You can select the type of action: 1- direct action (SP>PV), so initialy, increasing PV decrease the error and also decrease the LMN (value on actuator) 2- reverse action (PV>SP),so initialy, decreasing PV decrease the error and also decrease the LMN (value on actuator)-->(negative P) Also check this topic: Determine reverse or direct action of PIDregards |
