Explanations:
- NC: Normally Closed, output works as normally closed contact
- NO: Normally Opened, output works as normally open contact
- COM: Common, shared connection
- From wire connector box N, L , PE: There are three 5-pole wire connector
boxes connected in the unit for power distribution
(see diagram, chapter 19)
Note: The plugs can be removed for an easier installation of the connection
cables outside the terminal box.
Note: A resistor is installed at the works for terminal 23-24 (water temperature
sensor). When connecting the Pt1000, this resistor mus
t be removed.
