Installation and operating instructions
DIP switch no. 1
DIP switch no. 1 must be set to ON to actuate a KaControl by means of
0…10 V signals within a building management system provided by others.
The parameter settings required are described in Section 6.1.5.7.
Factory setting: DIP = OFF
DIP switch no. 2
It is essential that DIP switch no. 2 is set to OFF.
Factory setting: DIP2 = OFF
DIP switch no. 3
Optionally install a clip-on sensor to monitor the water temperature. The
following functions can be triggered by a clip-on sensor:
1. Actuation of the fan stages when the hot or cold water is registered on
the heating element (Auto-Eco function, see section 10.3.10, manual
I537).
2. Heating/cooling changeover function in a 2-pipe system (see section
6.15.3)
3. Unit frost protection (see section 6.10.1, Troubleshooting A17)
If a clip-on sensor is fitted, DIP switch no. 3 must be set to ON.
KaControl units are delivered as standard without a clip-on sensor and DIP
switch no.3 is set to DIP3 = OFF.
Factory setting: DIP3 = OFF
DIP switch no. 4
In a 2-pipe system, changeover between heating and cooling is activated as
standard by the switching of the digital input DI2, with the following
operating modes being executed depending on the external contact:
DIP4 = ON + ext. Contact open
Heating mode
DIP4 = ON + ext. Contact closed
Cooling mode
Factory setting: 2-pipe system DIP4 = ON
4-pipe system DIP4 = OFF
Alternatively the changeover between heating and cooling in a 2-pipe
system can also be activated by a clip-on sensor. In this version, DIP switch
no. 4 must be set to DIP 4 = OFF (see section 6.15.3).
DIP switch no. 5
The convector configuration (2-pipe/ 4-pipe) is set by means of DIP switch
no. 5.
Factory setting: 2-pipe system DIP5 = OFF
4-pipe system DIP5 = ON
