8.2 Filling and bleeding
DANGER
Imminent danger to life and limb
The fluid escaping during bleeding can be very
hot. Wear protective clothing and cover vent hole
with a cloth if required
Illustr. 8.2 Bleeding
Flush heating system thoroughly before initial
operation
– Fill system completely and bleed heating circuit
with the help of the venting valve (6).
– Bleed capillary (4a) of the differential pressure
regulator (4):
– To do so, loosen screw (4b) slightly, spanner size
8, so that the air can escape.
– Bleed until only heating fluid is escaping.
– Tighten screw and check connection for leaks.
– Bleed potable water circuit with the venting valve
(12) or by drawing off water at maximum capacity
(air is flushed out).

8.3 Functional control
The following points must be observed for a functional
control of the dwelling station "Regudis W":
When using a heat meter, no volume flow must be
shown if the heating circuit of the dwelling is closed
and the draw off is not in operation
Heating circuit to the dwelling:
– Open heating circuit / radiator valves of the
dwelling.
– Check whether the required flow temperature
(e.g. 65 °C) is reached at the connections D and F
(illustr. 4.3).
– Check whether the required return temperature
(e.g. 50 °C) is reached at the connections E and G
(illustr. 4.3). Adjust setting of the radiator lockshield
4a
valves in the heating circuit if required.
4b
– The heat exchanger must not heat up during
heating operation
4
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/ 5.2 – 2): The heat exchanger must cool down
after drawing off has been completed.
8.4 Setting zone valve
The zone valve (illustr. 5.1/5.2 – 5) can be equipped
with an actuator for heating circuit control (connection
thread M 30 x 1.5).
8.5 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
