Drawing off hot water:
– Start drawing off hot water at a constant volume
flow.
– The draw off temperature must reach the required
setting. Check setting of the thermostatic
temperature controller if necessary (illustr. 8.3).
– Closing test of proportional flow controller (illustr.
5.1): The heat exchanger must cool down after
drawing off has been completed.
8.3 Setting zone valve
The zone valve (illustr. 5.1 – 5) can be equipped with
an actuator for heating circuit control (connection
thread M 30 x 1.5).
8.4 Setting potable water temperature
When leaving the factory, the temperature controller
is set to position 3. This corresponds to a potable
water temperature of 50 °C. The setting can be
adjusted to the required potable water
Control range: 40 – 70 °C
1 = approx. 40 °C
2 = approx. 45 °C
3 = approx. 50 °C
4 = approx. 55 °C
5 = approx. 60 °C
6 = approx. 65 °C
7 = approx. 70 °C

7.5 Setting flow temperature heating circuit
When leaving the factory, the temperature controller
is set to position 3. This corresponds to a heating
water temperature of 35 °C. The setting can be
adjusted to the required heating water temperature.
Control range: 25 – 50 °C
1 = approx. 25 °C
2 = approx. 30 °C
3 = approx. 35 °C
4 = approx. 40 °C
5 = approx. 45 °C
6 = approx. 50 °C

8.6 Settings differential pressure regulator
The factory setting of the differential pressure regulator
is 150 mbar.
Higher settings increase the draw off capacity, but
can generate noise in the heating circuit (observe de-
livery capacity of the supply pump!).
