When the heating circuit requires more heating, the level of the valve control signal
is increased.
● 0 V: valve fully closed, 10 V: valve fully open.
3–point
The outputs for opening and closing the valve correspond to the default connection
indicated in the electric diagram.
● Heating circuit 1: Q8 closed, Q9 open.
In use
0–10 V
When the heating circuit requires more heating, the level of the valve control signal
is reduced.
● 0 V: valve fully open, 10 V: valve fully closed
3-point
The outputs for opening and closing the valve are reversed.
● Heating circuit 1: Q8 open, Q9: closed.
The system will keep the flow temperature determined by the heating curve above
this temperature value.
● Typical setting: +20...+25 °C
● Set the the minimum flow temperature slightly above the required room
temperature.
The maximum flow temperature when the outdoor temperature matches the
Design outdoor temperature setting. The system will keep the flow temperature
determined by the heating curve below this temperature value.
● Typical setting, floor heating: concrete floors +35 °C, wooden floors +45 °C
● Check the temperature value from the floor or floor heating supplier (or from the
applicable plans and specifications).
Start by setting the minimum and maximum temperature. The flow temperature can
be adjusted using a six-point heating curve. This menu allows you to adjust each
point separately.
Curve values should be tuned in during the first few heating seasons. See section
Heating.

Target value (setpoint) for domestic hot water tank temperature.
This value determines by how much the domestic hot water temperature needs to
fall below its setpoint before domestic hot water heating will start.
● Typical setting: 4–6 °C
Domestic hot water tank temperature at which DHW heating is started
(target value – start difference).
The heating water used for heating the DHW tank needs to be warmer than the
DHW setpoint temperature (the tank's target temperature). This setting determines
the offset added to the DHW setpoint when charging the tank.
The setpoint for the heating water used for heating the DHW tank (target value +
start difference).
