11.4 User levels
The controller features specified user levels, which enables that
only corresponding user groups can change settings. The device
is mainly used on
End user –level. The mechanic installing the
heat pump uses device on Expert – level. Different user levels
can be accessed from Service/settings –menu.
11.5 Heating settings
The room temperature is dependent of several factors. During
warn seasons, the heat reflected from the sun, and heat given off
by people and various devices, often is enough to keep the room
temperature at a sufficient level. When the air cools down, a
heating system is needed. The colder it is outside, the warmer
the water is that circulates in the heating system. For the room
temperature to be at the right level, the basic settings must be
correct.
ADJUSTING WITH A HEATING CURVE
The starting point of the heating curve is the heat pump’s
damped outdoor temperature (average temperature of 15h) and
the heating system’s measured output water temperature. The
slope of the automation’s curve can be seen at the intersection
point of the two values. This is separately set for each heating
area.
The settings are made in the Maintenance/settings menu
NOTE! The heating curve setting is based on a room tempera-
ture of 20°C. If the room temperature set point is changed, the
heating curve is changed automatically according to the new
value.
Example values for adjusting the slope of the heating curve:
Factory setting: 0,5
Floor heating: 0,3 – 0,5
Radiator heating: 0,5 – 1,0
Air heating: 0,5 – 1,0
Room temperature change
If you would like to decrease or increase the room temperature
either temporarily or permanently, do this by changing the
Com-
fort set point.
NOTE!
Floor heating or radiator heating thermostats may limit
the room temperature rise, so that they must also be adjusted
higher.
Readjusting the default settings
If the desired room temperature is not obtained, it is necessary to
re-adjust.
Cold weather:
- If the room temperature is too low, increase the heating
curve slope value.
