Table 50: Heating & Cooling
When the controller type (6.3.1 Controller type) is chosen as heating and cooling, the upper shown
settings are available.
By the setting for the system, the used system can be chosen. When a combined heating and cooling
system is used, the setting 2 Pipe system must be chosen. When a divided system for heating and
cooling is used, the setting 4 Pipe system must be chosen.
Furthermore it is possible to choose between an automatic and a manual switch over.
4.5.7.1 - 2 Pipe system
At a common pipe system for heating and cooling, only one communication object for the control
value is available. Before changing between heating and cooling, a switchover must occur. The
control value can also have only one controller (PI-continuous, PI-switching, 2-Step control). Also the
direction must be identical for heating and cooling. But the parameter for the heating and cooling
process can be defined individually.
