Heating controller Lago 0321

• For the control of:
- 1 x Heat generator, single-stage
- 1 x direct heating circuit
- 1 x mixer heating circuit (3-point PI controller)
- 1 x hot water

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

If no Heat generator sensor is connected, the device can be used for a mixer extension. If a heat generator sensor is connected and an address (BUS ID) is set, the Heat generator can be used in a cascade. It is then controlled by a system manager.
