System types for cooling application
‣ 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 19: 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 (analog input AI1 ... AI2).
NOTICE
Control mode temperature ΔT-const.:
In the pre-defined applications, the signs and setting ranges for the setpoint 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 ac-
cording to the desired effect.
