FrostProtect
– frost protection of the room occurs if the temperature in the room drops
below the required temperature. The unit will start and switch on its heating components. If
the unit includes a mixing damper, 100% air circulation will also be used. The unit will shut off
when the required room temperature is reached. This additional regime is typically used in
the winter when a building is not used for extended periods of time. The start of the
additional regime is indicated on the next line below the selected regime by the
FrostProtect
sign and required temperature. The fan speed may correspond to the
Comfort
or
Economy
regime, depending on the last operating regime started. The required temperature is set in
the
ComponentsMachine
TemperatureRegulation
menu through the
FrostProtect
(5 °C)
variable.
Freecooling
– this regime is typically used in the summer to freely ventilate the building at
night with cooler outside air based on meeting temperature conditions. Starting the additional
regime is indicated on the next line under the selected regime by the
Freecooling
sign and
required temperature
.
The fan speeds may correspond to the
Comfort
or
Economy
regime,
depending on the last operating regime. The required temperature is set in the
ComponentsMachine
TemperatureRegulation
menu via the
Freecooling
(18 °C)
variable.
Ventilation must be enabled in the
Configuration
menu via the variable
Freecooling
(
Yes
).
The
other parameters are set in the
ComponentsMachine
Freecooling
menu and are described
in a separate chapter.
Humidity
–
this condition occurs when the upper or lower humidity limits are exceeded, and
humidity monitoring is enabled in the
ComponentsMachine
HumidityRegulation
menu,
while the unit is off, including setting the menu fan speed to a non-zero value.
AirQuality
–
this condition occurs when the air quality limit is reached and at the same time
air quality monitoring is enabled in the
ComponentsMachine
AirQuality
menu with the
unit off, including setting the menu fan speed to a non-zero value.
5.2.4
Attenuation regime
In this operating regime, the AC unit is switched on in the so-called Economy regime,
where the required fan speed and the required temperature are lower by default compared to the
Comfort regime. The required speed and temperature are user adjustable for summer and winter
separately. The control controls the individual components (heating, cooling, and humidification)
