18 °C and 22 °C while observing the settling behavior of the actual temperature. Increase the P-share gradually. Higher values will increase the settling speed, to high values make the system oscillate. The P-share has been set correctly when the actual temperature remains stable near the set temperature after only 2-3 overshoots.
