3.5.3.9. ÄssäControl-cooling, free (accessory)
To the heat pump collector can be installed a cooling system, where the
heat transfer fluid is circulated in
with a room temperature sensor, cooling circuit temperature is automati-
cally adjusted to the desired room temperature. Without the room sensor,
the system is cooling at maximum power. Free cooling is an energy-effi-
cient way to cool the property, as the operating cost only consists of a
circulating pump and energy consumption of the cooling fan motor. The
cooling setting values can be modified under Other settings and Cooling
(Note! The cooling-function is acquired).When taking the cooling system
into use, the cooling control mode is set in the service menu. In the
service there is following selectable control modes: Room temperature,
External and Manual.
Room temperature
Room Temperature menu provides the cooling temperatures, which deter-
mines when the cooling system is running. In addition, the menu will
display the current room temperature, coolant temperature, humidity, and
dew point value, as well as system status heating / cooling / off).
Use the button in the bottom left corner to return to the home screen. Use the arrow button in the bottom right corner to return to previous screen. For
instructions screen, press the 'i' button in the top right corner. In case of operation faults, an alarm button is displayed on the top bar.

the building. If the system is fitted
External
When the control mode is External, cooling is controlled by an external
thermostat, which is connected according to the wiring diagram.
Manual control
When the control mode is set to Manual, this menu can be used to
switch to active cooling. The system tries to keep the coolant tempera-
ture at a minimum of one degree above the dew point. From the menu
coolant temperature can be set to be constant, where the dew point
effect is not taken into account.
3.5.3.10. ÄssäControl-cooling, flexible (accessory)
Flexible cooling allows for a more versatile and more efficient cooling. In
the flexible cooling, there are six different control modes:
1. Heating
Ground source heat pump uses the ground loop by transferring
energy to the storage tank for heating or hot water.
2. Heating and cooling
Ground source heat pump heats the boiler by transferring heat
from the refrigerant circuit and ground loop to the storage tank.
This function is available when heating and cooling is needed
simultaneously.
3. Passive cooling
Ground source heat pump cools the cooling circuit by transferring
heat to the ground loop. If the coolant circuit temperature has not
reached the set value, in the time available (the display section
Delay), becomes passive cooling automatically active cooling
