CHARGE PUMP FOR HEAT PUMP 1 AND 2
Connect circulation pump (AA35-GP12.1-EB101) to the
terminal block AA100-X2 (PE), AA100-X3 (N) and AA100-
X5:3 (230 V).
Control signal for AA35-GP12.1-EB101 is connected to
terminal block AA100-X12:1 (Pulse/0–10V) (PWM1) and
GND on any block X13.
If two heat pumps are connected to SMO S40 the circu-
lation pump (AA35-GP12.2-EB102) must be connected
to the terminal block AA100-X2 (PE), AA100-X3 (N) and
AA100-X5:4 (230 V). Control signal for (AA35-GP12.2-
EB102) is connected to terminal block AA100-X12:3
(Pulse/0–10V) (PWM0) and GND on any block X13.
TIP
Two charge pumps can be connected to and
controlled by SMO S40. Several charge pumps
can be connected, if accessory boards (AXC)
are used, two pumps per board.

Outside sensor
The outdoor sensor (BT1) is placed in the shade on a
wall facing north or north-west, so it is unaffected e.g.
by the morning sun.
The outdoor sensor is connected to terminal block
AA100-X10:1 and to any input on terminal block AA100-
X11.
If a conduit is used it must be sealed to prevent condens-
ation in the sensor capsule.

Temperature sensor, hot water charging
The temperature sensor, hot water charging (BT6) is
placed in the submerged tube on the water heater.
Connect the sensor to terminal block AA100-X10:3 and
to any input on terminal block AA100-X11.
Settings for hot water are made in menu 2 "Hot water".
