> Shut down protection during change over from hot
water to heating
B Set how long it should take before a heating demand
may be deactivated after hot water production. This
ensures that the hot water amount that goes out into
the heating circuit after production of hot water does
not become a reason for incorrect deactivation of a
heating demand.
> Minimum outdoor temperature
B Set the minimum outdoor temperature for the heat
curve.
16.1.2 Circuit 1 Heating
Here are:
• External set point value
• Use temperature from circuit with highest
temperature
• Type of heating system
• Highest permitted flow temperature T1
• Lowest permitted flow temperature T1
• Heat curve
• Heat curve hysteresis heat pump x
• Room sensor
• Room temperature program
> External set point value
B Change to Yes if an external signal 0-10V should
control the flow temperature (fixed set point value).
1V= 10 °C, 10V = 80 °C (linear function).
> Use temperature from circuit with highest
temperature
B Change to Yes if the set point value for Circuit 1
should be the highest of Circuit x's set point values.
Only circuits in Winter operation are included.
This function means that the set point value for
Circuit 1 is always adapted to current need.
In the event of Yes, Summer/winter operation can be
set also for the mixed circuits.
The function is used when Circuit 1 only consists of a
buffer tank.
> Type of heating system
B Select type of heating system, Radiator or
Underfloor.
B Change to Radiator at Yes in Use temperature from
circuit with highest temperature.
B Change to Radiator at External heat source (solar,
firewood).
The factory settings for the Radiator have a curve value
(flow temperature) of 22 °C at 20 °C an outdoor
temperature, 37.4 °C at –2.5 °C and 60 °C at -35 °C at
an outdoor temperature (the high point of the curve).
The factory settings for the Underfloor have a curve
value (flow temperature) of 22 °C at 20 °C outdoor
temperature, 27.2 °C at -2.5°C and 35 °C at -35 °C
outdoor temperature.
At a temperature higher than 20 °C, the same curve
value applies as for 20 °C.
Factory setting 180s
Lowest value 0s
Highest value 600s

Lowest value -35,0 °C
Highest value -10,0 °C

Factory setting No
Alternative Yes/No
Tab. 48 External set point value
Ensure that the incoming signal does not
generate higher flow temperature than what
Circuit 1 withstands.
All safety functions for the heating system
must be handled by the external equipment.
