The set heating curve always takes priority. The room sensor can only increase
or decrease the heat beyond the set heating curve to a certain extent. Where
operating without a room sensor, the selected heating curve determines the
flow temperature supplied to the radiators.
The house heating curve
The heating curve is the central part of the product’s control system. It
is the heating curve that determines the compensated flow temperature
requirements for your property depending on the outdoor temperatures. It is
important that the heating curve is correctly adjusted so that you can achieve
the best operation and economy possible.
One property requires a radiator temperature of 30°C when the outdoor
temperature is 0°C, whilst a different property requires 40°C. The difference
between different properties is determined by the radiator surface area, the
number of radiators and how well insulated the house is.
Adjustment of default values for the heating curve
You define the heating curve for your property yourself by setting two values
in the product control system. You can do this in the menu Installer/Settings/
Heating circuit/Inclination or Adjustment. Ask your installation engineer to
help you to enter these values.
It is extremely important to set the heating curve, and in some cases this
process may take several weeks. The best way of doing this, upon initial
start-up, is to select operation without any room sensor. The system then
operates using the outdoor temperature reading and the property’s heating
curve only. Once the correct heating curve has been set, the room sensor
can be activated for even more adapted operation.
During the adjustment period it is important that:
• The night reduction function is not selected.
• All thermostat valves on the radiators are fully opened.
(This is to find the lowest curve for the most economical use of the heat
pump.)
• The outside temperature is no higher than +5°C.
• The heating circuit is operational and correctly adjusted between
different loops.
