Connecting status notifications

The two potential-free contacts, Status, can be configured as required. De­
pending on the setting, a particular status can be transmitted by the boiler.
Connect a relay contact to the C and No terminals when the status speci­
fied occurs (a relay contact will open in the C and Nc terminals in these
cases). Select the desired status notification (setting) using parameter
and .

6.1.2 Connecting 0–10 V output
The 0-10 contact can be used to connect a PWM system pump. Depend­
ing on the make and type of pump, the pump can be controlled by a 0–10
V or a signal. The speed of the pump is modulated based on the signal re­
ceived from the boiler.
Connect the system pump controller to connector 0-10.
Select the type of signal (setting) that will be received from the boiler us­
ing the parameter
Select the type of signal that controls the pump using the parameter
.
Caution
If possible, use the pump modulation signal. This provides the
most accurate pump control.
If the automatic burner unit does not support pump modulation,
the pump will behave as an on/off pump.
