Installation and operating instructions
Parameter P44
Parameter P44 is used to set the function of the digital input DI2 when DIP
switch no. 4 = OFF.
The digital input DI1 is predominantly used to execute specific functions. If
the use of the digital input DI2 is needed, then the following settings have
to be made:
1. Set DIP switch no. 4 to OFF.
2. Configuration of the digital input DI2 using parameter settings P44.

If DIP switch no. 4 is set to ON, digital input DI2 changes over from
heating to cooling in a 2-pipe system.
On the KaDeck, the digital input DI2 is connected to GND via a
factory-inserted electrical jumper. The KaDeck is therefore pre-set as a
cooling unit.
