For the property owner
Room temp. reduced °C -2 (0 to -30)
The menu is displayed if room sensors for the respective
heating circuit are installed. You define here by how
many degrees the room temperature is to be reduced
during the various scheduled reduction periods, e.g.
Night reduction, Holiday etc.
Primary flow reduced °C -3 (0 to -30)
The menu is displayed if room sensors for the respective
heating circuit are not installed. This is used to set
the number of degrees by which the primary flow
temperature for the respective heating system will be
reduced during the various scheduled reduction periods.
Drying period Off (Off/Type1/Type2).
Is activated to limit the flow temperature in connection with
construction/installation. The setting automatically passes
to “Off” after completed cycle.
Type 1
Constant primary flow temperature of 25 °C during the
first day and the subsequent three days. During the next
four days the primary flow temperature is set according
to the “Max Primary Flow” menu. However, it cannot be
higher than 55 °C.
Type 2
25 °C primary flow temperature during the first day.
The temperature is raised by 5 degrees per day until
the set temperature in the “Max primary flow” menu is
obtained. During the next 10 days the flow temperature
is constant according to the “Max primary flow” menu.
Thereafter the primary flow is reduced by 5 degrees per
day again until the temperature is down to 25 °C.
Example:
As a general rule, a
Primary flow reduced value of 3 to
4°C is equivalent to a reduction of approximately 1°C in
room temperature in a normal system.
