The fl ow-through step-controlled heating module has
been described in the SMO manual in auxiliary sec-
tion fl ow-through step-controlled heating module. It
is controlled by three potential-free relays in the con-
trol module (3 linear steps). For step-control of the
heating module, you can also use two relays (2 linear
steps), therefore, the third relay can serve for control
of the submersible heater in the hot water heater/buf-
fer tank.
The steps occur in at least 1 minute intervals and are
switched off in at least 3 second intervals.
Step 1 is connected to clamp X2:2 at the auxiliary
relay card (AA7).
Step 2 is connected to clamp X2:4 at the auxiliary
relay card (AA7).
Step 3 or submersible heater in the hot water heater/
buffer tank are connected to clamp X2:6 at the auxil-
iary relay card (AA7).
Settings of the fl ow-through step-controlled heating
module are entered in menu 4.9.3 and menu 5.1.12.
All auxiliary heaters can be blocked by connecting
the potential-free relay function to clamp X2 of the
program-controlled input (see SMO manual, Chap-
ter Electrical connections, section Optional Connec-
tions).

The emergency mode relay can serve to start the
heating module – for the purpose of temperature reg-
ulation, connect the thermostat to the control circuit.
Make sure that the heating medium fl ows through the
fl ow-through heating element.
If the relay is to be used for control voltage, connect
the power supply clamps X1:1 and X1:2, as well as
neutral conductor and control voltage of the auxiliary
preheater to clamps X1:0 (N) and X1:4 (L).
