• Boiler sensor
• Tank sensor
• Tank loading pump
• Mixed heating circuit pump, mixed heating circuit open/closed
and flow sensor of heating circuit 1
• Mixed heating circuit pump, mixed heating circuit open/closed
and flow sensor of heating circuit 2
The following components are connected to the second control
device with bus address 20:
• Mixed heating circuit pump, mixed heating circuit open/closed
and flow sensor of heating circuit 3
