Start-Up And Inspection; Setting The Cooling/Heating Curve - Nibe SMO 20 Installer Manual

Start-up and inspection

START GUIDE
NOTE
There must be water in the climate system before
the switch is set to " ".
1. Set switch (SF1) on SMO 20 to position " ".
2. Follow the instructions in the display's start guide. If the
start guide does not start when you start the SMO 20,
you can start it manually in menu 5.7.
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 star-
ted. The start guide instructions state what needs to carried
out at the first start together with a run through of the in-
stallation's basic settings.
The start guide ensures that the start-up is carried out cor-
rectly 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 20 will start automatically.
The start guide will appear at each restart of
SMO 20, until it is deselected on the last page.

Setting the cooling/heating
curve
In the menus "heating curve" and "curve", you can see the
heating and cooling curves for your house. The purpose of
the curves is to provide an even indoor temperature, regard-
less of the outdoor temperature, and thereby energy-effi-
cient operation. Based on these curves, SMO 20 determines
the temperature of the water to the climate system (the
supply temperature) and thus the indoor temperature.
CURVE COEFFICIENT
The slopes of the heating /cooling curves indicate how many
degrees the supply temperature is to be increased/reduced
when the outdoor temperature drops/increases. A steeper
slope means a higher supply temperature for heating or a
lower supply temperature for cooling at a certain outdoor
temperature.
