5Control description
All the control parameters of the KJ Mandík can only be set on the Climatix controller from
the integrated HMI control unit, HMI-DM control unit, HMI-TM control unit, and HMI@Web web
interface. A partially limited parameter setting can be made from the POL822 room unit. The other
controls are only used to switch on the unit, set the required temperature, set the required fan
speed and possibly set a regime or specific function.
Home screen5.1
The basic initial screen of the controller after user login is shown in the figure (Fig. 1) with
the following information:
1. Line –system information about the
access level (PIN level), type of AC unit
and, if applicable, the number of the
selected line on the current screen. For
the display integrated in the controller,
in case of an alarm, a bell is displayed at
the end of the first line.
2. Line –current date, time and
temperature according to the configuration (room, supply or exhaust air). The date and time
can be changed by entering the service PIN.
3. Line –ModeSelection allows the user to enter the required regime.
4. Line –The current regime is displayed including the required temperature corresponding to the
regime and temperature period. Additional information is the display of the auxiliary regime
(the “AM” symbol at the beginning of the line) and the switching on of the unit from one of the
controllers without communication (the “•” symbol in front of the current regime). If the
auxiliary regime symbol is displayed, the setting for the current regime may not be observed.
The specific auxiliary regime is then specified on the last line of the home screen under the
AuxilieryMode writing.
The next lines contain menu items for further setting of the AC unit parameters.
The next figures will show the login level required to view them in the top left corner of
the screen.

Operating and auxiliary regimes5.2
The AC unit can operate in four basic operating regimes: Off, Tempering, Economy, and
Comfort. Each of these regimes can be set fixed from the display, from the control panel, from
external switches, or according to a time program.
The auxiliary regime occurs when the unit cannot meet the requirements of the basic
operating regime, for example, when the unit starts up. The auxiliary regime symbol “AM“is
displayed before the current regime. The specific auxiliary regime is displayed on the last line of
the home screen and the device component screen.
5.2.1 Selecting the operating regime
The ModeSelection line is used to specify the type of operating regime required of the unit.
The current operating regime is displayed on the next line of the display, including the required
temperature. The user can select from the following operating regimes:
TimeSchedule, Off, Tempering, Economy, Comfort
The Economy operating regime usually differs from the Comfort operating regime by
having a lower required temperature, lower fan speed, and lower fresh air quantity. The speeds
for the Comfort and Economy operations are set in the ComponentsMachine  Fans.
Temperatures for the operating regimes are set in ComponentsMachine 
TemperatureRegulation. Fresh air quantity is set in ComponentsMachine  Dampers.
5.2.2 Off regime
In this operating regime, the AC unit is turned off. Only safety functions that are designed
to protect certain parts of the unit from damage may operate.
5.2.3 Tempering regime
In this operating regime, the AC unit is off by default and is in one of the following
additional regimes:
Standby –the unit is switched off and only the safety features are operational to protect
some parts of the unit from damage.

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)
