After having selected the desired system type and control mode for the "Heating" applica-
tion, select the control mode for the "Cooling" application.
System types for cooling application
‣ Ceiling cooling
‣ Underfloor cooling
‣ Air-conditioning device
‣ Concrete core cooling
‣ Hydraulic shunt
‣ Differential pressure-less distributor
‣ Buffer cooling
‣ Heat exchanger
‣ Re-cooling circuit
‣ District cooling circuit
‣ Basic control modes
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 selection
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 set-
point temperature (ΔT-const.) 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
configured according to the desired effect.
