General
The condition in order for cooling to be activated is that
"On" is selected in menu 9.3.3 Cooling system. Note! The
climate system must manage cooling operation. Settings
must be made by the installer when commissioning the sys-
tem.
If a room sensor is connected, it starts and stops cooling to-
gether with the outdoor temperature. The lowest calculated
supply temperature is set in menu 2.2.4.
Cooling operated from the outdoor sensor in
operating mode AutoK
If the cooling system is set to "On" in menu 9.3.3 and the
outdoor temperature is greater or equivalent to the set start
temperature for cooling in menu 8.2.4, cooling starts.
Cooling stops when the outdoor temperature drops below
the set value minus the set value in menu 8.2.5.
The calculated flow line temperature is determined from the
selected cooling curve in menu 2.2.2 and the offset for
cooling curve, menu 2.2.1. Limitations, which are not in the
diagram, are included in the control system's permitted min
temperature.

Controlling cooling mode using the room sensor
If RG 10 is present, the condition for cooling is that the room
temperature has exceeded the set room temperature (menu
6.3) by the set value in menu 8.2.5 and that the outdoor
temperature is equivalent to or exceeds the set outdoor
temperature value (menu 8.2.4).
When the room temperature has dropped below the set
room temperature in menu 6.3 by the set value in menu
8.2.5 or the outdoor temperature falls below the set value
in menu 8.2.4 by the set value in menu 8.2.5, cooling
switches off.
