Assembly and installation 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 20.1.
DIP switch no. 2
It is essential that DIP switch no. 2 is set to 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: including
changeover in a 2-pipe system (see section 19.3).
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
Alternatively the changeover between heating and cooling in a 2-pipe
system can also be activated by a clip-on sensor. In this version, set DIP
switch no. 4 must be set to DIP 4=OFF (see section 19.4).
DIP switch no. 5
The convector configuration (2-pipe/ 4-pipe) is set by means of DIP switch
no. 5.
DIP switch no. 6
There is an option of using the internal sensor in the KaController or an
external room temperature sensor for room temperature control.
DIP switch no. 6 = OFF Room temperature control to an external room
sensor
DIP switch no. 6 = ON Room temperature control to the internal sensor
of the KaController or the selected sensor on the
master unit
With slave units, DIP switch no. 6 has to be set to ON if the room
temperature is detected via the external room sensor of the master
unit or the KaController.
