Table 23: Selection of system type and control mode for "Cooling" application
Every control mode, with the exception of speed n-const, additionally requires the se-
lection of the actual value or sensor source (analogue input AI1 ... AI4).
NOTICE
Control mode temperature ΔT-const.
In the pre-defined applications, the signs and setting ranges for the setpoint tem-
perature (ΔT-c) are pre-set to match the application and thus the effect on the
pump (increase or reduction in speed) is pre-set.
When setting via "Basic control mode", the sign and setting range must be con-
figured according to the desired effect.

If the selection is made, the sub-menu "Setting assistant" will appear with the display
of selected system type and control mode.
NOTICE
The menu "Heating/cooling switchover" for further adjustments is available only if
all settings have been made for "Heating & Cooling" application.
