When the return temperature falls below or gets higher than the set value, the controller automatically changes the desired flow temperature to obtain an acceptable return temperature. The influence is set in lines 4035 and 4036. VI.KT.F2.02 VI.KT.F2.02 © Danfoss 06/2008 DH-SMT/DK DH-SMT/DK © Danfoss 06/2008... -

During auto tuning the circulation pump for tap water must be switched off. This is done automatically if the pump is controlled by the ECL controller. Auto tuning is only applicable in connection with valves that are approved for auto tuning, i.e. the Danfoss types VB 2 and VM 2 with split characteristic. VI.KT.F2.02 VI.KT.F2.02 ©... -

A PI control does the same as a P control, but the offset will disappear over time. A long ‘Intgr. time’ will give a slow but stable control, and a short ‘Intgr. time’ will result in a fast control but with a higher risk of oscillations.
