Start guide
NOTE
There must be water in the climate system
before SMO S40 is started.
1.
Start SMO S40 by pressing the on/off button once
(SF1).
2.
Follow the instructions in the display’s start guide.
If the start guide does not start when you start the
SMO S40, start it manually in menu 7.7.
TIP
See the section "Control – Introduction" for a
more detailed introduction to the installation's
control system (operation, menus, etc.).
COMMISSIONING
The first time the installation is started a start guide is
started. The start guide instructions state what needs
to carried out at the first start together with a run
through of the installation’s basic settings.
The start guide ensures that the start-up is carried out
correctly and, for this reason, cannot be skipped.
During the start-up guide, the reversing valves and the
shunt are run back and forth to help vent the heat pump.
Caution
As long as the start guide is active, no function
in SMO S40 will start automatically.
The start guide will appear at each restart of
SMO S40, until it is deselected on the last
page.

Setting the
cooling/heating curve
In menu Curve, heating you can view the heating curve
for your house. The task of the curve is to give an even
indoor temperature, regardless of the outdoor temper-
ature, and thereby energy-efficient operation. Based on
this curve, the SMO S40 determines the temperature
of the water to the climate system (the supply temper-
ature) and thus the indoor temperature.
CURVE COEFFICIENT
The slope of the heating curve indicates how many de-
grees the supply temperature is to be increased/reduced
when the outdoor temperature drops/increases. A
steeper slope means a higher supply temperature at a
certain outdoor temperature.

The optimum curve slope depends on the climate con-
ditions in your location, whether the house has radiators,
fan coils or underfloor heating and how well insulated
the house is.
The heating curve is set when the heating installation
is installed, but may need adjusting later. Normally, the
curve will not need further adjustment.
