Whenthisfunctionisactive,theadditionalpumpservesasthecirculatingpump.Thepumpcontrolsthevale
whichmixesthehotwaterbetweentheCHboilerandtheDHWreceivers.Thefollowingparametersneedto
beconfiguredforthecirculatingpumptoworkcorrectly:
Operationtime
Thisparametersdefinesthetimeofpumpoperationduringitsactivity.
Pausetime
Thisparameterdefinestheperiodoftimebetweencirculatingpumpactivations‐theperiodoftimewhenthe
pumpremainsinactive.
Operationschedule
Theusermayprogramadailyscheduleofpumpoperationandinactivity,withtheaccuracyof30minutes.The
pumpwillbeenabledatthefrequencydefinedinPausetimeparameteranditwillremainactiveforthetime
definedasOperationtime.
