Heating controller Lago 0321

• To control:
1 x heat generator, one-level
- 1 x direct heating circuit
1 x mixing heating circuit (3-point PI controller)
- 1 x hot water

Alternatively the pump relay of the direct heating circuit can also be used for the following functions:
• Circulation pump
• Return flow boost
• Collector pump

If a heat generator sensor cannot be connected, the device can be used for a mixer add-on. If a heat generator sensor is connected and an valid address is configured (BUS-ID), the heat generator can be used in a cascade. This can then be controlled by a system manager.
