Select this option if shunt controlled additional heat is
connected.
Set when the addition is to start, the minimum run time
and the minimum temperature for external addition with
shunt here. External addition with shunt is for example
a wood/oil/gas/pellet boiler.
You can set shunt valve amplification and shunt valve
waiting time.
Selecting "prioritised additional heat" uses the heat from
the external additional heat instead of the heat pump.
The shunt valve is regulated as long as heat is available,
otherwise the shunt valve is closed.

The type of heating distribution system the heating
medium pump works towards is set here.

perature.
MENU 5.1.22 - HEAT PUMP TESTING
NOTE
This menu is intended for testing SMO 40 ac-
cording to different standards.
Use of this menu for other reasons may result
in your installation not functioning as intended.
This menu contains several sub-menus, one for each
standard.
MENU 5.1.23 - COMPRESSOR CURVE
Caution
This menu is only displayed if SMO 40 is con-
nected to a heat pump with inverter controlled
compressor.
Set whether the compressor in the heat pump should
work to a particular curve under specific requirements
or if it should work to predefined curves.
You set a curve for a demand (heat, hot water etc.) by
unticking "auto", turning the control knob until a temper-
ature is marked and pressing OK. You can now set at
what temperatures the max. and min. frequencies, re-
spectively will occur.
This menu can consist of several windows (one for each
available demand), use the navigation arrows in the top
left corner to change between the windows.
