Energy mesurement
MULTICAL® 603 functions s follows:
The flow sensor registers the volume of wter tht circultes through the system in cubic
metres (m3).
The temperture sensors plced in inlet nd outlet register the cooling, i.e. the difference
between inlet nd outlet tempertures.
MULTICAL® 603 clcultes the energy consumption on the bsis of the volume of wter
nd the temperture difference.
Redings in the disply
When one of the rrow keys ( or ) is ctivted, new primry reding is displyed.
The primry key is used for retrieving historicl redings nd verge vlues nd for
returning to primry redings.
Four minutes fter the ltest ctivtion of ny front key, the disply utomticlly chnges
to energy consumption.
