05. The temperature need for the house

General information
The setting of the curve inclination and
the curve adjustment
The setting of the temperature need for the house is a central part of the
boilers control system, be
system how much temperature your specific house need at different out door
temperatures. The setting for the house is called curve inclination and curve
adjustment. It is very important that the curve inclination and curve
adjustment will be correctly done to get as good function and as good
economy as possible.
One building may need e.g. 30 ° water temperature to the radiators when it is
0°C outdoor temperature, while another building maybe need 40°C. The
difference between the buildings depends on e.g. the sizes of the radiators,
numbers of radiators and how well insulated the building is.
You decide the temperature need for your house yourself by setting two values in the
control system of the boiler. You find the values in M
exactly know the temperature need for your house, it may take
some time reach a correct value. The best way to achieve the correct setting
is to choose operation without room sensor (see me
The outdoor temperature only decides the temperature to the radiators.
It is important during the adjustment period that:
- the night temperature function is not chosen.
- all thermostatic valves on the radiators are maximum opened.
- the out door temperature is lower than +5°C (use the factory settings if the
temperature outside is higher than +5°C until the temperature decrease to a low level).
- the radiator system is correctly functioning and adjusted.

Basic adjustment

1) The first setting tells how much temperature the radiator system need at
- 15°C out door temperature to achieve a correct indoor temperature inside the
house. The setting is called CURVE INCL and found in the menu
S . If you don t know the value, use the crib next page.
2) Next value to set is the CURVE ADJUST in menu
buildings need a parallel push up or pull down of the curve inclination.
0 means that the curve is not pushed or pulled at all. +5°
means that the temperature out to the radiators is always +5°C higher at
all outdoor temperatures, and -5°C lower if -5° is chosen.
3) Let the settings be valid for one or some days, check the room
temperature. Follow the instructions below If it s too warm or cold.
Adjustment (if the out door temperature is lover than 0°C)
- if the room temperature is too low: Increase the value CURVE INCL a
couple of degrees. Wait another day to feel the improvement before next
adjustment.
If the room temperature is to high: Decrease the value CURVE INCL a
couple of degrees. Wait another day to feel the improvement before next
adjustment.
Adjustment (if the out door temperature is higher than 0°C)
- if the room temperature is too low: Increase the value CURVE ADJUST a
couple of degrees. Wait another day to feel the improvement before next
adjustment.
- If the room temperature is too high: Decrease the value CURVE ADJUST
a couple of degrees. Wait another day to feel the improvement before next
adjustment
