TECHNICAL MANUAL GS 4x.00 KNX – ENGLISH 8. Temperature control 8.1 Temperature control – heating and cooling PI control: A PI control is a constant control that comprises a proportional part (P-part) and an integral share (I-share). The size of the P-part is indicated in Kelvin, the I-share in minutes. At a constant PI control, the manipulated variables are operated in proportional steps up to a maximum value.
