The buffer cylinder is fed with heating water from the
heat source and is used as intermediate storage for hot
water being transported onwards to the heating circuit.
The buffer cylinder is made of steel and is provided with
a red outer protective coating. It has nine connections
for the heating pipes, five of which must be blanked off
with plugs fitted on site. In addition, there are four
openings with immersion sensor pockets for themal sen-
sors, two of which must likewise be blanked off with
plugs fitted on site. Two immersion sensor pockets are
included with the cylinder.

Fig. 2.2 Connections (rear)
Key:
1 Water connection, flow R 1 1/2“
2 Sleeve, R 3/4", for upper temperature sensor
3 Connection, to be blanked off with R 1 1/2" plug
4 Sleeve, to be blanked off with R 3/4" plug
5 Connection, to be blanked off with R 1 1/2" plug
6 Sleeve, R 3/4", for lower temperature sensor
7 Water connection, return R 1 1/2“
8 Sleeve, to be blanked off with R 1/2" plug
9 Water connection, return R 1 1/2“
10 Connection, to be blanked off with R 1 1/2" plug
11 Connection, to be blanked off with R 1 1/2" plug
12 Water connection, flow R 1 1/2“
13 Venting sleeve (to be blanked off with R 1 1/2" plug)
Connection to the heating system and the heat
source
The heating circuits must be connected symmetrically.
Either
- Connection 12 (or optionally 13): Heating flow
- Connection 9: Heating return
- Connection 1: Flow from the heat source
- Connection 7: Return to the heat source
or
- Connection 12: Flow from the heat source
- Connection 9: Return to the heat source
- Connection 1 (or optionally 13): Heating flow
- Connection 7: Heating return
Other connection schemes for the heating circuits are
not permissible.
Alternatively, you can connect the venting sleeve 13 as
the flow instead of connection 12 or connection 1. In this
case, blank off the unneeded connection 12 or connec-
tion 1 with a R 1 1/2" plug. Then fit an additional external
ventilation (T-piece, automatic air vent).
