Connecting a domestic hot water (DHW) pump
Connecting a domestic hot water (DHW) pump. The maximum power
consumption is 300 VA.
Connect the pump as follows:
Earth
N Neutral
L Phase
Connecting a mixing valve
The mixing valve connector can be used to connect a mixing valve (230
VAC) for use in a boiler group (zone).
Connect the mixing valve as follows:
Earth
N Neutral
Open
Close
Connecting the system pump
1. Connect a system pump to the Pump terminals of the connector.
Important
The maximum power consumption is 300 VA.
The function of the system pump can be changed using parameters
PP015, PP016 and PP018.
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.
Connecting the calorifier sensor/thermostat
A calorifier sensor or thermostat can be connected to the Tdhw terminals
of the connector. Only NTC 10 kΩ/25°C sensors can be used.
Important
For boilers with an SCB-10 PCB, the calorifier sensor/thermostat
must be connected to the SCB-10 PCB.
