Night reduction
(you access the menu directly from the main menu)
This menu is used for night reduction settings. Night reduction means reducing
the temperature indoors during scheduled periods, e.g., at night or when
you are working. Two types of night reduction are available: “Week prog.”
for scheduling daily reductions and “Block” for scheduling night reduction
periods lasting several days.
If only one radiator circuit is defined, the first menu window for selection
of radiator system is not displayed.
Active
Here you select if the scheduled reduction should be active, “Yes”. If “No”,
no reduction takes place at all.
Type
Type of reduction is selected here:
“Week prog.” means scheduling reductions during all weekdays with the possibility
of two reductions per day. The schedule is repeated every week. “Block” means
scheduling reductions during several days of the week, e.g., Monday to Friday.
Two reduction periods can be scheduled. The schedule is repeated every week.
Room reduced °C
(alt. Primflow reduc. °C)
Here you decide how many degrees the room temperature is to be reduced during
the reduction period. NOTE: “-2” means that the room temperature is reduced by
2°C from the regular temperature. If room sensors are not part of the operation,
it would be the primary flow temperature for which you indicate a reduction instead.
Rule of thumb: 3-4°C reduction of the primary flow temp equals approx.
1°C reduction of the room temp in a normal system.
Week pr. or Block
The scheduling is done in these menus; see next section.
