Note: If the Flash adaptation function is already configured with a small cycle time,
the
Adaptation function should not be configured as well.
5.9 Cooling control
Cooling control with outdoor sensor
When the cooling control function is activated in a control circuit, the four-point
charac- teristic of the corresponding control circuit is automatically activated
and the operating direction of the control output is reversed. In PA1 the four points
for the course of the set point based on the outdoor temperatures can be
adjusted separately for day and night mode. The Base point for return flow
temperature that can be adjusted with an active re- turn flow sensor determines
the point at which a minimum limitation of the return flow temperature starts: If
the measured return flow temperature falls below this value, the flow
temperature set point is raised. The four return flow temperature values in the
four-point characteristic function have no effect.
