Freecooling can only be started automatically if the AC unit is in its
Tempering
regime, and the
necessary temperature requirements are met!
State
(
Off
/
MinTempOut
/
TOutMax
/
TSupMin
/
Err
/
On
)
– informs about the status and possible
reason that prevents the start of freecooling.
Off
– freecooling is not activated.
MinTempOut
– freecooling is blocked because the outside temperature is below
MinTempOut
.
TOutMax
– freecooling is blocked because the outdoor temperature is greater than
the room temperature minus
Shift
.
TSupMin
– freecooling is blocked if the AC unit includes a water heater and the
supply temperature is less than 7 °C.
Err
– freecooling is blocked because one of the temperature sensors has
malfunctioned.
On
– freecooling is active.
Required
(18 °C)
– required room temperature. If the room temperature is higher, then
freecooling is enabled.
Shift
(5 °C)
– the outside temperature must be at least this much lower than the room
temperature for freecooling to be enabled.
MinTempOut
(10 °C)
– minimum outdoor temperature at which freecooling is no longer
allowed because the room could become too cold. At this temperature, freecooling is
immediately switched off independently of
MinOn
.
MinOn
(30 min)
– freecooling will stop when the room temperature drops below the required
value if the set time has elapsed at the same time.
Controlled
(
No
/
Contact

Scheduler
)
– informs about the way in which freecooling is
currently switched on.
TemperatureCondition
(
No
/
Yes
)
– defines the start of freecooling, depending on the outside
temperature.
No
– allows freecooling to be switched on without meeting the outside temperature
requirements.
Yes
– allows freecooling to turn on only when the required conditions for the outside
temperature are met.
