a boiler group (zone).
Connect the three-way valve as follows:
Earth
N Neutral
Open
Closed
5.3.18 Connecting a system pump for mix group

5.3.19 Connecting status notifications
The two potential-free contacts, Status, can be configured as required.
Depending on the setting, a particular status can be transmitted by the
boiler.
Connect a relais as follows:
Nc Normally closed contact. Contact will open when status occurs.
C Main contact.
No Normally opened contact. Contact will close when status occurs.
Select the desired status notification (setting) using parameter EP018 and
EP019.
5.3.20 Connecting 0–10 V output
The 0-10 contact can be used to connect a PWM system pump. The
speed of the pump is modulated based on the signal received from the
boiler. Depending on the make and type of pump, the pump can be
controlled by a 0–10 V or a PWM signal.
Connect the system pump controller to connector 0-10.
Select the type of signal that will be sent from the boiler using the
parameter EP029.
Select the type of signal that controls the pump using the parameter
EP028.
