Temperature Controller - Staveb AG

Parameter Functions and Definitions 5-25Function: This parameter allows you to configure the output period (controlperiod) which is the minimum amount of time between ON cycles of theoutput. Set the control period taking the control characteristics and theelectrical life expectancy of the output devices into consideration (especially ifa mechanical relay is used).• When the standard control mode is selected, use the Control Period(OUT1) parameter. The Control Period (OUT2) parameter cannot beused (see Table 4.C).• When the heating and cooling control mode is selected, the controlperiod can be set independently for the heating and cooling outputs.Use the Control Period (OUT1) parameter to set the control output 1side control period, and use the Control Period (OUT2) parameter toset the control output 2 side control period (see Table 4.C).Table 5.AAParameter Configurable Range Units Default ValueControl Period (OUT1) 1…99 Second 20Control Period (OUT2) 1…99 Second 20Related ParameterPID/ON/OFF (Initial Setting function group) (p. 5-22)Direct/Reverse OperationFunction: This parameter allows you to configure the controller for the director reverse operation of the manipulated variable (MV). Direct operation refersto control where the manipulated variable is increased according to theincrease in the process value. Alternatively, reverse operation refers to controlwhere the manipulated variable is increased according to the decrease in theprocess value.Table 5.ABSelectionsor-r: Reverse operationor-d: Direct operationDefault Selectionor-rPublication 900-UM003C-EN-E - January 2004
