Config/Zone
The DFC control is activated by entering a value that is different to zero for one of the
two following parameters or the “Water start temperature or water hysteresis” parameter.
➊. Air start temperature (zone parameter)
The operating modes FC, EFC and MIX are enabled below the outside air temperature
that is set as the start temperature.
➋. Relative air start temperature (zone parameter)
The operating modes FC, EFC and MIX are enabled below the return air temperature
reduced by the relative start temperature.
➌. Hysteresis (zone parameter)
The operating modes FC, EFC and MIX are blocked with this hysteresis. Cooling can
then only take place in the DX operating mode.
➍. Water start temperature (zone parameter)
The operating modes FC, EFC and MIX are enabled below the water temperature
that is set as the start temperature.
➎. Relative water start temperature (zone parameter)
The operating modes FC, EFC and MIX are enabled below the return air temperature
reduced by the relative start temperature.
➏. Water hysteresis (zone parameter)
The operating modes FC, EFC and MIX are blocked with this hysteresis. Cooling can
then only take place in the DX operating mode.
➐. Delay time (zone parameter)
The evaluation of the average value is delayed by this time.
➑. Standby units (unit parameter)
A zone must contain at least one standby unit if sequencing is supposed to take place
in it. The current unit is declared as a standby unit with setting “1”. This setting defines
the starting status of the sequencing and changes according to the current sequencing
status.
The upper line shows the operating state of all units that are assigned to zone 1. The
operating states of the units with the bus address 19 to 0 are displayed from left to right.
0 stands for normal operation, 1 stands for standby mode.
In the line below, you can specify the operating state of the unit.
0 means normal operation, 1 means standby mode, like above point ➑
