A higher value will result in a stable butslow control of the flow / duct temperature.Tn (integration time constant) 11185Circuit Setting range Factory setting1 1 ... 999 s 30 sSet a high integration time constant (in seconds) to obtain a slowbut stable reaction to deviations.A low integration time constant will make the controller react fastbut with less stability.M run (running time of the motorized control valve) 11186Circuit Setting range Factory setting1 5 ... 250 s 30 s‘M run’ is the time in seconds it takes the controlled componentto move from fully closed to fully open position. Set the ‘M run’according to the examples or measure the running time by meansof a stop watch.How to calculate the running time of a motorized control valveThe running time of the motorized control valve is calculated usingthe following methods:Seated valvesRunning time =Valve stroke (mm) x actuator speed (sec. / mm)Example: 5.0mmx15sec. /mm=75sec.Rotating valvesRunning time =Turning degrees x actuator speed (sec. / degr.)Example: 90degr. x2sec. /degr. =180sec.Danfoss District Energy VI.GU.A1.02 DEN-SMT/DK 97
