Technical Manual – Room Temperature Controller SCN-RT1
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 (as described from 4.5.2 to 4.5.4).
The following illustration shows the setting option for a 2 Pipe system:
