On MCH200000 is possible to perform the change over from Hetaing to Cooling only via Digital Input or via the controller keypad.
On the MCH2001030 instead (which is the Secons edition Controller), you can also perform the changeover on automatic by using one of the controller probes and setting up the setpoint using parameters R23 and R24.
