10.2 Clip-in
10.2.1 AGU2.500...
Mixing circuit pump and mixing valve
- Voltage AC 230 V +10 % -15 %
- Current 5 mA ... 1 A, cos ϕ > 0.8
When assigning loads to the outputs, the total current draw of the LMU… system must
be taken into consideration!
Flow sensor NTC 10 kΩ like boiler sensor
10.2.2 AGU2.51x
Up to 3 outputs (K1...K3)
When using 2 clip-in modules with the LMU…, only 2 outputs possible
- Voltage AC 230 V +10 % -15 %
- Current 5 mA ... 1 A, cos ϕ > 0.8
When assigning loads to outputs K1...K3, the total current draw of the LMU… system
must be taken into consideration!
